Watercooling dynamics

I recently started to mine bitcoins, so the pc is at full load all the time. I control the fans with the water temperature. I tried different settings: first, I set the fans to 100%@35c. The fans were always on 100% and sometimes the temps exceeded 35c. When I set the fans to run 100%@50c, the temperature went to 40c but the fans now run @50-60%. The cpu/gpu temps haven't changed at all. How does this work? It seems like higher water temperature with slower fan speeds equals the same cooling capacity as faster fans with cooler water.

Anything in my current, fairly old (but water-cooled!), PC worth using in a new one?

I started building computers around the year 2000 and have never really done a complete build from scratch (for myself) after my first. I'd upgrade a part here and there, and over time everything has been replaced multiple times. However, I'm thinking, due to an upgrade hiatus (it took me a LONG time to "beat" Skyrim :-P), I'm at the end of the road. I'm close to the conclusion that, for the second time in my life, it makes sense for a fresh new build. I figure I'd run this past y'all first.
My next computer I'll use for both fun and work. On the fun side, it would ideally play modern games (Particularly, I'm eying Elder Scrolls VI and Baldurs Gate III) on decent settings on my 34" widescreen monitor. Work-wise, it needs to be able to run multiple docker containers and let me do other things (take notes in notion, google docs, etc.) while on a CPU-crushing video call. The budget is $1,500.
Here is my current setup and thoughts on each component:
Photos: https://imgur.com/a/xyM07dx

Things that may be useful:
Operating System: Windows 10 Professional (from upgrading from Windows 7... the DVD is hopefully somewhere)
PSU: Corsair TX850W - It has been trusty for the last eight years, but may not have the needed connectors for today's stuff.
Hard Drive: Crucial MX100 512 GB SATA SSD - 2.5-Inch, No performance complaints (specs claim 6.0 Gb/s), although I'm running out of storage space.
Optical Drive: Pioneer DVD-RW - Do people still put these in new computers? I also have an external USB DVD drive I could use in a pinch.
Case: Chieftec Dragon Mid Tower - this old case is steel and heavy as shit, which is actually nice as my dogs and toddlers are unlikely to knock it over inadvertently. It has a window which I like, although cable management is a massive pain in the ass. I'm not too fond of the door that covers the buttons and optical drive and lost it long ago.
Cooling: Custom water cooling setup - I water-cooled in 2002, overclocking my Athlon XP 1700+ from 1.4Ghz to 2.5. It was awesome. The radiator and T-valve are the original gangsters. I'm on my fifth pump, with my last three being the Swiftech MCP655-B, which I like. The current water block is some D-Tek for the old CPU socket. The radiator is an old Chevy Impala radiator (I think) that this guy I met on a 3DMark (now Futuremark) forum (jb2cool?) custom modified and made a shroud that houses two 120mm fans. I had to drill the shit out of my case to mount this thing in there. I'm very nostalgic about this setup, but it would also be a huge pain to fit into a new case.
Monitor: LG 34UM67-P 34 - 34" IPS widescreen; 5ms 2560 x 1080 60hz; is 60hz too slow these days?
Keyboard and mouse: Logitech Chordless Wave - USB dongle; wrists feel ok, no complaints

Things that probably will not be useful:
Motherboard: Gigabyte P45T-ES3G - I'm pretty sure I won't be reusing this. I also bought it to replace a more bad-ass motherboard that died when my previous power supply died and took it out with it. I do like how it had dual bios, though.
CPU: Intel Core 2 Quad Q6600 - Been impressed with this CPU lasting as long as it has. I wet sanded it down to a mirror finish ready to overclock the shit out of it, but then never got to it as life got in the way.
Memory: 4x4GB PC3-12800 DDR3 - G.Skill Ripjaws; ancient technology. Note: I want more than 16GB ram in my next build.
GPU: Asus Geforce GTX 460 - My previous GTX 460 died at the height of bitcoin, and any modern GPU was stupidly expensive. Replacing mine was only $30 on eBay, so that's the route I went.

tl;dr: are any of the above bolded components still worthwhile in a modern PC build?

Mining profitabilty tanked?

I know coin prices are down, obviously. But my 1080ti was getting around $8 a day before and now I'm lucky if it gets $2..is everyone getting this bad of results or is something wrong with my miner?
submitted by Alltimegamers to NiceHash [link] [comments]

I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O

Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.**

A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it:

- Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have.

- My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's.

- I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose...

- I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS.
______________________
Q2) What is your maximum budget before rebates/shipping/taxes?**

* A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK).
______________________
Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.**

A3) IMMEDIATELY! :)
______________________
Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)**

A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\* 
______________________
Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?**

A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference?
______________________
Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.**

A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean).
______________________
Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?**

A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science).
______________________
Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)**

A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well.

- This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\*

- I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\*

- Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\*

- Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts.

- Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?)
______________________
Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?**

A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports.
______________________
Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?**

A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though.

______________________

______________________
Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc...

Naturally, I have GPU's. Specifically;

At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one.

I also have some GTX 1080 TI's but those are already spoken for, sorry.

It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP.


In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well...
Rig 1 = EPIC NAS SYSTEM
Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL

Oh, I almost forgot... The current routers I'm using are...
1X Netgear Nighthawk 6900P (Modem + Router)
1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one)
1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices.
---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :)


Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years.

TIA for assisting in any way possible. Gotta love the internets!


THE END.
:)

EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here...

I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent.

One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind.

I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids.
Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).*
I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows:

EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else...
(Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT).
Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner:

*** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\*
Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. =
'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat.

I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale.

Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/.

THE END (Round#2)

AMD Threadripper 3970x - My adventure so far (Will edit as I go)

I own a gaming community called Unknown Skies gaming (For a little Context) and we are planning a server upgrade. Currently we have a Dell R620 with Dual E5-2690 V2's Running @ 3.3Ghz, has 196GB Ram. The game we host on this rig is called Empyrion Galactic Survival.
The reason for the upgrade is currently the server just isnt high end enough to continue supporting our target playerbase of 100 players, and Performance has dipped due to the game being alpha and the devs are not doing much to improve server side efficiency. Back in 7.0 we could host 150 players on this machine, now it struggles with 60... Yeah big change in 2 years.
After a lot of research... I can clearly see Intel Xeon Gold 6154 CPUs (2 of them) do not outperform even the R9 3950x according to passmark. The price of these used intel servers is stunningly high on the used market... Dual 18 Core XG 6154 Processors with 128gb ram (Dell R740 I think, feel free to correct me) cost right around 10,000$ USD Used give or take 1000$ or so... And get stomped on by an 800$ Single Socket CPU... Thats new and has a warranty... I get that it doesnt support as much memory... But Dang...
So I looked into threadripper... HOLY SHAT!! The 3970x hits 60k+ in passmark... And the ENTIRE system with a custom cooling loop is less than 6 Grand? Thats nuts to me! Amazing Deal! Im sad all my servers and rigs are intel hahahahaha.
What we need, What im aiming for, and my thought process - Feel free to leave thoughts and suggestions..
AMD Threadripper 3970x (Because High Per thread throughput matters due to shit code, and more players on a playfield means more cpu usage on that thread, Lots of threads matter as every playfield opens a new PlayfieldServer.exe and is its own instance so the more spread out players are, the more cores you need to spread out workload. 32 cores 64 threads... NICE)
Corsair Vengeance LPX 256 GB (8 x 32 GB) DDR4-3200 Memory (Each player uses around 1-3gb ram, 2 on average, goal was 100 Players)
ASRock TRX40 TAICHI ATX sTRX4 Motherboard (Thought this was a solid selection given the options I saw)
EVGA 1000 W 80+ Gold Certified Semi-modular ATX Power Supply SHOULD be sufficient with a closed loop water cooler, all SSD's and not requiring a gaming GPU (Plan on a 1050ti / 1050 at most)
Case im using is a modified 4U rackmount case with 3x 120mm fans going in the front, radiator behind those. Could NOT find one that I didnt have to modify. Went with El-cheapo option cause imma be drilling it and modding it internally - Rosewill Server Chassis Server Case Rackmount Case for Bitcoin Mining 4U off ebay I think it will work, and if not I have a file server that would LOVE the home LMAO. So it was well worth the Chance.
Water cooling Solution I settled on was a Thermaltake Floe TR4 Edition. I thought about using a Custom Cooling loop, but by the time I priced everything out the way I would do it... It came out to like 500$ ish LMAO. The above cooler From what I can tell should be sufficient, and should fit in the case i chose. Tight fit, but should fit.
Im excitedly looking forward to the build :) Anyone have any experience with any of this and care to chime in?

Number crunching/Deep learning machine needed

Hi,
I have tried to build my own, but it appears like I've gotten rusty in this. It has also reached prices beyond my expectations. But I want to keep it for about 7-10 years.
What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.
I don't plan to use this for gaming or bitcoin mining. I will process a lot of text from external sources, compute numbers, and train some deep learning models.
What is your maximum budget before rebates/shipping/taxes?
4000 USD / 36000 NOK.
When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.
ASAP
What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc)
Things I would want:
CPU: AMD Ryzen 9 3950X (or something fast that has 16+ cores; I will run highly parallel jobs) GPU: GeForce RTX 2080 Ti (large memory is preferred) Memory: 32GB (or more) Motherboard: Preferably an X570 with PCIe 4.0 NVMe support. WiFi would be nice, because there is no network cabling around that area. USB-C heads would be nice, but not required. Case: USB-C is required. I prefer white, silvegrey, but black would be fine as well. No disc drive needed. Storage: NVMe (1 TB should be enough for me, I suppose). I already have an SSD inside my old machine. PSU: 850W or higher would be good. I have plans to install another card in that. Fans: I have no idea how many I need, nor where to mount them. Something less noisy would be nice. If water cooling is less-noisy and comparable in terms of pricing, I can go for water cooling.
Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?
Norway
If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.
SSD (Samsung evo 850), keyboard, mouse, monitor. Brands of those don't matter.
Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?
Most likely, no. However, it appears like both the CPU and the GPU can be overclocked to a certain extent.
Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)
CUDA and OpenCL support would be required. I already have an SSD. But an NVMe drive is needed.
Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?
I don't like LED lighting. I prefer white, silver or grey cases. Size doesn't matter as long as I can place 2 full size PCIe cards in that. I don't like window, but don't mind if a cheap model has that.
Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?
No. It will run Linux.
Extra info or particulars:
Nothing apart from those.
I would be very happy, if you could help me build something along these lines.

What is Dago Mining?

Green energy for bitcoins, ethereum, and other cryptomonetes mining. Dago Mining has one initial cost and zero cost on consumption. The cost of the energy component gives profitability to mining. We create our own green renewable energy power plant and we will not have any future energy cost increase. There is no cost per Kw schedule, only a small annual maintenance price (0.01 $ per Kw), with a 20-year warranty on plant's components.
About Dago Mining When cryptomining was still in its infancy, it was well distributed among a couple of thousand private miners, governed by transparent rules and not harmful to the world environment because the energy requirements were microscopic. During last years, all this has changed: Dutch bitcoin analyst Alex de Vries, who operates a Bitcoin Energy Consumption Index on the website Digiconomist, has produced estimates of growth of energy consumption and they are alarming. If bitcoin miners are using the most efficient machines possible, the lowest amount of electricity they could possibly be using is 39 terawatt hours, de Vries said in an interview. That's about as much as the entire country of Slovenia. De Vries said less conservative estimates make it entirely possible that bitcoin is using as much energy as Ireland, which consumes about twice as much as Slovenia, or about 1 percent of the U.S. total.
The problem is getting worse, said de Vries, who estimated the annual amount of energy consumed by bitcoin rose by a fifth in the final weeks of 2017. Even worse, the concentration of mining power in the hands of a couple of large corporations is distorting the formerly democratic decision- making process in these networks: changes in protocols and hard forks are in danger of being influenced by the economic interests of a few.
DAGO mining has designed a mining system with three technologies all together: a high efficiency photovoltaic system that uses solar concentration panels, combined with an innovative energy storage system in salt water batteries that will bring the farm to be self-sufficient in terms of energy in 12- 18 months from the start. The progressive construction and assembly of the hardware of mining uses high performance GPU (not only Graphics Cards) and ASIC Chip already on the market. Everything is cooled by “Immersion Cooling” in order to exploit the possibility of overclock without losing stability and durability. Using the dynamics of exponential growth for both, we promote climate preservation and the welfare of our token holders. It is the physical incarnation of the blockchain spirit: a robust and decentralized system that can withstand disruptions in government policies, price structuresand the energy supply.

7GPU build is losing its mind freezing. Testing for failed parts is tedious

Feel free to laugh at my career ending $12,000 blunder.
I did have this whole thing stable for about 1 day, but now it's all gone to hell. I attempted a server rack mounted build similar to the Linus 7 gamers 1 PC video.
Parts List:
Observations:
Any thoughts? personal experiences to draw on? At this point, I'd settle for just random ideas? Should I try rolling the Bios from 3502 back to 3402? Maybe run all GPUs off external power and only the motherboard and CPU off a main PSU?

Cloud-Mining Solutions

Cloud-Mining Solutions

MINEMUSE

MONEY: BY THE PEOPLE, FOR THE PEOPLE

In order to get started mining Cryptocurrency, cryptocurrency miners will need dedicated computer hardware with a specialized graphical processing unit (GPU) chip or application-specific integrated circuit (ASIC), sufficient cooling means for the hardware, an always-on internet connection, which makes it a little bit complicated and expensive to mine cryptocurrencies…

Well, MINEMUSE is here to solve those problems with the use of Cloud-Mining, To make mining truly accessible, profitable and Hassel free for everyone and is more cost-effective, we at MineMuse have come up with a solution. We are manufacturing our own ASIC for future use. We will be creating our own electric power using the natural resources available, which will reduce our costing for mining; also with its use, we will be able to mine more quantity in less timeframe. Manufacturing our own ASIC will result in less expenditure for the hardware to be used. We are also planning to sell further our own manufactured ASICs to other mining corporations, which will help us in growing along with the profits.

MINEMUSE uses over 7,000 to 10,000 ASIC and around 50,000 GPU through which the mining takes place. This ASIC is specific for each coin. These are huge types of equipment that generate a lot of heat while processing, so the colder climate/regions help in keeping these types of equipment cool and also reduces the costing for the power. These ASICs are made up of a number of GPUs.

MINEMUSE actually makes it possible for investors to invest using cryptocurrency and other payment methods such as PerfectMoney and Payeer, users would be able to earn daily dividends on their investment depending on the package they chose.

The crypto mining business sector is highly dependent on energy supply. The price and availability of electric power are the two most important factors for mining companies. Electric power is the medium through which maximum profit for mining can be generated so the, more emphasis is laid upon to conserve the electric power.

To be efficient and to meet the best requirements in terms of low-cost electricity supply we have established our mining station in these regions and also have the access to many natural resources which helps in reducing the infrastructure to be used and increasing the overall profit.

MINEMUSE uses the following natural resources to generate electricity which makes it practically possible to mine cryptocurrency.
FOSSIL FUEL RESOURCES
The non-renewable natural energy sources like coal, natural gas, and oil, which are formed using the plants' and animals' biomass. These Fossil Fuels are carbon-based and currently supply most of the human energy requirements.
WIND TURBINES
Wind power converts the kinetic energy in wind to generate electric power. This is achieved by using a large wind turbine, the turbine can be connected to a generator to generate electricity or the wind used as mechanical power to perform tasks such as pumping water or grinding grain.
BIOMASS
The organic, non-fossil material of biological origin mainly like wood and wood waste, biogas, biofuels and the organic fraction of municipal and industrial waste is used to generate heat production or electric power.
WIND ENERGY
We convert the kinetic energy of wind into the electricity in the wind turbines.
SOLAR ENERGY
The solar radiations are exploited for heat or electric power.
MINEMUSE uses the above natural resources to generate natural resources
MINEMUSE makes it simple and easy for investors to mine cryptocurrency through Cloud Mining Or Remote Mining the main reason for the existence of this model is the fact that the increasing difficulty of mining has made it unprofitable for people to start mining at home.

The more accessible model for remote mining is cloud mining, where a part of the mining hardware is purchased by the miner which is hosted and owned by a mining service provider. Here the requirements such as the configuration of the hardware, maintaining uptime and selecting the most efficient and reliable pools are taken care of by the service provider.
There are a lot of pros that this option provides: instant connection (i.e no waiting time and delivery risk for hardware shipment), static maintenance and no issues related to noise, heat or space for mining.

Below are the packages that Users can choose when signing up.

Investors can invest in MineMuse using the following payment methods...

Bitcoin, Ethereum, Bitcoin Cash, Litecoin, PerfectMoney, and Payeer.

Should I upgrade my AMD 7970 to a GTX 1080 with my current build?

I have an old bitcoin mining rig that in its hayday used two water-cooled 7970s. Only one 7970 is still working and I'm wondering if it is worth upgrading just the GPU or waiting to upgrade everything. Here is what I currently have.

I mostly play Mechwarrior Online but above medium settings the graphics card glitches and occasionally shuts off. Additionally, I play around with hacking CTFs and I occasionally have to crack a hash.
What would you recommend with $1000 US? I really liked how quiet the watercooled system was but didn't like the hassle of cleaning out the water. So I was looking at the a hybrid like this GTX1080. Does it still run quietly or should I save up a little extra and get something with more overkill?

I found some pictures of my old FalconNW gaming rig from 2012 if anyone is interested.

I bought it with my tax return in 2011 and sold it in 2012 for about half of what i paid. Here's the specs:
Cost: $6500.
Pictures here
By far the dumbest purchase I ever made. I regretted it from day 1. As soon as I received the computer I was on the phone with tech support. Credit to FalconNW, their tech support was excellent, they stayed on the phone with me for hours debugging my graphics issues even after business hours.
My main issue was the quad sli. It would have been nice if they warned me up front that quad sli was barely supported at the time and not really supported at all in games. They just wanted to sell me $1800 in graphics cards. I got the best performance disabling SLI altogether and running everything on half a card. Hence why I sold it a year later.
The coolest thing I was able to do with it was mine bitcoins and run gpu tasks in boinc. It absolutely crushed heh but still wasn't powerful enough to compete with the huge mining pools so it wasn't like I was going to be making any money from it anytime soon, plus running the 2 cards at 100% for extended periods of time didn't seem like a good idea so I only dabbled.
So, why did I buy this behemoth instead of building my own? Well, it's because I've been building computers since I was a kid and after awhile it becomes more of a hassle than fun, especially when you have a large family and have to build all their computers as well. Just once I wanted a computer to be shipped to me already built that would work as well as something I built myself and for the most part, it did.

Help needed from tech familiar with botting, C&C, Trojans, etc. I think my friend's computer has been compromised big time, but not sure.

So, sold a friend a computer over a year ago. i5-750, GTX 680, 8Gig DDR3, running Windows 7 64bit. I set it up myself and disabled things like remote desktop, and it had been running like a champ till last week.
Was going to game with him and he said no because his computer wasn't working right. Taking forever to get to the desktop, icons/mouse/games weren't very responsive, and some assorted "weird stuff" (like steam icon disappearing from taskbar). Plus both his CPU and GPU were running at full bore even with just using the desktop and were getting kind of hot (water cooled system).
I offer to have a look and find that it boots fine to the windows intial start and then it's a black screen for a lot longer than normal (SSD) before the login screen. Log in and there's another black screen for at least 5 minutes. When desktop finally starts appearing it takes forever, with a slow mouse pointer, and clicking an icon once it appears slows the system down to a crawl.
I hard reset and then reset the BIOS to optimized defaults, changing any settings needed before trying to boot windows again. No change. He has 2 (paid for) virus scanners Panda & Malware, and Spybot free version. Malware didn't find anything when he ran it, Panda would hang, and Spybot found one high threat file but couldn't delete it. He tried the last restore point he had which helped a bit, but only for a day or two.
To me it looks like there's some C&C shit going on so I have him disable the internet which he does by pulling the power to the cable modem. Windows boots fine and the system runs like it did when I sold it to him (fast). I run Malware and find nothing. Spybot, just the usual low threat stuff. And Panda stalls before even scanning one file (1%) Both Malware and Panda have exclusions that he said he didn't set, and I couldn't clear them.
He torrents and has had a lot of pop ups at the sites he frequents. And he never downloaded anything other than torrents (he thinks). But Panda would warn him of anything fishy so he didn't worry. Check Panda's log and sure enough a lot of intrusion attempts but also something I've never seen before. After 5-6 attempts there'd be a UDP flood at the computer's MAC address. So at that point I'm pretty certain someone has dropped a trojan on him and he's botted or bitcoin mining for the SOB that did it. BTW he's also had a few bank charges (one to a website) that he didn't make, maybe related because he did do some banking on the computer.
I boot to safe mode to see if one of the scanners can catch the malware that it was missing before. Same results with Malware and Spybot, but Panda will now scan till about 5% where it stalls at a file called BOOT_B the first time and BOOT_C a second time. I try restoring and I get an error saying a file was locked (maybe by a virus scanner) so the restore was aborted. I think that might be Panda so I try uninstalling it (still in safe) and then running restore but it doesn't change anything.
So I'm thinking nuke windows and reinstall, which is fine by him, but I'm hesitant. If I knew what we were dealing with I wouldn't have a problem, but I don't and I'm not sure that he wouldn't have issues down the road because he has three other drives (HDD) in the system as well. I'm also confused about the UDP floods, which I've found is used for DDoS attacks (he's not a server). Plus he's using a router so how'd the flood target the computer's MAC, isn't that hidden by the router NAT? So could the router be compromised too?
Anyone got suggestions on how to proceed? I've left him with the internet to the computer disabled till we fix this. And won't install with it enabled to be safe, but what about the other drives do we need to wipe those too? How about the router, should we replace that? I'd rather fix instead of nuking, or at least know what it is that he's dealing with before the erase so I know how to do it safely.
TL/DR I think my friend's computer has malware that I can't find and it's slowing it to a crawl when it's connected to the internet, but the system's fine when it isn't.

A quick guide to GPUs and cryptocurrency.

There seems to be a lot of misinformation going on about cryptocurrency and how it ties into the new and used GPU markets. I want to try to help alleviate some of the false rumors as well as put together a quick resource to answer any questions someone may have. This is not to sway anyone to or away from crypto or anything like that. I just keep seeing threads that go something like this:
OP: GPU prices are so high right now C1: Oh it’s because of bitcoin OP: elaborate C1: bitcoin is mined 24/7 using huge GPU farms. The miners snap up any and every new GPU they find. OP: well I’ll just buy used! C1: bad choice jabroni. The miners run these cards so hot and heavy that they’ll instabreak as soon as you buy them. OP: oh well when will it stop? C1: bitcoin just crashed so we should see some new GPUs in stock soon OP: thanks dude!
This is an exaggerated exchange, but it is based on some of the more common things I see sometimes and it gets the point across. The fact is, a lot of people that comment are trying to be as helpful as possible, and that is absolutely a good thing. The problem comes when trying to water down the information to make it easier to comprehend for a beginner. That’s where I’m hoping this guide comes in. I’ll start off by explaining the process of mining as concisely as possible while still keeping all of the relevant information. After that, I’ll try to debunk/explain some of the myths surrounding mining and GPUs. Let’s hop in.
Mining in a nutshell:
Cryptocurrency mining is the act of using a cpu, GPU, or an ASIC (specially designed device) to solve mathematical equations that verify transactions. That’s a very general definition that we can work with. Within the general aspect of mining, there are different algorithms that are used for different currencies. Some currencies use the same algorithm, so you end up with more currencies than algos. Some algorithms are “ASIC-resistant”, so the best way to mine is with a GPU.
Now how do you actually get paid by mining? That’s simple. Generally speaking, any time any cryptocurrency is sent anywhere it must go through a verification process and will incur transaction fees. Who gets those fees? The same people that verify the transaction, miners. That simplifies the process a good bit, but it is still truthful.
That’s a good bit of background information. Let’s traverse a bit deeper and cover how somebody gets into mining. I’ll start by saying this: Hardly anybody mines Bitcoin. A little more emphasis for the people in the back. HARDLY ANYBODY MINES BITCOIN. Why is that? Because Bitcoin is not profitable unless you are using a high dollar ASIC. That is beyond the scope of this guide, so I’m not going to go there.
There are two ways for the Everyman to mine: choosing a coin and mining through a pool, or using what I call a “smart miner” like NiceHash. For the sake of simplicity, let’s use NiceHash from here on. NiceHash is mostly on par with the profitability of pool mining, and it is also a lot easier to set up. This simplicity is inviting to beginners and experts alike.
With NiceHash, you never actually mine coins for yourself. You sell your hashing power to those that are buying hashing power. You switch between whichever algorithm is most profitable and mine whatever coins the buyers are paying for, however, you are paid in bitcoin. Confusing? Cool, let’s get simpler. Say you have any amount of GPUs in a rig. In order to mine, download NiceHash, set up your account, and press the start button. Now you’re mining with power! In order to make this profitable enough, you’re going to want a rig with multiple GPUs. A common goal is 6-8 GPUs per motherboard w/ multiple motherboards.
So we’ve got all the background we need for now. Let’s tie in some market information. Currently almost all crypto currencies are down significantly, but that doesn’t change the fact that it’s incredibly volatile and could skyrocket in the next week. We have to deal with the fact that yes, crypto is down, but most people will continue mining because it will inevitably go back up. We may potentially see a drop off in miners buying cards until the return of investment goes back up. It’s kind of dismal right now.
Myth Madness:
M: Bitcoin is causing GPU prices to skyrocket.
E: Let’s replace a few words here. This is more accurate: “cryptocurrency is a big factor in the increase in GPU prices.” This is better, but still doesn’t tell the full story. While cryptocurrency is jacking up the demand for GPUs, a RAM shortage as well as the fact that manufacturers just can’t keep up is keeping supply down.
M: Miners snap up every available new card.
E: This one is pretty true, however, most miners aren’t just snapping up these cards at MSRP, they’re paying the same price everybody else would pay. In the market’s current state, the higher prices of GPUs hurt the return of investment especially when the dollar value of cryptocurrency is down.
M: Miners are only interested in AMD!/Nvidia!
E: this one is a common misconception. Some cards do outperform others, but that does not mean 6 rx 580s will outperform 6 gtx 1080s. Generally speaking, the most powerful card for gaming will be the best performer for mining. A 1080ti will earn around 6 USD per day while a 580 may earn 3 USD per day. Return of investment is actually pretty similar if you go by msrps. You pay more, you earn more to an extent. Most miners that are in it purely for profit are going for 1060 6gb and up, or 570 8gb and up.
M: Mining cards are run at full power 24/7 and are useless after they’re done with them.
E: The 24/7 part is true. Most rigs run constantly, but almost all miners undervolt their cards. The power consumption doesn’t do much to the hashrate, but it cuts into overall profit by drawing more electricity than it actually needs. In addition to this, heat is still an enemy as it is with a high performance gaming rig. To combat this, most rigs are in a cold room with as much airflow as possible in the form of multiple case fans, external box fans, ceiling fans, even portable AC units pointed directly at the cards. Miners are all about protecting their investments. The only wear that could be a problem is fan wear, which can be an easy fix.
M: This will pass when bitcoin crashes.
E: Cryptocurrency is in it for the long haul. 2017 was honestly the first year of widespread acceptance of crypto. It’s best to look at return of investment when talking about crypto and GPUs. With crypto down, GPUs won’t be bought as much. GPU prices go down, return of investment gets back to what it was. More GPUs are bought. It’s a huge ebb and flow type of thing.
Let’s go back to the original exchange from the beginning and see how someone could potentially answer the OP.
OP: GPU prices are so high right now. C1: unfortunately, we’re in a phase where manufacturers can’t keep up with the demand for them. OP: why’s the demand so high? C1: a big reason is cryptocurrency. Crypto miners are able to make a big profit off of mid-high end cards, so they buy them as fast as possible. Lower end cards are effected as well because gamers that can’t get the mid-high range are settling for low range to fit in their budget. OP: Well how about used? C1: If you’re getting a current gen Card, you should ask plenty of questions regarding the conditions it was in. Last Gen cards like a 970 or 980 are probably alright and will rival the performance of some 10 series cards. OP: What if I wait it out? C1: I wouldn’t advise waiting it out. It could take several months for this phase to pass. I would buy a 970 or 980 to hold over until prices even out.
That’s a lot more informed as well as being a lot more helpful to the OP. The best advice I can give if you want a high end card is to be vigilant about deals. Some places are offering GPUs at MSRP if you buy other components with it. That’s a great option if it’s your first build. All in all, we’re in a pretty troublesome time for PC building with the price of ram going up as well as the price of GPUs.
I don’t claim to be an expert so if there are any corrections or additions that need to be addressed, please let me know and I’ll fit them in.
