(Help Wanted) WTF crypto-mining awesomness build. 50 x i7-6950x with Titan XP.

[Glennieboyyy007]

yes, that's it. but I can't help with other things. at least you can communicate easier to other people.

 

btw, i didn't quote because you are the OP so you will get a notification eventhough i don't quote (if im right)

GPU mining for Zcash has been out for 2 weeks now and I've been about to get 750+ sol/s with 6 280Xs.

nice, should i fill the systems with rx 480's then?

Im building a few new computers to mine with, any help would be greatly appreciated!

 

50 computers;

i7-6950x

any liquid watercooler that you guys would recommend

TItan XP 12GB gddr5x

Asrock Extreme 3

8GB DDR4 2400

space isnt important, just need to be able to install OS and mining software. Can anyone reccomend a good 64GB ssd?\

no disk drive, OS will be installed through USB

NO OS NEEDED

and any cheap stackable case that may or may not have a power supply combo.

 

Thanks!

 

 

Here's a PCPartpicker link to the build I made... Instead of 1 Titan X, as I had heard that gcn does better, there are 3 R9 390x's. 

http://pcpartpicker.com/list/sxpYLD

 

CPU: Intel Xeon E5-2680 V3 2.5GHz 12-Core OEM/Tray Processor  ($1667.99 @ SuperBiiz) 
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler  ($24.88 @ OutletPC) 
Motherboard: Asus X99-A II ATX LGA2011-3 Motherboard  ($223.98 @ Newegg) 
Memory: Corsair Vengeance LPX 16GB (2 x 8GB) DDR4-2133 Memory  ($87.99 @ Newegg) - Ram doesn't matter all that much I believe
Storage: Western Digital BLACK SERIES 2TB 3.5" 7200RPM Internal Hard Drive  ($118.99 @ SuperBiiz) 
Video Card: XFX Radeon R9 390X 8GB Double Dissipation Video Card  ($362.89 @ OutletPC)

Video Card: XFX Radeon R9 390X 8GB Double Dissipation Video Card  ($362.89 @ OutletPC) 
Case: Thermaltake Core X9 ATX Desktop Case  ($135.98 @ Newegg) 
Power Supply: EVGA SuperNOVA T2 1600W 80+ Titanium Certified Fully-Modular ATX Power Supply  ($382.99 @ SuperBiiz) 
Total: $3731.47
 

You can buy 54 of these, and the case is stackable. I left cooling out as I didn't know how you wanted to proceed, as liquid isn't necessarily effective in most builds, but might be in a 3 gpu build. 

 

Happy mining!

I love it! any way we could make it cheaper by subbing for 8GB of 2400 ram, 64GB SSD, and a cheaper case?

and also the total TDP of the system is only 1056 watts can you sub out the power supply too? maybe 1200 watts?

http://pcpartpicker.com/list/gmn44C

I replaced the 2x8 2133 with 2x4 2400

I also replaced the 1600 with a 1200, as the estimated tdp on PCPartPicker can be both higher and lower.

 

I left the case, as Thermaltake is a good brand, and many cases are not safely stack able. 

You can now have 58 of this setup.

what are your thoughts on networking, could i put everything on the 5ghz band of my business class wifi?

[BlueCrazii]

Just to be secure if i would do this kind of thing just wire everything so it doesn't overload your wifi

[yoyodapro]

my computers will only be mining on the 5ghz band and i have a 150 down 50 up connection

I'd just do it all wired Ethernet.... Less interference... All of that networking would be so susceptible to interference. The motherboard that I added to the build comes with 1 gb ethernet. 

 

https://www.amazon.com/NETGEAR-ProSAFE-M4100-50G-POE-50-Port-GSM7248P-100NES/dp/B00AUEYWS2/ref=sr_1_2?s=electronics&ie=UTF8&qid=1479057439&sr=1-2&keywords=50+port+hub

You could connect 50 of them to that, then connect that to one more and have that one as a master, the rest as slaves. It costs 1k, so you would need to sacrifice one of the pcs. 

 

Could you just have the master pc do all the networking, and then distribute it out between all of the slaves? IDK, as bitcoining is not my strength.

 

NOTE: I am not that good at networking stuff. This networking stuff is all just educated guesses for me.

I don't know if you are serious or not , but if you had done any research you would know these are terrible builds for mining .

assuming you aren't mining an unprofitable coin .

Cpu's are terrible to mine on whatever the currency , and gpu's outperform them by several orders of magnitude . the titan XP isn't a good choice for mining and cost/performance is way too high to justify it . watercoolers are not a good choice . You're just adding more points of failure .

 

Now if you do want to setup a mining farm , they usually consist of a low end cpu like a pentium , a board with MANY pcie slots ( 1x is the best choice ) ,and LOADS of AMD graphics cards connected through extenders ( since not many data transfers between the gpu and cpu are done , pcie 1x is fine ) . You then buy as many high efficiency power supplies as you need to power them .

 

The most popular choices for gpus right now in mining are either used cards like the hd 7970/7950 , r9 280(x) or 290(x) or newer more efficient and newer cards such as the rx 480/470 ( preferably the cheaper 4gb models )or the fury series cards , which can be had for around 400$. 

 

It's an exercise of efficiency vs starting costs , and only you will be able to answer that depending on what you plan on doing with your farm.

zchash isn't really the most profitable anymore. Back when it launched i would get 15$ a day with my dual 290x's , but i had to switch back to ETC to remain profitable.

Well. I'd say my build is fairly close to that then, taking into consideration the OP's original build ideas. I kept it as close in between the two of those, as the OP wanted to still be able to mine on CPU's. And, considering he originally wanted 1xTitan on each board at x16, I made it better with 3x good AMD cards at x16. And, I picked the AMD cards in between the two commonly used one, the r9 390x. So yes, I am completely serious.

That seems terribly price and space optimized. Considering he'll be getting a crap ton of these, you absolutely want the best value and lowest prices possible. Sure, one component only costs $12 more, but when you multiply that by 40, it quickly adds up to an extra $480 for that component.

Why are there dual CPU's? Aside from that, 2x4 is better (I believe, than 1x8) , and considering how little it adds, even though it adds, up its worth it. 

Also, the EVGA is a much larger brand than SeaSonic, and with a crap ton of these, a good psu is good. The case on the other hand, is a good substitution. I just hadn't checked if it was stackable or not.

Well there is no good coin that REQUIRES cpu mining though .

 

and when talking efficiency , the rx 480/470 is quite a bit better ( a 480 is about as powerful as a 390x for hashrate .)Think about it. for 3800$ , he could get 3 builds like these , which would SMASH a 390x CF setup in ming while using only a bit more power :

I know nothing about mining, I'm just making changes based on space efficiency and value. 2x4GB costs about $20 more.

 

How large a brand is has absolutely nothing to do with the quality of product they produce. Seasonic makes excellent power supplies. However, after rethinking things, this may be a better pick since it's Platinum rated and has a good rating from professional PSU reviewers.

 

And yeah, the case is pretty great. Supports SSI-EEB form factor.

While I still disagree with the Pentium decision, I do like the quad rx 470's. I see no reason to run those at x1 when they could be run at a atleast x8 with the xeon, that the OP seems to agree with. Give me a second to make some changes to the pcpartpicker list with the input.

well the pentium is actually the most efficient for mining when running all the work on the gpu's . There is no reason to get a powerful cpu's for a mining rig as they simply aren't good.

I'm talking from a pure mining perspective , there is no reason to have a xeon . AND if all he plans to do is mine , he does not need to run the cards at more than pcie 1x . All gpu farms run at 1x because you can get more cards per board. 8x doesn't bring ANy advantage for mining .

 

Also, there are 6 rx 470's in the build, not 4 ( 2 of them are in "other" , because pcp wouldn't allow me to put more in the gpu section )
