my little Scrypt-Rig

1x Gigabyte HD7950
2x HIS HD7950 iceQ Turbo
ASRock Extreme4 970 Mainboard
AMD Sempron 145 CPU
4GB DDR3 Ram
30GB Seagate S-ATA 7200 HDD
TP Link USB WLan
1000w LC1000 V2.3 Legion X2 PSU
Windows 7 x64

1,96kh/s @ 820w form the Wall

Could you post the link where you got your 1x to 16x risers from? I know of some people that keep running into faulty ones.

hi,

i bought them in a private thread here
https://litecointalk.org/index.php?topic=9605.0 (risky seller!! - when you have much time, you can buy them there)

then i got some here:

http://www.ebay.de/itm/400637555902

and here:

http://www.ebay.de/itm/281232504403

but they have a molex-connector AND get power from the mainboard
so i used this guide to cut the mainboard-connection

I love this thread, for the old gpu-times sake, I'll post what I'm onto right now:



It's going to be an altcoin rig with GPUs (2x 7950 for the time being). It's not finished, but it will have a nice air circulation (there are some plates missing for leading the airflow in the right direction). More to come  Cool

New version of our prototype rig. Still missing 6 cards, waiting to receive the risers.
The rig is delivering 11.6 MH/s in scrypt. Linux + custom monitoring scripts.

An Antminer and Bitfury system running on a 835W server PSU. Not seen in the picture is 2 more antminers, for a total hashrate over 1TH/s


24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe
No longer a wannabe - now an ASIC owner!

Nice one! Takes the crown for 'highest scrypt hashrate in a single rig' !
Very nice and clean design.
What PSUs did you use, how much power does it pull at the wall?

Thanks! This is a z77a-GD65 board, so I may try adding a 7th card for the hell of it. I've got 16 more on the way already. 6mh/s, from one rig? Have to try  Cheesy

I have a pair of EVGA supplies under this one, a 1300G2 and a 1000G2. The 1300 runs the board, riser cables, and three cards, and the second 1000W runs three cards and a SSD. I'm not exactly sure of power draw yet, but I'm sure it's brutal.

I guess 290's have to use signed bioses, or at least they did? Seems someone may have found a way to load voltmodded bioses to 290's, certainly keeping an eye on that thread  Grin

I plan on either buying a kill-o-watt on my way home from work, or swapping in one of the 1500W evga supplies I have with the built in load meter if I can't find a kill-o-watt. I'd rather not mess with that, since the "supernova" software only runs on windows...

So they are running at stock voltage? Not bad. Any overclocking done?

Btw, you seem to have about 10% rejected shares. Anything over 2-3% is way too much imho.
You might want to look for the reasons for that, it is a bit of a waste...

Yes, stock voltage. These are running 995/1500, w/ 20% powertune. Pretty stock settings everywhere else, TC32765 I want to say?

It's a beta multipool (why I edited out so much of the pool details) between the high pool diff and constant switching I think I'm loosing a lot more than I need to. The payouts seem to compensate though, so we shall see if I let that continue. I get much closer to 1% on the pool I usually mine at, though I only let it go for 2-3 hours like that last night.

It seems like everyone uses 1x to 16x risers, even if its plugged in to a 16x slot.  Should I expect any issues with my GIGABYTE GA-970A-UD3P if I use the USB powered risers here http://www.magicgrowing.com/bitcoin-mining/pci-e-powered-riser-card-100cm-40-usb-cable/   ?  I only have a 7970 and an R9 270 right now, just looking to open it up some more.

Got my rig mostly setup, all housed in a homemade rack inside of a closet.  I have 4 more servers coming, the rig generates a decent amount of CPU currency (Primecoin).  I average .077CH/D per server running Xolominer.  Total of 9 servers at the moment. 
Each sever is configured with
-Dual L5420s
-4GB of RAM
-Flash Drives for Boot
Should also note that the cooling setup lowered temperatures about 10-15C, down to 66C. In addition, cut the noise to a tolerable level.

Was looking at investing in liquid cooling and reducing the number of fans for these, but the air cooling seems to do the trick quite well.  Thinking about adding graphics cards to these machines... Can't really decide.

OMG someone finally gets it. Vertically mounted blower fans. I've been saying for a while this would be the absolute ideal fan-direction orientation.

BTW, I don't know how you'd do this and still mount them like you have, but when we took the PCI brackets off of our 290s, there was a significant temp decrease. It was about a 8C drop on our hottest card. You could hear and feel more air move out the back. I got a picture here:


What kinda settings do you use for 875? The best I could get was 850. And what's this about undervolting? Please link the thread?

Thanks! And kudos to the awesome rig!

Yeah, but if noise is problem, those blowers are not an option.

Curious about your power setup:

1. Do you have the two PSU's on different breakers/fuse circuits? Same phase? They can't be on the same 15 or 20amp circuit can they?

2. You said you have three GPUs per PSU but risers on only one?  Shouldn't you be matching the 3 GPUs with same 3 connected risers to each PSU? Ideally the risers and boards should each be on the same rail of each PSU or it could cause some issues for any board that would end up being connected to two different rails or worse two separate PSUs. Assuming you don't have it setup this way, are your pigtails on the risers getting warm?

Countries with 230/240 V @ 50 Hz mains typically accommodate 2400 watts per wall outlet (10 A).

I think it is hilarious how some people look "down" upon GPU mining. Good luck with your ASIC doing Scrypt mining...

/lol, *chuckles reminiscently*

Litecoin mining is very profitable right now.. and you can be in the game without spending a ton of coin on ASIC rigs that have their value cut in half in 15 days time.

which also means that GPUs have resale value when it is time to replace them. While your ASICs are basically a pile of toxic junk after a few months, after difficulty has risen enough to make them unprofitable...
