A question to all the ones using server PSU... How do you power your pci-e x1 to usb risers? Do you use some kind of PCI-e 6 pin to 2xSATA extender? So, a server PSU with x8 PCI-e 6 pin connectors is not for 4GPUs, it is for 3 GPU plus risers..

I'm thinking into buying a really cheap refurbished FSP 500W ATX psu for mobo+cpu+16x GPU, and a server PSU for every GPU with a riser, But I can't see how to power risers only with server PSU without wasting so many connectors. PCI-e 6 pin are made for 150W max, aren't them? So for 75W max from PCI-e connector, that should be a PCI-e 6pin to 2xSATA for 2 risers.

Use PCIe risers that come with 6 pin connectors instead of molex/sata (they are availible now)
Use 1X2 PCIe power cables for the Server PSU, oir get PCIe power splitters, and use the two plugs per cable in GPU Power and Riser Power, thus powering One Card from one power slot.

So, I've been on the hunt for a good MB to do 6+ GPUs with. Awhile back on a hunch I bought the ASUS Z270A PRIME -- 7 PCIe slots and two m.2 slots - I thought maybe I could get 9 GPUs on it. But I was restricted to 4 with the bios that shipped with it.

At this point, however, I have gotten 7 GPUs on it-- the max I have space for right now.

Sharing the details here in case it is useful for someone else:

Here's what I found:

-- Had to flash the BIOS. Board shipped with 5.0.0 and I updated it to the latest (7.0.0 I think)-- this is necessary to get the "Above 4g decoding" option. Which appears on the boot menu in the bios.
-- PCIe switched to Gen2
-- Didn't make other changes.

WARNING WARNING WARNING

When I flashed the BIOS the onboard network hardware stopped working with linux. this caused a bunch of problems.

I had to run this utility to refresh the network drivers ROM to make things work:
https://downloadcenter.intel.com/download/19186

Current setup for this board-
-- Ubuntu 16.04 server
-- 7x NVIDIA 1070 8GB Cards

Working fine. (And about %10 more hash under linux than under Windows.)

Wait! I just found something that might be better:

http://www.silverstonetek.com/product.php?pid=488

- Stackable
- ATX
- 12.2 inch gpus
- fans included (well they´re probably weak but at least they already thought about a cooling solution / air flow...)

Right now I´m investigating further... (how many gpus will fit etc...)

Only a board like the Biostar GT7 which has 4 physical slots could work in a case like this. And this case has 7 PCIe slots so a maximum of 3 cards. You need something with 8+ slots. And dont worry about stackable.

lol .. no. Tyan case and mobo , 8 GPU just fine.

Well what I was trying to do is to keep it small, clean and CHEAP! Wink

min. 4 GPUs are fine

bud there are now risers that have a 6 pin pci express plug housing instead of the molex ones, 6 pin powered risers are much better

print station with exhaust fan, work very well, no more heat accumulating

Nice! Would you mind telling us some details? MB, GPUs, how did you attach the gpus etc?!

yeah sure ,

MB : h81 pro btc rev 1 or rev 2
GPU : sapphire nitro and nitro + 470/480 4gb or 8gb (total 36)
Riser : pci express 1x to 16x rev 005
Psu : 5 leipa maxgold 1000W, enermax platinum 1700W, Leipa platinum 1700W

I screw the riser directly on the shelf . One shelf for MB (2 by shelf) and PSU and one shelf for GPU (12 by shelf)

Right haven´t looked at the slots... so 3 max Undecided

Well I know you could stack almost everything.. but this case looks clean / nice and has got an cooling solution build in.

Anything can be stacked. But the ability to pull out anything from in bw the stack is the what is needed, just like the cases in the server racks.

All you need is a powerdrill, and you can attach rails to anything.

@TheDue - Looks very cool! OUr MB is ATX those cases is for Micro and Mini ATX, not sure if it will fit. I bought the Thermaltake SNOW before which is similar to this and was hoping it would work but it was too small. Yours looks bigger. I will just order 1 to play just to satisfy your curiousity. =)

@ Tasty Potatoe - I have 1, it didn't work for me but I haven't had much time to troubleshoot or more than 1 to know if it's a bad one or not so not sure. Will let other chime in on it but I think best bet is to use built in slot vs another card / connector that can fail.

Everyone is counting 'green papers', no time to write tips and cool stories ;]

I just might think my 'turned to be' a mining rig mobo does not support 6 cards in its PCIe slots. And being short of 1 riser to power the fifth card, what a disaster for me -,-

Has any1 got a card with M2-to-PCIe adapter mining stable? Any fellow forum member who sells/ships such?

Diff is a real b&tch lately!

Which EXHAUST Fan are you using Citronick? THOSE BAIKAL PRINTERS................OH MY, you need a bigger warehouse. These print faster than you can store the money. Too bad I wasn't able to get 1 in before they start setting restrictions.

@ Onefinecoin - Where do you live where it's 50C outside? Holy cow. You will need AC. Sorry that's way too hot as the best you can do with open air / exhaust is to be able to match Ambient. Even with Swamp cooler it will only drop the temp to where I believe is still way above what I would recommend for long term mining. At that kind of temp, I think you either need AC or look for Hosting solutions. However you mentioned that Power is cheap so just use AC. They are printing so much money that it's not a concern right now.

@ ALL other, SHOW OFF YOUR PRINT STATIONS!!!!!!!!!!!!! No need to CLEAN them up or Pretty them up. ALL PRINT STATIONS are $EXY by Default.

@yun9999 - no exhaust fan. Only the blower/sucker fan x 2. But the warehouse is fairly ventilated with windows opened back and front. I am at 35-36c at night, and high of 38c during the day.
Oh yeah baby .... those Baikals are are really magic ... the 25GHs farm is averaging 0.7 - 0.8 BTC per day and that's selling at Nicehash marketplace and get cheap BTC upfront. Never mind DASH, just sell hash to the BTC rich crazy renters at NH.

@ onefinecoin -- wow middleeast! last time I was near there, in Dubai, everything is air conditioned. You might as well rent an apartment and crank the AC 24x7! Btw, during the night, desert climate should get you below 20c no? AC by day, natural cooling at night?

Yeah I guess it has to be such a HUGE vent Cheesy

will post some pictures when I´m done.

About 4U etc... has someone already tried stackable cases? There are pretty cheap ones but I haven´t checked if a H81 Pro e.g. fits or how many GPUS...

@yun9999 - lol yes ! Welcome to middleeast ! But the electricity is cheap so need to test run this coming summer.

Yes guys show us your Money Makers !

@for all those who read this in the future, Rigs = Money makers, cus the altcoins are soaring all time high, really really highhhhh !
