Topic: 8 gpu rig! Now 10 gpus! (Read 16901 times)
Thanks i will try it , if you have the time to see which bios version have the board, it will be superb.
I tried on a h81 pro btc and it can't boot with more than 6gpu even if they are on 5 slots! So h81 have trouble with this, but the gigabyte z87x works like a charm, the only thing you need to know that you can put only 8 cards from one manufacturer AMD or NVidia.
I have a few H81 probtc, they can boot with 8GPU. 2X7990 + 4X7970 or 2X7990+4XR9 390.
For the pictures : it is an ugly wooden rig and i sold one of the 1070 yesterday! But if you want i will post the pictures these days!
I have 2X7990+4XR9 390 on H81.
I use the ribbon riser. I just set the PCIE generation to 1.

Ah ok it's cards with 2gpu!
Ah the wicked one! Lol
Ah the wicked one! Lol
How do you do to put 10gpu?
I do not understand
He used 4x7990 and 2x1070 on a gigabyte Z87X !
The 4X7990 uses 4 PCIE slots with 8 GPU in total. 2x1070 use 2 PCIE slot.
So he only uses 6xPCIE slots.

I got a powercolor 7990 and tried with 9 gpus , but when windows try to install the driver for the 9th card it crashes in blue screen.
One question , about that 7990 powercolor- it is a bit strange card , gpu-z says the cores are tahiti not malta as the others , and at the same speed as the others 1000/1500 it gives 245sol on every core and the others give 295sol for a core? What could be the problem?

I once tried 6 x 7990s, but it wouldn't work with more than 8 GPUs in Windows, so i gave up trying
I'm surprised you can still mine with your 7990s.. all of mine died after 1 year of mining. 7990s are terrible for mining unless you have them water-cooled.

I have 2 7990 which ran between 80°C - 90°C with stock fans and now run at 56°C - 75°C with 2 x 140mm yate loon fans zip tied to the card mining Equihash.
The stock fans are useless for mining - I hit over 100°C when the card's airflow was restricted i.e. in a case.
Only way is a higher static pressure and higher airflow solution
stock thermal paste on the 7990 is shit, replace it and the pads and they do fine

What model is your mainboard ?
How can you put 7gpus on one board?

was waiting to do the same setup and then read this thread, 4 7990's on zcash pulling 1450w from the wall..mobo gigabyte z97.. thanks! wasnt sure if I had a mobo that would work.
Hi , if you have one more graphic card to put to see if 9 gpus will work? Put on pcie 1234 and 5 if you have time!
Did you overclock it to get this 310sol/s , which driver do you use! Mine work at 1000/1500 and undervolted to 1.13v. Or may be you gave a better cpu?
I wonder if anyone ever bought a HP dl580 server? you can install 8 video cards @ pcie x16 since it does have 8 pci-e x 16 slots plus 4 slots of x8 .. just wondering ..

maximum is 8 gpu for windows driver.... And less on some motherboard that cant allocate resources for graphic memory
Hi i thought it's possible to put 7 GPUs on a rig but seeing this made me confused
tell me what mobo do you have ?
