Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v6.4 (Windows/Linux)

Guys,

I'm having a hard time getting my new rig to boot Huh

MOBO: Asrock H81 Pro BTC
GPU: 6 x Rx 480 Sapphire Nitro 4Gb
PSU: 2 x Corsair 850 W
OS: Win10 x64

I have two molex connectors powering the mobo with extra juice and I'm not using powered risers.

Everything was running great with the previous video cards (R9 270) but now I can only get the mobo to boot with 3 video cards, and one has to be directly connected to the 16x PCIe.

Isn't it strange? I have extra power available and besides, the old video cards were consuming more power than these new ones.

Any ideas?

Change UEFI settings? Anyone messing with the Gen1/Gen2 setting?

Anything else?

I have another 6x480s coming soon!

Any help will be greatly appreciated Undecided

Thank!

C'mon guys, a lot of you are using the 480 + H81 BTC Pro.

How do you manage to use 6 x 480 on this motherboard?

use powered risers for more than 2 cards

Do you mean I need to use powered risers when using more than 2 cards?

Humm... I've seen a lot of people complaining about the use of powered risers claiming they cause instability problems.

I have a few 1x to 16x powered risers and I'll give it a try. Fingers crossed Tongue

Stay away from the PCIE164P-M-BOARD VER:03 I had about 25 of these and 20 where intermittent and caused random reboots and POST failures.

i replaced with PCIE164P-M-BOARD VER:02's and PCIE164P-M-BOARD VER:05's And 110% stable ever since.
