Hello,

I'm struggling with 6*570 on H81 Pro Btc r2.0. First thing I want to ask, what driver to use for Win7? I know that everything is working on Win10, but I hate it!

5 GPU is working OK with 17.4.4 and this patch, but as soon I plug 6th card, Windows start to load, and then it hangs. Without this patch and with 17.4.4 4 cards work, and 2 are with error.

BR...

Yes, this board is buggy. Wont buy it again. And it seems the quality differs from board to board. Anyway. I reinstall Win 10 completly (rest all data) plug everything in. Boot it and than never touched it again.

You need to set the PCIE to generation 1.

I've already tried and could not make it in ~10h.
However, AMD released driver, which supports up to 12 GPU.
17.10.2 actually..

It doesn't wotk for you?

I have a problem with 5 GPUs, with 4 everything is OK, but with 5 570s I cannot use the monitor, I see blinking gray dots after Windows logo, everything is working but I can work only with TeamViewer.

Windows 7 only supports up to 4 GPU's of the same brand (AMD or Nvidia). This hack hasn't been updated in almost two years and no longer works with the current drivers. Upgrade to Windows 10 for free while you can. The accessibility loophole ends on Dec. 31.

Hello, trying to mod and get warning:

Code:
2018.03.17 13:47:13 Warning - Multiple Catalyst_Version values were found: ""

2018.03.17 13:47:13 Warning - I will now stop, use Force to mod anyway at your own risk!

Should I install old 16.1.1 version?

No idea. It's just a warning anyway. Tick 'Force' and proceed.

Typically Catalyst_Version registry key is present for every AMD GPU in the system. If values don't match - it's weird, they should match.
In your case, looks like it's empty. Probably because new drivers don't have Catalyst at all.

However, mod stopped working when RX video cards came out. And Win10 supports 6xGPUs out of the box..
