Hi,

I am running 4x Powercolor Rx 580 Red Devil 8gb with 2x powercolor rx 570 red dragon 4gb with claymore 9.7 and amd 17.7.1 driver. I am mining ethereum only on claymore.

Conditions are;

4x powercolor rx 580 red devil 8gb
2x powercolor rx 570 red dragon 4gb
msi z170a gaming pro carbon mobo
4gb ram
celeron skylake 4400 cpu
Cards are stock, not overclocked.
Amd driver version is 17.7.1
Claymore version is 9.7
windows 10 x64
virtual mem is set to 4000-16000
pci set from auto to gen1
4g decoding enabled

Here are the things I tried to fix the issue;

Checked the risers, swapped etc
Clean install windows
set -gser 2 and -eres 2 and -wd 0

Those above did not help. Most of the time people are causing the problem if the cards are too much overclocked or too much undervolted so I restored to original bios rom. However I still get the error after 2h of running and windows freezing.

I am thinking of changing pci from gen1 to gen2 and give it a try with that. Do you guys think it would do any help. If anyone had issue and solved it please guide me. I am stucked with this issue more than a week now.

Thanks
