I changed for new amd official win7-crimson-relive-beta-blockchain-workloads-aug11 driver and patched with atimdag-patcher 1.4.5 (bios modded only mem straps),
Claymore 9.8 crashing at start (just after listing cards and "POLO/SOLO version" caption, in log after "start building OpenCL program for GPU 0..").
It crash with stock settings or changed with OverdriveNTool 0.1.3....
Have anyone similar problem? Is that driver problem, claymore problem, other problem? was working before - 5x rx480, win7 x64
I had the same issue, I had to use DDU then reboot install the BETA Driver and then reboot, then pixel patcher then reboot again, after that it worked fine,
I did found one PC hang after 2 hours but this is quite normal for me because it always happens after I changed stuff, restarted again and will see if it happens again.
also use afterburner BETA 16 within settings make sure Unlock voltage control is ticked and next to it select third party, that's if you use claymore for undervolting.
