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). 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
same problem for me but stock cards, same driver 17.7.2, no overclocking
ok on 3 cards , but crashes with 4 at the same moment.
don't know why...
put the stock GC bios or try on 3-4 cards ?
