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
