I just overclocked my 4890 in ccc with ati auto tune, my fan was set on auto and its a non reference design card made by VTX3D, auto tune overclocked it to 940 on the GPU and 1040 on the memory just 10 Mhz shy of the max limit on ccc.
when i try to run the crysis benchmark the driver crashes and windows 7 says your driver has recovered. every time i try it dues the same.
is it a driver issue ? ( the only reason im saying this is because i just watched your recent video on youtube and i think the same thing is going on with my driver )
