As soon as I increase the MHz from 1125 to anything above, driver get stopped !

I have 1000W power and 2x 7970 XFX Ghz Edition

The funny part is when I connect the CrossFire, first one get lower and gives me around 500 Mega Hash per sec and second GPU gives me 680 M hash per sec !!!!

And when I disconnect the CrossFire, everything gets reverse !

navidos, wait - so did you return your 2x 7970 and got two GHz edition instead?
What are your current core and memory voltages?
My card would get driver crashes as well running Heaven, even at 1050 / 1500 (manual OC) with the stock voltage.
When I flashed to GHz bios versions it would work fine on 1050 / 1500, but that's obviously also because the voltages were increased by default.

Yes I did.

I can't check the voltage on Catalyst but there was no any change there as I know.

So same thing here ! Driver issue as soonas I increase the MHz above 1125 Mhz.
