SonDa5: yup tried various drivers same thing, and like King4x4 if i return the oc to stock all goes away.... Could it be a faulty dvi-hdmi cable ? because if the cards was faulty it would artifact even more under stress and 3d right?

I used Trixx.
Tried it with a fresh driver install too but had to lower the clocks to stop it from crashing in BF3.
Anything over 1250 and it would start to artifact.

Might try the new vapor-x 7950 bios that sapphire released again with the modded trixx.
Temps when I used it were great but MVDDC was set to 1.5 and couldn't get the memory stable over 1250.

Is memory voltage and clock the main influencing factor in VRM temp? sorry if thats a stupid question...

Hi guys, I got my hands on a sapphire 7950 dual-x last month. Its my first AMD card and I want to overclock it. I got some questions:

1. What are my limit on core and memory clock without touching the voltage on air?
2. I want to reach 1100 on core and 1400 on the memory clock, which tool should I use for OCing and for stability test?

Any help will be much appreciated . . . biggrin.gif . . . Thank you thumb.gif

My rig:
cpu - i5 3470
mobo - ga-b75-d3h
ram - 4x2gb twinmoss twister DDR3 @1600mhz
psu - CM gx550w
