Gigabyte 7950 Artifacting MSI Kombuster Stock Speeds?

[elayman]

I just got a Gigabyte 7950 and tried to run MSI Kombuster Furry and Tessy Test (GL4) at 2560x1440 (native) resolution (AA: Off) and when it first boots up I see 2-3 artifacting episodes and then it runs fine for the rest of the test (currently on 10 min of second run).

I am at stock speeds - 900MHz core, 1250MHz mem, VDDC: 1.090V

It holds at a steady 53*C and never hotter.

Any ideas? Did I get a bad card - what other tests can I run to confirm?

What version of AMD's drivers are you running? Sounds like the artifacting may be happening when the card switches power states and ramps up to full clock speeds.

I am running driver 9.2.0.0 according to device manager.

EDIT: Forgot to mention I had previously a GTX580 in this computer - recently died and I put the 7950 in without connecting the pc to the internet and I uninstalled all NVIDIA drivers, then installed drivers for 7950.

Do you think I should reinstall windows? I don't want to but will if you think it will help.
