"HD7970 & HD7950 Results Thread - Torture Your Card, Post It Here!"

[owikh84]

I am getting bad artifacting, and fan control drops to 50% even when set to 100% all when trying to overclock at all.

bad card time to RMA?

bios is asus, and drivers are the pre certified ones (12.2)

edit: it was the 12.2 pre certified drivers. I also flashed to the MSI bios (link below) as the asus bios has poor performance as Martin said.

This special MSI bios allows my trifire 7970 to bench 3DM11 @ 1300 @ 1.29v, altho artifacts. Gaming is stable at 1.3v.

With Giga stock bios & Asus highest could achieve was 1275 only with whatever voltage.

Thus I think this MSI bios has better vdroop & more stable than the others.
