Sapphire HD7970 artifacts and unstable

I wouldn't pay attention to that. If it reads memory usage right in MSI Ab when gaming then it's ok.

 

you have a link for the new psu?

 

This is the PSU i have in untill new one to arrive InterTech EPS-750W, and this is the one i ordered Corsair CX600.

 

3dMark 11 bench I did today at 1100/1500 and cpu at 4.5Ghz , went good, stable, but still don't understand why its showing my ram at 1333 if i manually set it in bios to 1600.

Cheers

EDIT: installed CPU-z my ram running normal at 1600
