Gigabyte HD7950 artifacting

Hi, my friend and I just built a new system and everything seems fine except upon installing the graphics card drivers, I get a significant amount of artifacting on the screen. I've tried catalyst 12.4,12.6 and 12.7, as well as the gigabyte drivers from their website to no avail. The card has a factory overclock, up to 900mhz on the core, is it possible this is the cause and it is just a dud card?

System specs:
SilverStone ST60F-P 600W PSU 80+
OCZ Agility 3 240G SATA3 SSD
Cooler Master Hyper 212 EVO w Transparent 12cm
Gigabyte ATI HD7950 3GB GDDR5
G SKill 8G(2x4G)DDR3 1866Mhz PC3-14900(GS-F3-1866C9D-8GAB)
Seagate SATA3 2TB 7200RPM Barracuda 64mb Cache
Asrock Z77-EXTREME4 Z77/4 x DDR3/2 x PCI-E3.0/4 x SATA3/6 x USB3.0/HDM
Intel Core i5 3570K LGA1155 CPU 3.4Ghz 6Mb Cache Ivy Bridge

  2. i recently had a problem with a gigabyte gtx 560ti card,it was a factory overclocked card and i had artifacts(lines on screen in game) and it would crash and restart my system,i found it was more stable when i reduced the core clock,i returned it to gigabyte twice,but the problem still experience with gigabyte warranty was not good..after this i had to request a replacement card(gainward)from where it was purchased,this card has been fine,no problems,return it for warranty claim
  3. Sounds like Gigabyte don't pick their factory overclocked cards very carefully - return it.
  4. You are probably going to have to return the card, but before you do that, try an absolute clean install of the drivers. Use atiman uninstaller to completely remove the drivers, and then try a fresh install of 12.6.
