Try dropping your oc back to 2.8GHz or even stock and see if the problem persists, 680i + 65nm quads don't play nice when overclocking sometimes

artifacts on a stock card usually indicate memory going bad, which driver are you using? (I have that same card in my second pc)

The exclusive OCZ SPD specifications take out the guesswork and provide enthusiasts and gamers with significant overclocked performance with no manual adjustment or compatibility issues.

Is your bios compliant?? One would assume maybe it isn't. If the modules run at the correct speeds and timings when manually set then it is all good imo. As to the speed I would suggest that for ordinary "non customised" bios' that the modules SPD table is indeed programmed to 333MHz JDEC standard, the OCZ site is a little vague on detail in that respect.

Anything in the logs pertaining to the BSODs??

EDIT: You say that your temps are fine and the cpu is 30°C which leads me to ask what you are using to read your temps?

Real Temp and Core Temp (the best programmes for Core processors at present) report all four cores so I guess you're not using either of those. I ask because 1.35v vcore is a lot for 3.0GHz. You say now you have everything on auto, does that include voltages?

Have you tested the 12v rails with a multimeter?
