I'd advise you to listen to Werewolf & Glucos before you RMA your card. The other issue is that unless you did a full uninstall of all AMD's (GPU) drivers and apps you could have some stray bits of AMD's code still attempting to run. Always uninstall a vender's drivers & hardware before installing another.

I realize this is a bit extreme, for normal users, but when I'm doing hardware testing & engineering, and I need to change a major component like a MB or GPU, I'll start with a fresh OS reload just to make sure I'm not seeing any impact from orphaned bits of code.

Graphics cards can have defects, sounds like yours is unstable, driver crashes and recovers but starts running at "safe" (really slow) clocks.

Maybe try another driver, test a few other games. If you still get the problem return the card to where you bought it and get a new one.

Its most definatly the GPU having issues while under load. I have an old Radeon 5870 and an old GTS 8800 and both cards did it after a while so its not confined to one brand. My current card hasn't exhibited this problem (thank god... 400 bucks isn't what I would spend on a paper weight) so I think its just the luck of the draw.


Send it back and get a new one.

Using the MSI 660 card TwinFrozer, and I have been experiencing the same issues.

The black screen seems to indicate that the card powers down (fan stopping, MSI afterburner showing drop in power usage), Alt-Tabbing for a few seconds to desktop resumes full FPS.

On my card, I think I have pinpointed the issue, being a faulty heat probe (car registering 60°C max at full charge, which strikes me as odd).

OP, if I were youI would follow the advices of returning the card for an exchange (which is exactly what I'll be doing this week).

60c under full load is normal depending on your case setup, also... unlike most cards ... Your twin frozer exhaust heat inside your case so if your lacking case cooling then that is why your card is glitching out from overheating. And one other thing make sure your power settings are set to preformance and not adaptive.... this will cuase the drop in power usage and your fan to slow to a crawl.

It is most likely a bad card. What nvidia doesn't tell people is that 660 ti's are actually 680 gtx that as a bad portion of silicon. They had a huge mess with the 680's when they first came out and had a loss of 75% or something on the production run, so what they did was disable certain areas of the card then rebrand them as a lower spec card, which is why on paper the 660ti is better than the 660. Although most of these cards run just fine with the bad portions disabled (think those amd 4 cpu chips that only ran three cpu's because one was bad) sometimes the boards have other quirks or issues. I would just return/exchange now before it really cooks itself.

This is most likely the problem.... Although the 660's are good cards you are basicly buying a gimped 680.

AMD and Intel have both done something simular with the old Celeron's and triple core Phenom II's.

The die is ruined and they can't stand to just trash it.. so they rebadge it and sell it as something else.
