Asrock Z77 Extreme9 + GTX670 driver crash

Hi Guys,

I've been lurking here a while, as I found it a fairly good resource when I was researching my new PC build, and now I'm hoping your knowledge will help me solve a tricky problem I'm having with my rig.

The symptom is very bad stutter (1-2 seconds stall, 3-5 seconds playable ad infinitum) that happens after a NVidia driver crash (error code 14). The problem only seems to occur when I'm running SLI, and sometimes doesn't happen at all in a 2-3 hour session but other times constantly. It doesn't appear to be heat related, as it will happen even when the cards are running at 60 odd degrees. The rig also seems to perform worse in SLI than it does running on a single card.

I've tried swapping cards between slots, and running both cards solo, and the issue occurs only in SLI (at least it hasn't happened after several hours on either card). Like I alluded to above, I seem to getter better frame rates running a single card than SLI but have only tested in World of Warcraft as I'm just beginning to migrate my console gaming to PC after getting kicked out of the lounge and WoW is all I used to play... :P
