Alrighty, heres the problem.
ANY game I play crashes within a certain time frame.
Age of Conan - 3-5 mins after I log into a toon.
Crysis - 30-45 mins of play.
COD4 - 10-15 mins of play.
If I Alt+Tab to the desktop ill sometimes have a notice on the toolbar saying that the display driver has crashed and vista recovered it. Other times ive had it completely crash and my screen is very torn and pixelated. Ive had one BSOD also, nvlddmkm.sys was the reason for the crash/reboot. This is tried both in SLi and not in SLi, both crash. Ive also tried to switch the cards around and reseat them, same effect.
Now I know im not the only person with this problem, Ive seen a few other post on scattered forums. But not much is said about it. Maybe because no one knows?
People blame overheating of the GPU. I use eVGA Percision and GPU1 idles at 42 and GPU2 at 40-41. I'll monitor it during the crashes and its only its barely even heating up. GPU1 gets about 51-52 and GPU2 get 49-50, So its not heat. Some say PSU. I used a PSU calculator and it said a 650W would run my rig, ive got 850W. Memory, I ran memtest overnight, while I slept, and it came back with no errors. The OS, alot of people are completely fine runing a 9800GTX in XP and Vista, but not 64-bit. Maybe lack of 64 bit support? Lastly, drivers. Alot of people are saying that the 9800GTX is still kinda "new" to the drivers that are currently being released and they will be many bumps in the road before a solid fix.
The reason I posted is to see how many other people are having this problem that have similar rig specs. Or if anyone has come up with somewhat of a solution to make it partially stable.
try the previous driver and see if its better. the card IS new and nvidia has a bad track record with vista.
When you crash, does the screen just go black?
if its a new install and you have nothing to do, you can try to disable the driver recovery. It activates when it thinks the card has become non responsive and resets the driver. IMO it more often then not just crashes trying.
