Driver stuck in loop error when overclocked past certain range

[Cali3350]

Hey all. My new build - i love it. It performs so much better then my old computer that its hard to believe technology has come this far in just 2 years. However, ive run into a problem that i really cant explain, and im hoping some of you can help me shed some light.

I have a E6300 and Biostar 965PT. Both work well, and i easily run it at 401*7 all day long without any problems. Anything a throw at it, be it 24 hours of Orthos or a day long loop in memtest passes just fine. All games play beautifully and its a great thing.

If i move it up to 430*7 (or 450*7 for that matter) Orthos will run all day aswell as memtest (higher voltages but its rock solid in both) and i could run any sort of benchmarking program without challenge. The problem is when i try to play a game. Using F.E.A.R. as an example the game will just randomly freeze up completely for a few seconds with no sound, then sound will loop over itself indefinite (about a seconds worth whatever that sound is). The computer hard locks with this sound repeating and i have to force a restart. The few times i have seen the cause it reports "Video driver thread stuck in loop" as the cause. Different ATI catalyst versions seem to last different lengths of time before this happens, however they all cause this problem.

Was wondering if anyone may know what the cause is here?

I will venture a gues since I can't say I "know" what the problem is. But my guess is your pci-e voltage may be too low. In you motherboard if you can increase the voltage to the pci by lets say 0.1 volts try that. It sounds like your FSB voltage is ok since you only notice the problem. Also make sure on your motherboard your PCI frequency is locked at 100 MHz not the "auto" setting because on some motherboards the auto clock setting for PCI is not always set properly to 100 MHz. You are in a situtation now that only affects your video card which is on the PCI bus well memtest and orthos do not exercise that part of your system but F.E.A.R. does

Also have you overclocked your video card itself? Because the overclock setting only takes effect when you are in 3D mode
