I built a new system with following specs:
- Intel i7 3770K
- AsRock Z77 Extreme 4
- 16 GB (2x8GB) from GEiL, DDR3-1600
- MSI GTX670 OC Version
On that GPU I replaced the cooling system with a ProlimaTech MK-26 and silent fans.
The OS used is Windows 7 x64, and for some reason when I run the Performance Index test, the driver crashes over and over (and at the end resulting in a score of 1.0, since it wouldn't do anything).
I tested with current nVidia driver 310.90, and an older version 306.23
I can run Diablo 3 with maximum settings just fine, and the card would not exceed 35°C, but when I run DotA2, it runs for 1 minute, then I get a black screen, and then I have an invisible DotA2 window, which I have to kill from task manager.
I tried seriously underclocking the card (to absolute minimum that Precision X / Afterburner allowed), but it behaved precisely the same.
I also tried to change the timeout in regedit (TdrDelay), but that did not help, and I found nothing else pointing me to possibly the right direction.
Anyone know what may be happening here? The system is brand new, and all drivers have just tonight been installed.
