I have been having issues with games, mainly Crysis 2/BF3 with my Gigabyte GTX 560 ti OC. I have updated the bios for the card, and am running 285.62 drivers.
The crash is not overly frequent, but occurs as soon as my gpu spikes to 100% usage as seen with MSI Afterburner. (Gpu usually stays at 99% usage and runs absolutely fine at that). I have tried different settings with voltage/clocks but it still seems to occur.
AMD 840 @ 3.7ghz
2x4GB Kingston HyperX 1600 8-9-8
1x GTX 560 Ti
Antec Earthwatts Green 650w
If the BF3 forums are any indication, most people are experiencing problems w/ BF3....tech support recommended rolling back to the .38 drivers. I have 3 kids playing w/ 3 different cards and all having similar problems.
