I'm having an issue with overclocking my Asus GTX560 DC II OC. Using GPU tweak I OC it to 950/1200/1900 on 1.087 volts. During load the temps reach 56C Max with the fan on 100% yet sometimes after 2-3 hours of gaming my GPU will start throttling down the voltage and my GPU usage will spike to 99% where before this happens the Max the.usage reaches is 87%. This causes low FPS and stuttering. It also freezes for about 3 seconds and/or the screen goes black before returning to the game. However, both times this has occurred I was using the new nvidia beta driver 290.53. I have not had this occur while using driver 275.33 and gaming for 3.5-4 hours.
Its not an overheating issue and I'm not getting artifacts/display drivers failing like an unstable overclock would produce. Any ideas of what could be the.culprit? I'm thinking driver?
