Hey I did the volt mod, but am still waiting on a water block so I havent pushed it very far yet, however I have a problem. My problem only occurs after waking up from sleep mode. After it wakes up, about 5 or so minutes later the video card crashes and the screen goes black. This usually happens when I'm on the internet. However if it did not come out of sleep mode and just normally booted up the card runs awesome with everything including serveral hours of crysis and such. Im running vistax64 anyone have any ideas or had a similar problem?
