I'm not experienced a lot in overclocking so I have behavior that I don't understand and thats stopping me from overclocking more.
Start from the beginning i had a 700w ocz power supply. When I overclocked my e8400 cpu to 3.6 and my gtx 260 core clock to 680 I was stable when running gpu bencmark but while gaming my coreclock was randomly getting down and my fps was down until I restarted.
After some search I understood that my gpu drived was crasing when my cpu was under heavy load. So I used prime95 blend test and kombuster at the same time and my driver crashed always until I got my gpu core clock to 640 mhz. That was desapointing, but I was sure that it was a power issues.
So i changed my psu ( that I tough was really enough before these incident) to a high current pro 850W.
Received it, mounted it and with prime 95 blend test at the same time as kombustor I can get my gpu coreclock to 700 mhz.
But if I do a intel burn test paired with kombustor the driver crash.
Am I testing too much? Is that something i'm missing?
E8400 3.6 ghz with 1.2v under bios.
I would like to push it to 4ghz but for stability in 100% cpu + 100% gpu i would have to push my gpu not near as far as now.
Sorry for the long post and the bad english ( not my first langage )
