I've been looking at tom's hardware for a good while, but never needed anything answered until now, so I signed up Anyways, I've been working on overclocking my AMD Phenom II x4 965 black edition all day (my first cpu overclock, btw), and it's giving me hell when I try to get to 4.0 ghz. I've gotten it to 3.9 and have successfully run prime95 stable for roughly 2 hours and still counting as I write this. It's set at 1.5v and temps haven't gone higher than 58C, running an average of around 56C. However, when I get it to 4.0 ghz, it shuts down after no more than 10 minutes of prime with the max temp at 60C. I really wanna get to 4.0 just to have that satisfaction in the back of my mind and to help get rid of the bottleneck on my gtx 670. Does anyone have any suggestions as to how I could get this extra 1 mhz without breaking 62C?
