Specs to the left, it is in a P5N32-E SLI(680i). I just can't seem to get this thing to a decent overclock. I can get the FSB up to about 1300, but it is unstable even there, and it seems the P5N32 needs a very high NB vcore to even POST at that(1.5v) and I think the NB is overheating at that speed because the machine freezes shortly after POST, usually shortly after logging into Windows. Plus the northbridge heatsink is hot enough to burn my finger if I touch it for more than a second. I don't know what to do. The vcore on my Q6600 is 1.5v, and temps are fine. That vcore should be more than enough and I don't think it is the problem. If I lower the NB vcore the machine won't even post. I'd like to get the damn thing up to 3.0GHz, which would be a 1333FSB, but I can't even get it stable at 1300. Is the P5N32-E just not cut out for overclocking Quads?
