hi, i replied to your private IM with my settings. i also had much higher overclocks with 2x1gb. i was around 3.3Ghz on 2x1GB but when I went to 4x1GB my max 3.0 Ghz. I think it's the northbridge to be honest. The northbridge and the ram are almost painful to touch. In fact, I was only able to get to 2.8Ghz until I rigged a 120mm on low RPM to blow across the ram and chipset. The chipset being farthes away from the fan is not being cooled as much as I like. I was able to squeeze out another 0.2Ghz to 3.0. Just to be sure it was the fan, i disconnected the fan and ran orthos and it chocked within 5 minutes. Putting the fan back on, memtest and orthos ran fine over 8 hours each on the same setting. I'm thinking about getting a smaller CPU HSF to replace my Ninja so I can use an after market HSF on the northbridge. by the time I do that I could be 60% of the way to buying an e6600 with a higher multiplier. choices, choices ...
