Depending on which version of the E6600 you are running, 45nm or the 65nm version, you appear to be running your CPU overclocked at 3.4 GHz which can easily cause the problems you are having.
The 45nm version runs 1066FSB at 3.06GHz while the 65nm version runs at 1066FSB using a different multi to run at 2.40GHz. I'm not sure what the default multi is for your CPU or even which version you are running but this info would be helpful. Either way you need to return your CPU to default 1066 FSB using the default CPU multi before you attempt to fix this problem.
You might want to also take great care in setting up your memory per manufacture specs, including memory voltage, timings and memory speed. Your pc2 6400 memory is only made to run at 800Mhz using 5 5 5 15 with 2T command rate with your CPU at default settings if you want stablity.
This part of the forum isn't really about helping people overclock. We have another section for that if you need help in that area.
