Ok, I've managed to overclock it to 2.4Ghz now with a 10*240 multiplier. Voltages: 1.3750 on CPU and 2.15 on RAM. Its running at DDR2-800 (says everest when I benchmark :P) and I have the HTT muliplier at 4x. Its perfectly stable when I run 2 instances of Prime95. It seems the problem was the voltage of the RAM? 0.05V raise is sufficient or is it safer to put it even higher?
if it can take the heat, then yes. HF!!!!!
