I have a 2.4c processor on the asus p4p800 motherboard. I can overclock it to 3251 I think is the highest it will go. After that it will just not start back up then after it does it says OC failed. I am pretty sure this is my memory (pc2700) that is causing this problem. But anyways when I do get it that high. I can run it for about 5 mins restart and the CPU will be 115 F So I am thinking of getting a new heatsink. Does anyone have an good ones they can recomened? I have everything that came with the processor right now
