Need some advice on setting vcore

post #1 of 4
Thread Starter 
My motherboard is a p5ld2-vm asus. My cpu is a 3.2ghz ht. I managed to boot the machine at 3.92ghz but after 1 hour of prime, it crashes. Can anyone advice me on how much voltage i need to supply to make it stable?
My cpu is a prescott

Each CPU is a bit different, but I would expect that it would need in the 1.5-1.525 volt range. I believe my 3.2E @ 3.92 GHz runs at 1.5125 volts 24/7.

Raise the Vcore up slow and run prime till stable. It may not need be as high as PPL with the same chips on different boards so better to work it slow and not just pump it up!!!

Did you just go from 3.2 to 3.9 in one jump or did you increase slowly testing each change?


Did you mess with your RAM timings and speed? It is possible the error is RAM related and not CPU related. This is why it is usually recomended to change only one thing at a time so that it is easier to troubleshoot where the error lies. If you change the FSB, vcore, Vdimm, timings and speed all at once, how do you know what failed?

Still, that's a pretty good overclock for that board.
