Vcore question

post #1 of 2
Thread Starter 
Well after reading these forums over, and over I finally got to overclocking my Prescott P4 524 3.06 ghz to 3.3ghz. I am taking it slow using speedfan to monitor the heat. Looks like at full load 40c, and idle around 28c. So I must have room to grow. I have a Biostar P4M80-M7 mobo, which I really need to upgrade. Got to move onto to PCI express instead of this AGP thing.

My question is my vcore is 1.34 right now, and I am not real sure where to change the value for that in bios. What should I be looking for. Should I raise it at all if everything is stable?

Also wanted to confirm some info from the great guide that got me started

Spread Spetrum – ‘disabled’ (I should disable this?)

“Initial Display Adapter†(since I have an Nvidia 6800 AGP card this shoould be set to AGP?)

Great site, thanks for any responses in advance

That's a pretty old motherboard, and may not support the changing of the Vcore easily from the BIOS. It may be a soldering job.

That's a pretty big overclock for a Prescott, and although those can hold around 50-55C, I don't think you've going to get any more juice out of that without a better motherboard.

If you can't see Vcore in the BIOS, anywhere, not even greyed out, then it must not be supported on the motherboard. Check the manual

If you REALLY want to put up the Vcore, search Google for a Vcore raising soldering guide for the particular motherboard - that is, if it doesn't support BIOS.
