celeron 566 vcore?

[fondoo]

what is the vcore by default?

1.50 v

It depends on what stepping you have.

the early stepping was 1.5, but the new stepping is 1.7

Well if you go to the intel site they also metion that the new stepping has dual voltage plane. What does that mean? Do all coppermine chips have this requirment? Do the these new chips OC better? I have my celeron II 566 running at 860 Mhz but to get it stable I have to run it at 1.85V Anyone know about the CC stepping? The default voltage for my Celeron 566 is 1.7v so it is the new cc0 Stepping.

i have my celeron clocked at 566@850.
i tried to raise the vcore to 1.7, 1.75, 1.8, 1.85, and 1.9 and still
couldnt get close to 1G. any idea why??

some chips just don't go that high, if you have sufficient "exotic" cooling and want to risk it... there is a hardwiring mod you can do to set the default voltage to 1.9v, from there the bios should let you up to 2.15v+ only do this if you have the enough cooling, as using this much voltage can easily kill the cpu...
