I have two P4C800-EDLX motherboards, one is Rev.1, the other Rev.2 . I just flashed them both to the 1024.001 Bios, but when I go into the Rev.1 motherboard, I get options for up to 1.9volts...

Waaah? Could someone explain this to me...? I'm wondering if that is possible to give 1.9 volts through BIOS, I've never heard of any P4series giving more than 1.6 without the Vcore mod.

Left is Rev.2, right is Rev.1 .

I have had P4C800-E Deluxe before. Don`t know the revision, but in BIOS were the options up to 1.95V but the max Vcore that the MoBo booted was 1.6V, but using AiBooster could increase the Vcore on Prescott to 1.9V.

AI Booster eh? I'll have to look into that later tonight for my Dothan.

on the Dothan max is only 1.6v and on Northwood you get 1.9v

Hmm, must be 1.9 max for Prescott then, because I've no Northwood here.

When I set WR for Prescott SuperPi i have set 1.8V on mine PrescottE0 with AiBooster, because BIOS boots only with 1.6V max

Strange, AI Booster works fine on my Rev. 1 motherboard, but on the Rev. 2 motherboard with the Dothan it crashes with the errors

"Access Violation at address 0048DCBD in module "OverClk.exe". Read of address is 00000010."

"Division by Zero."

WTF BBQ?

Go to Control Panel -> Regional and Language Options -> Regional Options -> Customise .... and change the decimal symbol to .
It worked fine for me

(My comp is down ATM so i can't check it)

Does it work on P4P800-SE as well?No. I tested it : whenever you set 1.6V+ system freezes, but it works on P4C800... series.
