I can't boot with FSB higher than 125 MHz w/ MSI 645 Ultra !!

Yes, that's right. I have MSI 645 Ultra-C and P4 2.0a. When I set FSB higher than 125 MHz and restart, computer turn monitor in suspend mode and I can't do anything. It also blocks power and reset buttons, so i must unplug it and reser CMOS !! Anyone knows where is the problem ?

Um, you probably hit the ceiling for your 2.0A P4. Not all P4 CPU's get to 3 GHz you know!

Ok, I think i found a solution. When I unplugged all devices from USB,

the computer didn't boot only at 140+ FSB (which is 2800 MHz and I

think that's limited by stock cooler).

And I want to do the P4 thermal diode calibration process, but I don't

have thermometer with sensor on a wire. Can I use normal temperature

meter?

Or if someone did it with MSI 645 Ultra, plz post results.
