    P3 600b @ 100?

    Heres a new one, I'm not sure if I've seen this covered yet:

    My friend picked up a 600b (600/512/133) for a good price, and he wants to use it with his Abit BH6 MB.. The processor has a 133 Mhz bus and a multiplier of 4.5 (4.5 x 133 = 598.5) - He only has PC100 Ram, and the board is only designed to run at 100mhz bus.. If he doenst overclock it - will the processor still run as a 600, or will it be brought down to a 450?? (4.5 x 100)...

    Any help would be appreciated!

    With The new "NV" bios I believe which supports 600mhz (100 Bus Speed) your friends chip will run at 4.5X100=600... You'll just won't be able to take avantage of the faster bus speed.

    Which revision of the BH6 does he have? I think anything that is 1.1 or newer has a 1/4 PCI divider. I don't see how a BIOS update will let you run it 4.5X100=600MHz. The only way to run it @ 100 MHz FSB and the core @ 600 MHz is to change the multiplier, and I don't see how Abit managed to do that via a BIOS flash.

    Huh?

    This is what I just got back fom Intel...
    Hi, A better question is, does the motherboard support the specified voltage for this processor? Ask the motherboard manufacturer? If it does support the voltage, at 100 MHz, the processor would have a core speed of 450 MHz since the multiplier is 'fixed'. Operating this processor at 100 MHz is out of specification, even if all other specifications are observed. Operation is not supported. This is also, IMHO a waste of a good processor. Get a motherboard that can use it.
