What is possible to do with a P2B rev. 1.12?

  1. I might be buying this one, but I'd like to know what I can put in in
    regard to the CPU speed etc.

    It will take a 1GHz P3 (either directly as a Slot 1 or a S370 via an
    adaptor) without any problems. I personally would avoid 133MHz FSB
    CPUs, the board isn't really designed to run at that speed (but I know
    there are people who have overclocked it OK).

    I have three P2B-S rev 1.04 systems running 1A Tualatin Celerons @
    1.5Ghz (150mhz FSB) on Slot-T adapters, very stable. They'll also run
    P3-S 1.4s @ 1575Mhz - and the extra processor cache on the P3s gives a
    huge performance boost (but not worth the outrageous price).

    P2B rev 1.12 has the same voltage regulator and clock chip as my P2B-S
    boards, so should be just as capable :) If not, at worst it will be
    stable at 133Mhz FSB - I've never met a P2B series board that wasn't.

    Memory tends to be an issue for P2B boards at 150Mhz FSB, but
    Crucial/Micron 256MB PC133 CAS2 DIMMs will usually do CAS3 @ 150Mhz. You
    need Corsair PC150 to get CAS2 @ 150Mhz.

    It is worth mentioning that the BX chipset of the board sets a limited
    range of agp-dividers. The board P2B retains divider 2/3 for agp all
    the way up from fsb100.

    So at fsb133 the agp is overclocked 33 % and at fsb150 50%. With most
    gamer graphics 33 % can be accepted, but 50% demands more carefull
    selection of a suited card.

    It is indeed best with some fast running ram !

    best regards

    Thanks. That was a serious omission on my part.
    Indeed - it's unusual to find a card that misbehaves at 89Mhz, but
    100Mhz is a much greater challenge. All my 150Mhz FSB systems are
    running Asus cards with nVidea chipsets - ranging from TNT to GF4 - with
    no issues.
    Agreed - ram is the bottleneck on P2B/Tualatin systems, so maximising
    FSB and memory timings should be the goal.
