    for the P4s
    ex. P4 1.8a means
    1.8ghz 400mhz bus (100 quad pumped) w/512k L2 Cache

    P4 1.8b means
    1.8ghz 533mhz bus (133 quad pumped) w/512k L2 Cache

    P4 1.8 means
    1.8ghz 400mhz bus (100 quad pumped) w/256k L2 Cache

    btw I don't think a 1.8b exists..just using it as an ex.

    I have a 2.5GHz 400bus at 3.0GHz. It will go 3.1 on win2K, but not XPpro.

    I want to learn more and more to see as beautiful what is necessary in things; then I shall be one of those who make things beautiful. Amor fati: let that be my love henceforth! I do not want to wage war against what is ugly. I do not want to accuse; I do not even want to accuse those who accuse. Looking away shall be my only negation. And all in all and on the whole: some day I wish to be only a Yes-sayer.

    Well, i just so happen to have an Engineering Sample P4 2.2a which has unlocked multipliers from 16x-22x. Unfortunately its the b0 stepping and i cant really get it 100% stable above 2.7ghz without going past my vcore limit of 1.6v.
    if this were a c1 stepping p4 i would easily be at 3.2 ghz @ 1.6v(in theory of course)
