    Even though ya get a mobo with intergrated video be sure that it has an AGP slot so ya can upgrade the video later. :smokin:

    I sure do, I did it for him....... But compaq models are all different, and he had an AMD processor... What is your Processor brand, and what is the Compaq model number of the computer?

    Well there are two way to do vcore on a socket 370, solder a resitor/pot onto the volatage regualtor, or tie some CPU pins together.
    You have to search there since i dont know the specifics for your mobo.
    try searching for the pin trick on a cusl2 mobo
    should work fine since it is a proc mod.
    The defualt Vcore will be whatever the defualt is for the celeron.
    I did a regulator mod on a K7S5A, it really is easy (went from 1.65vcore to 2.4 :D )
    Again ask around to see what a safe vcore raise is.

    as for the turbo PLL :D

    most PLLs send separate clock signals for the PCI RAM and CPU on different pins.
    The idea there is to get an outside clock generator (quartz usually) and feed a higher clock onto the CPU line.
    goto CPUcools website and use the guid to find out what PLL you have.
    then you might want to goto the PLL's manufacurus website to find a pinout diagram and the white paper.

    then you will have all the info you need
    Id advise much searching on this though, as I havent done it...Yet :)


    if both mods go well
    I wouldnt be surpirsed if you hit 900-1000 range


    BTW you could just get a new mobo, but nowhere near the fun :)

    EDIT I see the PLL # you gave
    im gonna go dig a little

    found the prob

    the Bios uses fourbits to set the FSB
    2 are programmible
    2 are from setting on pins

    look at the table on page 3 of the spec sheet
    looks like your gonna have to find a way to set FS0 the a 1 bit
    then Soft FSB should work from 100 to 112 mhz
    ill see if i can make a setting for softFSB to be able to work from 66 to 75 just to see

    wwilliam54... you use too many abbreviations! i'm not an amatuer ... but i'm not that experienced! ... but i'll look around for what you say.... i already have the specs on my pll-ic.... i just don't know what i'd have to do to it. I'll keep working tho

    The system did become less stable, but not alot less stable. Two or three restarts a day and you might not even crash! :D

    So it is at least is possible, but don't try it without a better hsf.

    After about a year of use in this setup, however, the PC started to degrade, and finally when the comp was 3 years old, and had been overclocked for a year and a half it finally stopped booting. But no big loss, as it was a compaq (with a K6) from day one. 3 years was far longer than expected.
    oh yeah
    forgot to mention

    that should have been pretty easy
    even on OEM boards most socket 7s had multi and FSB jumpers

    *creack neck and smiles

    get softFSB and import this
    Pll data file for Soft FSB

    I hope it works
    if so at least it get you to 718mhz
    im gonna chew through the data sheets some more later

    yeah, i know... and my motherboard even has the labels for the jumpers that should control the fsb..... but i can't find the jumpers themselves! it's quite silly.

    and the only problem with cutting pins and soldering wires is that if i wreck something... i'm f@#ked. cuz i don't have money for a whole new computer. and i most certainly need my computer for school. :geek:

    eventually i'll save up enough money for a new mobo.... i still think i should be able to communicate with the pll-ic through softfsb or something.... i think that the ic may be a specific version that doesn't want to be communicated with! :snip:
