Upgrading a Compaq PII-450

    An out-of-town family member has a Compaq Presario purchased in
    December 1998. It's a tower and includes a Pentium II 450 processor.
    It has the standard 128 meg of RAM the system came with. Everything is
    standard as it was installed by Compaq at the factory. I don't have
    the exact system model number, but maybe someone here can nail it down
    with that info. :)

    First off, they are not wanting to buy a new system. But they asked me
    to help them with a couple upgrades.

    1. I'm going to increase the RAM from 128 meg to 384 meg (the max the
    system can hold). Since you all are Compaq experts, what type of RAM
    do you recommend for this system? I don't have it in front of me, but
    I'm hoping the system includes 1-128 stick and not 2-64 meg sticks of
    RAM. Does anyone have this system that can confirm what came with

    2. I'm also going to add an internal CD burner. Will any CD burner do
    the job or is there something special I should look for? Will I need
    any special cables, racks, etc. to install it?

    Thanks in advance for your help and advice.

    Take care,

    We'd need to know the model number to know about upgrade possibilities.
    Several 5600 series models came with PII 450s. Possibly one of them?

    If it is a 5600x, then it likely has one 128MB stick of PC100 and has three
    total slots. With the latest BIOS, it will accept three 256MB
    single-density DIMMS (SINGLE-DENSITY!).

    The burner will work fine. Jumper it Cable Select.

    The computer is a 5660. Where is the best place to download drivers
    and the latest bios for this machine? I plan on upgrading the machine
    to Windows XP.

    If I was to buy the memory from Newegg.com, what 128 mb modules do you
    recommend. Please provide direct links if possible. I just want to get
    what will work properly with this system at the cheapest price.

    Personally, I'd buy it from www.crucial.com Their configurator will ensure
    you get the right memory.

    XP will run, but not very well. I run it on mine, but only for the kids and
    even they hate it.

    Tom, you sound knowledgeable about the PResario 5600. I have the 5600
    and would like to upgrade more than just the memory. Am I able t
    upgrade the processor or clock speed as well.

    Thanks in advance.

    The Presario 5600i motherboard accepts Slot 1 processors operating at 2.0v with
    a 100MHz Front Side Bus (FSB). The fastest 2.0v Slot 1 processor is a Pentium
    III operating at 600MHz. Intel made several models of Slot 1 P3 processors
    operating at 600MHz. You do not want one with 133MHz FSB or 1.6v.

    The other choice would be a pricey PowerLeap kit which would allow installation
    of a 1.4GHz Celeron processor. There are less expensive adapters similar to the
    PowerLeap, but I can't comment on how well they work with low voltage
    processors. With any of these fast processors, there is the possibility that
    the motherboard BIOS will not allow the system to boot... Ben Myers

    I can't imagine spending the money to go to a 600. It wouldn't be enough

    The 5600i will support, with the latest BIOS, 3 256MB Single Density DIMMs
    for a total of 768MB.

    That does make a difference. I run XP on my two (450 and 500) and it runs
    OK. Not speedy, but OK.

    Agreed. A colleague of mine way back when in the trade press said that if the
    speed increase is not double, you won't notice the difference. I guess I would
    put in a 600 if I could get it for ten dollars or so.

    For most users, a memory upgrade would give more bang for the buck than a bump
    from 450 to 600... Ben Myers

    At Compaq Customer Communities(gone by now) there was a detailed
    instruction (and discussion) on how to upgrade a PII/450MHz CPU(mobo
    440BX) with an ordinary Pentium III CPU 1Ghz Slot1 SECC2 for FSB 100MHz.
    It was a bit technical, but not too hard even for someone not too
    tech-savvy. Had to do with some adjustments to the Processor Goal Post.
    (I remember this well because I was in the process of upgrading my
    Presario 5686(440BX; Slot1 CPU450MHz; PentiumIII; FSB100MHz) to Slot1
    CPU1000MHz. Has worked great for some years now in spite of the claims
    from Compaq that 600MHz was the maximum.)

    May be the instructions have survived somewhere else? You could try
    Good luck.
