    I don't know what to look for in a new board.
    what items are new for a P4?

    I assume pc 133 ram is now pc400

    What about FSB

    Don't need:
    dual processor
    expensive technology e/.g 800RAM
    network: I use a pci ethernet and router
    onboard video or audio: I use SBlive 5.1 pci, and a Radeon 7200 64 VIVO
    Also have USR V90 pci, 192 MB pc133, 30GB deskstar ATA-100

    Basically, what board should I be looking at, probably in Asus?
    don't think going to a PIII 1gb from my current 600 Celeron-a mistake-low on
    funds a while back.

    don't do anything to excess. I've never even used my Pioneer 16x DVD player
    Not gonna spend on a very best processor either. The upgrade itself is what
    I'm asking for, not any other perforamnce improvement for any speicifis
    reason. I've got a brand new 300W power supply, and the case is great, and
    happy with everything else.
    THINK I'll need board, processor, and RAm only. If I could pay less for the
    MB, RAM, and processor e.g. say $400CDN for 2.0GB, std. board, and 512 pc400
    RAM, and save a few hunred I would like to know what that board was. Don't
    know the current specs, so I can't shop. Don't think I'll need to with the
    right info, just look for the best price.
    ANybody know where I'm coming from?

    So, let us work the problem backwards. What can $400 CDN ($296 US) buy ?
    Using solely for pricing purposes:

    512MB PC3200 (DDR400) - you didn't state CAS2, CAS2.5, CAS3 (lower
    is better). Best price $77.00 US and it is probably CAS3...

    Intel processors:

    2.0GHZ processor 400MHz FSB 128KB cache (Celeron P4) $62.50
    2.0GHz processor 400MHz FSB 512KB cache (Pentium P4) $135.00
    2.4GHz processor 533MHz FSB 512KB cache (Pentium P4) $167.99
    2.4Ghz processor 800MHz FSB 512KB cache (Pentium P4) $182.00

    If we use the Celeron, this leaves $156.50, but we don't get the best
    use of the DDR400 ram. Usually the ram can be run one "notch" higher
    than the FSB. FSB400 = DDR200 or DDR266. FSB533 = DDR266 or DDR333.
    FSB800 = DDR400+. At the other extreme, choosing the $182 processor
    leaves only $37 for a motherboard. The FSB533 leaves us with $51,
    which is a pretty low target to hit. Of the other two choices, the
    extra cache buys you a few hundred MHz equivalent performance, so
    once the motherboard is selected, a faster Celeron with 128KB
    can be used instead.

    P4PE-X $77 (Official FSB800 support, otherwise a stripped down P4PE)
    P4G8X $80 (Dual channel DDR266, FSB533)
    P4P8X $89 (Dual channel DDR333, FSB533)
    P4PE $95 (Single channel DDR333, FSB533 - 2x512MB max mem cheaply)
    P4P800 $104 (Dual channel DDR400, FSB800, non-deluxe model)
    P4P800 $129 (Dual channel DDR400, FSB800, deluxe model)

    If you buy the P4P800 (non-deluxe), you can stick more memory or a
    better processor in it later. Since the P4P800 is dual channel, we
    can use (2) 256MB memory modules. With the money left, buy a better

    Budget (US Dollars) $296
    P4P800 non-deluxe $104
    256MB PC3200 (DDR400) CAS3 Infineon N82E16820200038 $41 * 2 = $ 82
    Celeron FSB400 128KB cache 2.7GHz $108
    Left over money $ 2

    (If you did buy the 2.0GHz Celeron for $62.50, you could try
    overclocking it to FSB533. See
    and the entry for P4 Celeron 2.0. That would give you a core
    speed of 2.66GHz, and the faster FSB533 would give you more memory
    bandwidth for less money. Leftover money now $47.50 US. With that
    money, you could go for the P4P800 Deluxe at $129 if you want.)

    Chances are, for the same money, you can get more kick from a
    A7N8X Nforce2 plus a Athlon XP2500+. On a Pentium system,
    overclocking is via FSB adjustment. On the A7N8X, it is best to
    keep FSB and memory clock the same - you can then crank both of
    them up an extra notch, and as well, you can adjust the multiplier.

    Budget (US Dollars) $296
    A7N8X deluxe $125
    Athlon XP 2500+ (overclock to 3200+ level with DDR400 rates) $ 85
    256MB PC3200 (DDR400) CAS3 Infineon N82E16820200038 $41 * 2 = $ 82
    Left over money ($39 leftover with A7N8X non-deluxe) $ 4

    As before, the non-deluxe is cheaper, in this case the A7N8X
    non-deluxe is $90 US, a considerable saving.

    To review all the options, start here:

    Summaries are here, but they don't list onboard peripherals:

    Oh, one other thing. The amount of +12V power you need...

    2.0Ghz Celeron FSB400 128K cache 53W max
    2.7Ghz Celeron FSB400 128K cache 67W max
    AthlonXP 2500+ FSB333 512K cache 54W max
    AthlonXP 3200+ FSB400 512K cache 61W max

    At 67W, this is (67/12)*1.25 = 7 amps from the +12V supply.

    Processor max consumption from +12V = 7 amps
    Disk drive = 2 amps during POST, 0.5 amps idle
    Cooling fans = 1 amp
    Video card = 3 amps if separate power cable

    If you have an older video card without a separate power cable, power
    comes from the other rails. Since power numbers for video cards aren't
    published, the 3 amp number is just a guess. With the older video
    card, a running system will draw 8.5 amps (Prime95 or 3DMark). With a
    newer video card with separate power, the number could be more than
    11.5 amps (3DMark). The video card only draws large currents while
    doing 3D stuff. Compare these numbers to the amps printed on the
    label of your new power supply.

    Have fun shopping,
