CPU upgrade for P4B266

Archived from groups: alt.comp.periphs.mainboard.asus (More info?)

Hi,

Can an Intel P4 2.4 , 533 Mhz bus speed CPU be used in the P4B266
motherboard which is 400mhs fsb?
If so will the performance be the same as a P4 2.4 400mhz cpu?

Many thanks
SSR

    All the processors listed are FSB400. Judging by the cache,
    it is possible some of these are Willemette and some are
    Northwood.

    There is nothing here that looks like Prescott or CeleronD.
    Both of those kinds of processors use "90nm" silicon
    technology. You want 0.13u or 0.18u silicon technology
    (Northwood and Willemette respectively).

    There is a 2.2GHz Northwood on this page ($149 OEM, no HSF):

    http://www.newegg.com/app/ViewProduct.asp?submit=property&catalog=343&propertycodevalue=0,%200,%203308,%200,%203221,%200,%200,%200&minprice=&maxprice=&mfrcode=1157&DEPA=0&InnerManu=1157

    If you want to "live on the wild side", do a search here
    on the two terms "P4B266" and "533". People do use FSB533
    processors, but remember - no Prescotts or anything with
    90nm in the details. These will be Northwood 0.13u processors.
    Likely, whatever advert you are looking at, is for a
    Prescott. Northwoods are getting hard to find.

    Another route, is to take a 1.8GHz/FSB400 and overclock to
    FSB533. You can look here and see how overclockable they are:

    I'm not certain, but if you want FSB533, and the board offers
    1:1 as the lowest ratio for RAM, you'll need at least PC2100
    rated RAM (or faster).

    It´ll work. Pay attention to the CPU:MEM divider. Up to FSB 132 you can
    choose a 3:4 ratio. Higher and you should use a workarround ( Google for
    it. ). In my experience, the chipset is stable almost up to DDR 400.

    Thank you Paul and Nfar.

    My overclocking knowledge only extends to selecting the higher speed in the
    bios for this motherboard - I have a 1.6mhz running at about 2.1.

    I am into video editing and I have optimized everyithing I can with the
    harddrives (4 harddrives, one for system, one for paging file, the other two
    for video source and rendering, each on a separate ide channel only the
    system drive sharing with the dvd writer)

    I figured the cheapest upgrade would be to throw in a 2.4 which would give
    me about 3mhz using the bios method.

    But there aren't too many many 2.4 400fsb cpus around anymore so that is why
    I was wondering if a 2.4 533 would work. But I guess I have some climbing up
    the learning curve to do so thanks for the links to start me off, I better
    do my homework.

    SSR,
    Sounds like you're currently overclocked using a FSB=133 (533 in P4
    terms.) Installing a 2.4/533 CPU would net you a 1.8 GHz CPU at FSB=100
    (400 in P4 terms) or 2.4 GHz at 533. Your board will be lucky to run the
    2.4/533 chip at the rated speed. You will not likely be able to overclock
    it at all.

    If you really want to keep that MB, definitely try to get a P4/400 part so
    you can overclock it using a 533 FSB.
