Using a P4 with 400mHz FSB on a 533 mHz M/B

Archived from groups: alt.comp.hardware.overclocking (More info?)

hi all

I currently own a P4 1.7 Northwood 512 kb cache, with 512 SDR Ram, the
M/B has a FSB of 400mHz.

I 'd like to upgrade my system by getting a M/B that will support DDR
Ram, but i'd like to keep my P4 1.7 for now. If I buy a 533mHz or 800
mHz M/B will my processor be compatible? Might it be possible to
overclock it using the 533 setting to 2.26 gig (ie 133mHz x 17 = 2.26
instead of 100 mHz x 17 = 1.7 mHz) or have I got the wrong end of the
stick?

thanks for looking

    My P4 1.8 400 runs flawlessly at 533 for 2.4 with stock heat sink and fan.

    Never heard of a Northwood 1.7, so it's likely a 1.75V 256kb cache version
    limited to ~2.0GHz (Williamette?). There's nothing of the sort on Intel's
    s-spec page for P4's - all 1.7's are 256kb, 0.18um (none are 512kb,
    0.13um)...

    Unless Intel snuck out some undocumented processor that can't be a
    Northwood as the slowest (documented) Northwood is 2 gig.

    yep, your both right, I double checked and it's only got 256bk of L2 cache.

    so I'm stuck with 2 gHz at best?

    were the 1.6A and 1.8A designated as something other than Northwoods, by
    Intel?

    Well, no, I wouldn't say you're necessarily 'stuck' with 2 gig. A look at
    the overclockers database indicates that 2.2 might be a reasonable target
    and there's even one posted at 2.5, supposedly with the stock Intel cooler,
    but you can't always trust what someone claims. The average was about 2.1.
  7. Archived from groups: alt.comp.hardware.overclocking (More info?)

    Well, sad to say, what you have is not a 'Northwood' Pentium 4 (the one
    with the 512 KByte L2 cache), but a 'Williamette' Pentium 4 with a 256
    Kbyte L2 cache and a 0.18 feature size rather than the 0.13 feature size of
    the 'Northwood'. It is not worth spending money trying to upgrade a system
    and and still use that CPU, especially if you intend to overclock ( a
    'Willamette' Pentium 4 is VERY limited in top clock speed, and the smaller
    L2 cache is a real bottle neck.)

    You are in the position of needing to replace the memory, CPU, AND
    motherboard to get back on the step by step upgrade path. Since ANY
    reasonable upgrade is going to require new memory and a new motherboard,
    that is certainly the place to start, but don't let the compatibility
    requirements of your present CPU limit your future path. A 'Prescott' 2.4
    GHz Pentium 4 currently has the lowest price among Pentium 4 CPU's (a
    'Northwood' 2.4 GHz and a 'Prescott' 2.8 GHz CPU are about the same price, ~
    $175 US [both with 800 MHz FSB.]) You could expect to spend at least $175
    US for an overclocking friendly motherboard and 512 MBytes of generic
    PC3200 DDRAM.

    I have a 1.8 Williamette CPU which I run at 1.98 (4x110) and it is fine and
    stable. I have tried to go above 2ghz but I get an instant crash (using
    Easytune). Something thats been bothering me is my manual says the board is
    a 400FSB but it has FSB settings all the way up to 133. Does this mean I can
    run a 533FSB CPU? The max multiplyer is 24 and the board is a GA-8ITXE with
    an i850 chipset.
    Any feedback greatly appreciated.

    WRONG. Williamettes came in both pinouts.

    Depends on the motherboard. If your RDRAM is PC800, it will not overclock
    by 33%, so you would have to be able to use the async memory setting (5:4
    ratio for FSB:memoryclock.) In fact, memory speed might be your limit even
    with a .200/1.8 = 11.1% increase for PC800.

    Thanks for the info. The ram is PC800, i'll play it safe and just keep
    looking out for a 2.4 with 400FSB. Oh and the CPU is 478 pins.

    A Pentium 4 2.4 GHz with a 400 MHz FSB is $180 US at
    http://www.zipzoomfly.com .
    Yeah, I know it is a flaky name, but they were once called 'googlegear', and
    I think google.com complained. I've bought memory, motherboards, CPU's, and
    hard drives from them and had good experiences.

    Then you can get THAT Pentium 4 2.4 above 3 GHz using the 3:4 ratio and
    PC800 overclocked only 12.5% even at 3.2 GHz, so the memory speed of your
    current PC800 will likely not limit your CPU speed.

    I have a Pentium 4 1.6A running at 2.4 GHz using using PC800 and that
    method. Basically the FSB is running at 4/3 X 1.125 X 100 MHz X 4 = 600
    MHz, while memory is running at the equivalent of an FSB speed of 450 MHz,
    just a 12.5% overclock.

    If you are using win98 classic, you are limited to speeds less than 2.2 GHz.
    At that speed it will refuse to load a driver due to a divide-by-zero error.

    Only if you don't get the patch for it. There is a patch for that just as

    Great info Phil, thanks. I've saved it for future reference when I do
    finally pick up one of these critters. I'd ordered a 2.4 400FSB CPU from
    PCBuyers.co.uk for £70 yesterday but they called this morning and said
    they're out of stock. $180 US is tempting but out of reach atm at over
    £100. I'll keep a look out for a 2nd hand one.

    Incidentally, do you think that a Celeron 2.4 will out pace my 1.8
    Williamette running at 1.98 and how are they for overclocking? They are nice
    and cheap at about £50 but will it give any significant boost?

    True, there is a patch but getting it requires a call to MS and may involve
    a trouble-call fee. I heard the patch only works for two weeks anyway so I
    did not mention it.

    That Celeron and the rest of its family has only a 128 Kbyte L2 cache, and
    thus has a severe limition on its performance. You'd be much wiser to look
    for a 'pulled' Pentium 4 2.4 GHz with a 400 MHz FSB. The price and
    availablity of a new 2.4/400 is likely because they are no longer made (my
    guess.)

    hi Phil

    Thats the conclusion I've come to myself, so I've managed to justify a
    new computer to myself!!!

    2600 Barton
    Ati 9700 SE 128 MB
    512 DDR Ram
    ....and while I'm at it a 160 gig hard drive

    You can find it on download sites, although not easily.

    Sounds like an old wives tale.

    What do you mean bt "Pulled"? I'm back in the OC game and assuming a
    2.4/400 is a good candidate?

    thx

    "Pulled": removed from an discarded computer system; used. A Pentium 4
    2.4 400 MHz is more likely to be found used that Pentium 4 CPUs with a
    faster clock speed and/or faster bus speed.
