    Default Pentium FSB speeds

    I'm about to get a new socket 478 CPU and wondered if the difference in price of a 533 FSB vs 800 is worth it?

    I'm considering:

    [INTEL] PENTIUM 4 3.0GHZ PRESCOTT CORE
    SOCKET 478, FSB 800, 1MB L2 CACHE, RETAIL BOX @ $324

    [INTEL] PENTIUM 4 2.8GHZ PRESCOTT CORE
    SOCKET 478, FSB 533, 1MB L2 CACHE, RETAIL BOX @ $293

    Would I experience a noticeable difference in performance?

    Thanks.

    so yanking the cpu out without unlatching it done some damage?

    What??

    As far as the CPUs are concerned, although I have a 478 (2.6) I wouldn't recommend the Prescott, and would suggest you upgrade your mobo and CPU

    (morganj): 0 is false and 1 is true, correct?

    Does your motherboard support a FSB of 800 MHz? What motherboard you are putting this into?

    True, unless the mobo supports 800 MHZ, there's no point putting the Prescott in it.

    It wont work, if the mobo only supports upto 533 FSB.

    If u want HT, then if u get a 533 CPU, u need a 3.0 GHZ + CPU.

    If u get a 800 mhz FSB CPU, (and the mobo supports 800 FSB), a 2.4+ will give u HT.

    And if u get a Prescott and use XP, you may need the patch (for some Prescott CPU's, depending on whether its one of the affected CPU's).

    If I had yanked a CPU out of the motherboard without unlatching then I would expect to replace both motherboard and CPU.

    There again I don't use Intel CPUs.

    Still sitting here with my AMD 3200+ cpu but I did have to replace the motherboard as I got little brown lumps on a couple of capacitators.

    Funnily enough I was able to replace the motherboard without reinstalling WinXPPro SP2. This surprised me somwhat as I had taken the trouble to backup all docs etc in case I needed to put these back.

    I changed the motherboard but it still worked.

    To be honest I doubt I had any other way of getting the thing out even if I'd remembered about the motherboard latch. The heatsink was stuck so firmly to the cpu that I had to pry it off with a lever.

    And yeah Elephant, I don't think it did the mobo any good, but I was sure it was damaged anyway, so the one mentioned above is the replacement.

    [edit] incidently, I reckon all my recent woes came about as a result of a power outtage, which knocked out my measly spike-catcher, and evidently buggered my ram, motherboard, power supply and cpu.

    Sometimes twisting the heatsink can break the bond holding it to the cpu, and it cant hurt to run it first before going in for the kill.

    Its a back art though, seeing as you can't see into the future (trust me on this, I tried and just got a headache) you just don't expect the heatsink to drag the cpu out of a locked socket....
