    U/C FSB x Higher multiplier vs. Default FSB x Default Multiplier

    I got my K6-2 here, and until i get a fan with heat probe, i'm not touching the voltage. =)

    So:
    Does underclocking the FSB and overclocking the multiplier result in better overall system performance than default FSB x default multiplier.

    (K6-2 500 case example)
    E.G
    95mhz FSB * 5.5 multiplier = 522.5mhz
    V S
    100mhz FSB * 5.0 multiplier = 500mhz

    Cheers for you input!

    Increasing the multiplier will give you an increase in CPU clock speed but not much else. On the otherhand, overclocking via FSB increases improves CPU performance, disk sub-system I/O performance, graphics performance since everything runs on a faster bus. Therefore, clock for clock, overclocking with the FSB brings a greater performance boost then increasing the multiplier.

    I think you missed the point of the question, S-Klass:

    Will an UNDERCLOCKED FSB and an OVERLCOCKED CPU multiplier be faster than a NORMAL FSB and NORMAL multiplier?

    Cheers for rpelying anyway,

    No it won't. Unless you can ramp up the clock speed significantly you won't be able to make up for the overall loss in performance from underclocking your FSB. Remember the FSB is the backbone of your system. Everything depends on the FSB in a certain way. The multiplier can only affect the CPU's clock speed.

    OK cheers.

    Managed to get SoftFSB to work anyway, so now (don't laugh...) I got an FSB of.... 103mhz! Yeah!

    516mhz processor. You're jealous? Knew you would be.
