Limit of Oc?

    Ive got a 2.7 celeron, I was wondering how well this particular cpu oc's. Ive gotten up to 3.2 ghz by incrementing the FSB, but when i go 1 more mhz over 3.2 it fails to load windows, what should i try to get past this? Or can this cpu get past this? The temps are amazing at 3.2- 30 normal 38-40 under load.
    The only way i know to increase clock speed is by increasing FSB, im at 119 i think right now, is there any other ways?
    My setup consists of:
    ASRock p4S61
    2.7 Intel Celeron 478
    1Gb Corsair Ram

    Ive got this in a case w/ all the wiring taken care of as to maximize airflow, i have 1 80mm intake, a 80mm exhaust, xdream cpu cooler w/ duct, a 120mm psu fan. The cooling system seems to work wonderful, but i just cant get past 3.2
    I would love any suggestions.
    Thanks

    This sounds like a Northwood unit to me...

    I would recommend that you try upping the voltage. Just loading into Windows is irrelevant; you have to load up Prime95, 3DMark, and HL2 for a while and see how it runs.

    It is a northwood unit, i dont see any options in bios to change the voltage, its already at 1.6.

    Ive tried running prime 95, but after like 3 hours it shuts down and says it has found a hardware error, what does that mean, and how can i correct it?

    Ditto with Destruction on that one...But sometimes the mobos hardware is not deisgned to allow certain voltage changes, so you may be out of luck there.

    My RAM? What changes do I need to make to my RAM timings??

    you need to adjust the FSB:MEMORY ratio, if your mobo has the option.

    tighten ram timings (make them lower) and if the mobo won't allow higher voltages, voltmod! (physically modify the board...)

    only if his ram can't support higher speeds. personally i'd never change the cpu/ram ratio.

    Be careful! Setting the timings to low can fry your RAM!
