    Post I need help overclocking a PII 400

    I have a PII 400 with 64 mb ram, and a Abit motherboard. I'm having trouble overclocking it. It won't run at anything higher than 400 i even tried 412 and it froze. Please can anyone help.

    I think my motherboard is a BH6.

    overclocking is a very complicated area. and even that is an understatement.

    my guess is that you might have 1 card (maybe more) that is very sensitive to PCI frequency changes. some cards are rock solid at higher frequencies, others fail at the smallest deviations.

    try a FSB frequency that doesn't change your PCI bus rate, or (if your mobo supports it) change the PCI/FSB fraction so it remains at 33MHz (i.e. 1/4*133MHz = 1/3*100MHz = 33MHZ)

    hope that helps.
    cheers.

    Well the BH6 only has a 1/3 PCI divider so your stuck at that unfortunetly.

    The next FSB from 100Mhz is the 112Mhz FSB setting.

    What video card do you have? your agp vid card may not like a higtened AGP bus either. Make sure AGP is set on 2/3 divider.

    What PCI cards do you have?

    Have you tried increasing the CPU voltage by 1 volt higher?

    Got good cooling?
