    i bsel mod this cpu for 333mhz bus speed but computer dont turn on with mod i think this is for memory limit does i can change memory timing and dram frequency for bsel mod to 333mhz by cpu or pll moding

    Did you try 333Mhz with a 6x multiplier? 333Mhz fsb with the stock normal multiplier is too high for that CPU. You also might need to slightly overvolt the northbridge.

    Hi,

    Another overclocked laptop, the Dell Precision M6400.

    I just put a little wire one the socket to put BSEL2 to VCC. Fsb Goes from 266 to 333 Mhz and the P8700 goes from 2,53Ghz to 3,3Ghz.
    It is a jump of 20% in performance.

    The INTEL Chipset does not see the BSEL MOD and don't lock the processor multiplier to 6x....I'm Lucky.

    Will try next week end with my other M6400 with QX9300. If it works, It could be a 3,3Ghz QX9300 laptop, quite good.

    The QX9300 already has an unlocked multiplier. There is no reason to try to overclock it via the FSB. You can determine the optimal multiplier and voltage using throttlestop. Then you can pin mod the multiplier and voltage to get it to work just how you want it to.

    Yes I know but what a overall performance jump when you boost the FSB!

    Here is the proof with the QX9300 @4Ghz:

    Good work on your overclock.
