Strange Boot Up Problem On Memory Change

  1. Have just changed my system memory over from 512mb PC2100 DDR to 512mb PC2700 DDR
    However when I try to change the DRAM CLOCK settings in the BIOS to 166mhz from 133mhz I get the following error message on boot up and it stalls:-

    Windows could not start
    <windows root>\system32\ntoskrnl.exe
    is corrupt or missing

    This only happens when 166 DRAM Clock is selected or By SPD, on 133mhz it boots ok but only recognises my memory as PC2100
    The system is set to TURBO and the DRAM Timing on manual
    My system consists of:-
    Windows XP PRO
    Epox 8k3a+ Mobo
    AMD XP 2000+ CPU (OC to 1.78)
    512mb PC2700 DDR 333mhx memory
    ATI Radeon 9700 graphics
    Audigy Player Souncard
    Enermax 550w psu

    Help much appreciated on why 166Mhz affects the boot up and what i need to do for my BIOS to recognise PC2700.

    Try flashing your BIOS. There may be some strange incompatibility with your RAM and sysbo.
