    CPU Speed Problems


    Hi everyone, this is my first post and hope I provide enough information for some help.

    I have upgraded the CPU to a Northwood P4 2.8Ghz, 533Mhz FSB as I was told by HP that this was fine and on FIC webiste it says it accepts 2.8Ghz, 533Mhz FSB. However it is only running at 2.1Ghz, 400Mhz FSB (as per BIOS and Intel CPU Identification Utility). Any help, advice, solutions would be greatly appreciated.

    I have a FIC VG31 Motherboard which is part of a HP Pavilion 423.uk PC, Windows XP Service Pack 2 Installed.
    Memory Module(s)
    Memory Module 1 : Siemens HYS64D32000GU-7 0211F8D5 256MB 8x(32Mx8) DDR-SDRAM PC2100U-233-750 (CL2.5 up to 143MHz) (CL2 up to 133MHz)
    Memory Module 2 : Micron 16VDDT6464AG-265C4 C502A69B 512MB 16x(32Mx8) DDR-SDRAM PC2100U-2533-7510 (CL2.5 up to 133MHz) (CL2 up to 100MHz).

    Some motherboards have a jumper on the board for 400bus or 533bus im not sure if your is one of those or not. Look in the bios to see what it says abour CPU settings in there.

    first update your bios, the main problem when upgrading your cpu.
    2 clear your cmos
    3 check your jumpers.
