    Default GA-EP45C-DS3 Can not get 4CB DDR3 to run at 1333 MHZ

    Hi

    Have recently built this pc with a E5200 cpu and 4gb of DDR3 . The memory is 1333 mhz but i can not get it to that speed. it is currently running at 800mhz...Any ideas what I am doing wrong.

    Full spec is

    E5200 @ 2.50 STOCK
    Patriot 4gb ddr3 1333
    160 WD blue hd.

    I am running F5 bios. Tried the f6a beta but no difference

    thx

    Memory runs at FSB(CPU Host frequency) x SMM(System Memory Multiplier).
    The highest SMM for P45 is 4 so 800(200x4) is the most you can expect without OCing.
    Not all E5200 can handle 333MHz FSB that is required for DDR-1333(333x4).
    Please post memory part# and screen capture of MemSet main and SPD window.

    Ahh...so it is the cpu thats the prob. Currently running 266 fsb x12 multi for a 1066 memory speed...running a stress test now...will see how it goes and tweak it up if I can

    thx

    Set VTT(CPU Termination) and CPU PLL to default values also.
    Temps reading with ET6 or are those core temps?
