    Motherboard replaced, now CPU seems awkwardly slow

    I just had my motherboard changed due to a faulty GPU, this new one seems to be really slow when I run wprime.

    The CPU is a i7 640 UM

    Here are the scores:-

    32M - 100.229 sec
    32M - 117.499 sec


    Is this clearly a motherboard issue? Or I am missing some important settings here, Dell's PreBoot Diagnostics showed nothing wrong (I would guess so since the CPUs are working albeit really slowly)

    Please help, thanks.

    Something is definitely wrong there. Probably time to call Dell again :(

    Run CPU-Z and post the results. Hope they didn't somehow give you the wrong Mobo with a slower CPU attached.

    EDIT: One other thing, do you have the R2 or the R3? I read something about the R2 having a stealth mode (much like the m15x, m17x etc), where it throttles your cpu and gpu to save power. Up until now I thought stealth mode was only for the bigger laptops, but I may have been wrong.

    This is for the m17x, you can *try* it, just to see if it does anything.

    if that doesn't work you can try this one as well:
