    Right, so from what i can muster up the GPU in my 27" I7 Imac is a Mobility 5850 but under Windows 7 x64 bootcamp it shows as a 5750 and this means that i cant use MSI Afterburner to OC it. I have no idea how to get windows to see my card as a Mobility 5850 not a 5750 and untill i figure out how i cant OC my machine :( I have tried to install the mobility drivers(i think they are the right ones) but it wont accept the drivers it just says that there are already up to date.

    Can anyone here help me ?

    Thanks a bunch.
    Dane.

    Are these the drivers you have tried? Did you install Boot Camp drivers?

    Thanks for the fast response :)

    I installed bootcamp drivers making windows see it as a 5750 and those drivers have made it into a 5800 series :D Thanks! But MSI afterburner is still stuck at 628mhz core clock, i cant overclock it! Am i missing something?

    MSI document looks like this
    [ATIADLHAL]
    UnofficialOverclockingEULA = 1
    UnofficialOverclockingMode = 1
    AccessibilityCheckingPeriod = 1

    [NVAPIHAL]
    ClockDomainIdWorkaround = -1

    What document? What does the app show when you open it? Are you sure you downloaded the right version?
