    hello I'm Alberto from Italy

    That's the situation:

    WINDOWS 7 Ultimate on Mac Pro (2,1)

    [​IMG]
    (that's the screenshot under Lion just to be a little more complete about system configuration)

    Ati latest drivers 11.12 Installed and working (gaming and everything else are fine)
    Graphic : Powercolor Ati 4870 HD 1Gb

    Need to extract Rom to add EFI for OS X use afterwards

    Tried with GPU-Z 0.5.7 and previous versions but message is always:
    "Could Not Start Driver : Access Denied"

    [​IMG]

    and GPU-Z doesen't open

    Running GPU-Z as administrator and AVG 2011 Pro Fully disabled

    Searched on forum and tried some versions posted by W1zzard , but now no more ideas

    please help :respect::respect::respect:
