    Xfx 7800gtx - Oc?

    I just bought a neat XFX 7800gtx and i have some problems..with nvtweak i can try to oc via forceware but in 2D mode i try to set 450mhz for the core and says
    it cannot be set (like to much oc...wtf..)

    I tryed last version of Rivatuner and it does detect 7800gtx but doesnt give me the option to manipulate the clocks..

    I hate that range of clocks and want to set the clocks i like :P

    Greetings guys

    U can find the OC options at the driver settings window ,at the end of the named "ForceWare detected" line.

    I have a question too!
    When I try to set the core frquency over 520Mhz by rivatuner , than appears a massage like this:
    "The driver failed to pass internal test with the clock frequencies you are about to set.
    Please decrease clocks frequncies and try again
    .
    "
    Can anybody tell me , how can I unlock this option?

    do not unlock that option.. u can do so via the expert section of riva tuner.. but doing so gives a performance hit at the same clock.. and u need to force flash a bios to enable the internal test again..

    I am sorry , but my english is not to good . I can not understand it exactly.
    If I want to set the core frequencies over 530MHz than I should flash a new modded bios into the VGA?

    You have hit your limit in overclocking the GPU i think.
    If you flash it with 530 i really think you will get problems booting the card.
    Be prepared to blind flash or use an PCI gfx if you want you want to restore it.
    Everything extra is bad!
