Xfx 7800gtx - Oc?

[neosho]

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

get the new rivatuner, and make sure you set the 3D Clock

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.
