How to change the default 3D clock_rate ?

I have used the OmniExtremeEditFX to Edit the 3D clock rate to 400/1200 in the bios, but the 3D clock-rate is still 350/1000 and the 2D clock rate has changed to 400/1200. what's the reason why the 3D clock rate is still 350/1000?

p.s it is 6800GT

Thanks

Get the latest NIBITOR (1.8) and edit your default bios again.

I tried it , it was same.
the NIBITOR's creator said there was a bug with the Gainward's
also, all GS have two performance level (one is level 0, one is level 1). normal GT just has one performance level. all GS run @1.4v in 3D an 1.3v in 2D ( no need to edit the bios)
