I dislike the fact that Dell sent them that way, but it's at their discretion, I suppose.

I'm running mine at 525/650 (as on Notebookforums, that is the highest preconfigured modified bios they have), and things are running fairly smoothly. I may take a run myself and start modifying bioses by request. :)

Ronin, DL the latest version of NiBitor (2.3), I submitted the author my bios and you can now change the clocks to your desire :)

I did test it myself, all I did was a 450/1100 and it worked fine.

Changes in this Version

* Corrected GeForce 7800 GTX VID mode
* Enabled GeForce Go 6800/6800 Ultra exact mode
* Added support for GeForce Go 6800 Ultra
* Added option to edit Geometric Delta Clocks on GeForce 7800 GTX
* Added option to save BIOS without changing checksum
* Added option to edit boot up TV-out mode

DL it here

I actually used NiBitor last night to modify my 7800 bioses in an effort to work around another issue I was having. I may do the same with the 6800 Go Ultra bios. I already know what clock speeds it works at..just a matter of seeing where the max is now.
