I have recently purchased a Dell Inspiron XPS Gen 2 (laptop) that has the GeForce Go 6800 Ultra in it. The card sports 12 pipes, 5 Vertex Shaders and Samsung 1.6ns ram...Core (NV42) and memory are clocked at 450/1060. So far we cannot manaully overclock these beasts, since dell has locked us out. Sager, another laptop maker that supplies the 6800go Ultra with their computers can be manually overclocked. So far the only way to change the clocks is to physically edit the bios in Hex (and now NiBiTor) and reflash.

No third party program will manually OC the card (coolbits, Rivatuner) I have tried to flash the sager bios despite the fact that they had different board ID's (NV41 for the Sager/NV42 for the Delll) Of course that ultimately runined the card (it was being sent back anyways)...didn't make sence because I am pretty sure the Ultras had the NV42 cores...but anyways...

And for some reason the 71.89's actually let me manually OC but once a 3D app was detected the screen would flicker and the clocks would drop back to stock 450/1.06, no other driver would do that...

If anyone here has the expeirence in modifing bios please let me know, I can send you my orignal bios.

Here is my 3DMark05 score at 525/1300 http://service.futuremark.com/compare?3dm05=1007655

Stock specs on card:

Core: 450MHz
Memory: 530MHz (1060MHz Effective) Samsung 1.6ns
12 pixel Pipes
5 Vertex Shaders

Check in this forum (http://www.notebookforums.com/forumdisplay.php?f=153) for bios modifications. There's a thread with a download that has bioses at several different speeds that you can flash your Ultra to. I'm currently running the 525/1300 one (as that was the highest available premodified one in the zip), and the laptop is running quite smoothly.

Edit: Found the thread for you. :)

Yeah I know about that thread(s), I was the first to flash my XPS :) . I don't want to keep flashing, I want to manually OC.

I gotta figure if someone had figured out how to unlock the bios, it'd be over there already. ;)

Help me here guys, I was looking through the sager 6800 go ultra bios and found this

On the left is the Sager bios and on the right is the Dell bios. If both are ultra cards and the sager bios clearly state NV42 why does it have a board ID of NV41?

What would happen if I matched the sager bios to look like this

Should I also modify the second like so that e275 sk (sager) reads P324 sk (dell)?

Could changing the board ID's on the sager to match the dell make for a successful flash?

You can try it. Worst case, you fry the card/bios and you have to get another one. :p

I'd be interested to see the results.

I already killed one card!

I've got a second as backup if I decide to try this out, but not sure if I want to do that or not. :p I spent enough time last night playing with the bioses on my 7800's.

Are you sending your extra back? If so, flash the bios that I have modified, if it doesn't work then eh your sending it back. :p

I actually bought it before I had the Gen2 to see if it would fit in my Clevo D900T based laptop. Naturally, it didn't, but I tried anyway. ;)

That's the only reason I have a second one to begin with.

Try it Ronin, be our guinea pig :) Personally I'm happy with just using the modified bios for OC'ing the XPS 2.

Not sure I'm ready to possibly fry a $400 replacment just yet. ;)
