Updated Information Concerning the 6800NU Video card's. Gigabit and Shuiends have found a script made by Alexey Nicolaychuk aka Unwinder to Perm unlock all the extra pipes and Vertex shaders to = 16/6 like the GT's and Ultra's. First read everything i wrote to learn how to flash youre card, then on the bottom of this post will be the intructions on how to unlock the extra Pipes and Shaders on youre NU. A side note, once this mod is done thier will be no more need for you to use riva tuner anymore cuss the pipes will be unlocked even when you reinstall youre pc.

Since alot of you are still asking how to flash youre video card's and that the current Nvidia flashing sticky is way to old and outdated i will make a small guide on how you can acomplish this.
Make sure youre video card is the Nvidia refrense board. Most companies use the refrense design and they tend to have better results after flashing. The non refrense boards flash but tend to have problems.
Also take note, flashing to the Ultra also changes youre memory timmings to the looser Ultra Timmings, this may have Undesierable results where youre card may overclock higher but also score less in 3dmark. If you really want youre card to be reported as Ultra and Dont care about 3dmark scores not being as high as they should be then go for it. If you simply want a higher overclock, then just mod youre Current bios which is explained below with a higher voltage.
First you need to go to this website , thier you can download all the known bios's for most of the 6800's including the LE's, NU's , GT's, Ultra's, Ultra Extreme, and the new PCI-E cards. The website has bios's for all those card and the ones from each brand name, Pov, PNY, Abit, Evga and so many more.
To find the bios you want just go the downloads section click on Nvidia download section then Nvidia Bios files. Also in the Nvidia Download section thier is a Nvidia Utility section for the bios editor and the program you need to flash youre card with. The editor tool is called Omni extreme edit, the flashing tool is called Nvflash. (EDIT) You can also Use NIBITOR 1.9 or later, i suggest since its newer you try using that instead.
Which ever version you use is up to you, but the versions for the flasher that support the 6800's are the versions 4.42 and above.
Once you download the bios you want you may edit it with the Bios editor , change voltages, the clocks, you can change the clock you want youre card to run @ 24/7 so you dont have the overclock using a windows based program that resets the clocks everytime you change a driver or reinstall youre computer (whatever you set you memory @ make sure its the clock x2 dont set it @ 700 if you want youre memory to run @ 700, you need to set it to 350 cuss 350x2=700). You can change the memory timmings as well for some cards and bios's. Once you edit whatever you want to change in the bios, click on File then save bios (make sure you have a floppy ready) and save the bios to the floppy. You should save it using a short name that you can remember dont make it to long.
After that is done download the Nvflash program i use version 4.42 (if youre just editing youre card's Bios be it a GT bios or NU bios, and you arent flashing to the higher model DL NVflash 5.08), extract the 2 files called Nvflash.exe and cwsdpmi.exe to youre floppy with youre bios. Also to be safe make sure you keep a copy of youre Original bios so if the flash goes bad you can reflash youre card. To get the bios from youre card just reboot the pc with youre floppy that has the nvflash program on it and go into DOS to where you have the A:/ prompt (DO NOT do this in the windows DOS program this needs to be in real DOS mod, in order to get in thier you need to make a Bootable Floppy Disk or CD in windows) then type in Nvflash.exe -b Original.rom this will save the bios thats on youre card.
To flash youre bios thier are all kinds of commands to override things with (to get the commands go into the Info.text file that is in the Nvflash Utility i can only tell you a few commands because each card is diff). If youre using nvflash 4.42 and are flashing say youre GT to Ultra or NU ro GT or LE to GT ect ect you can type in Nvflash -p -u -2 Bios.rom (The word Bios in Bios.rom is actually the name of youre bios you saved to youre floppy so if you named it 6800Ultra then type in nvflash -p -u -2 6800Ultra.rom) If you are only editing a say GT bios for youre GT to have 1.4vcore or more then just type in Nvflash.exe Bios.rom. It will or should say press Y if you wanna update the firmware press Y
I hope this helps. If you have any problems when flashing read the Info.text that came with the Nvflash program it gives you commands to override things like mismatches so you can flash youre card without hassles. If youre wondering how safe this is i cant give you real a good answer to that, it seems pretty safe i made a Poll asking if anyone has had any bad flashes and so far no one has bad flashes (meaning dead cards). Some people have had good flashes but problems with 3dmark or video games. If this arrises, re flash youre card with youre stock Bios that you saved
If you do have a bad flash you can use a PCI card to reflash youre 6800

-----------------------------------------------------------------
[Common]
SrcFile = *.rom
BakFile = %filename%.old
PlugIns = ,BIOSChecksumGenerator
Src0 = 5F 10 C0 00 00 00 00 00 00 00 00 00 00 00 20 C0 00 00 00 00 00 00

7). Now flash that bios to your card and have your 16 pipes and 6 shaders opened
Note:This is for people that know that there cards are 100% moddable. If you cant open a set
of pipes or your shaders do not use this script on your bios. We will be figuring out how to
modify this for you guy's that cant open 16 pipes and 6 shaders.
