j'ai fait ça sur une 6800 GT galaxy
il suffit de flasher le bios pour un bios de Quadro Dell engineering sample, au redemarrage windows detecte immediatement une quadro 4000
par contre, il faut reactiver apres les 4 pipes de la GT ou de l'ultra avec rivatuner (car la quadro dell est une 12 pipes) mais ça ne pose aucun probleme
l'instalation des drivers maxtreme pour 3dsmax est possible et les performances sont ahurissantes
pour ceux que ça interesse, voici la procédure :

WARNING!!!
DO NOT flash your board if you are not absolutely confident with BIOS flashing. You should know exactly what you are doing and you may damage your hardware if something gets wrong. DO NOT blame me if you did something wrong and dumped your investment. I am not responsible if you follow the instructions here. The steps here may be not 100% complete and true! SO YOU ARE WARNED!
-----------------------------------------------------------------------------------
First you need to download these things:
1. Dell Quadro BIOS from HERE : http://www.newbietech.net/nv510/DELL01.rom
2. the NVFlash 5.10 tool from
HERE : http://www.newbietech.net/nv510/NVflash510.zip
3. OmniExtremeEditorFX for changing the NV40 core/memory frequency from this link HERE
additional tools:
4. Make a standard 3 1/2" bootdisk in Windows
5. Download the 67.02 Forceware driver(just for the start, but any 6x.xx or higher will do) and RivaTuner 2.0 RC15.2, just look for them at download section of http://www.guru3d.com/
5.1: Download SPECviewperf 7.1.1 and/or 8.0.1 and make a test run before you start the modding. Save the results to a text file.
6. Have a spare PCI graphics card handy for the emergency case!
Preparations:
7. Write down these two DOS commands on a paper, you will need them after you boot from the bootdisk:
nvflash -b backup.rom
nvflash -4 -5 -6 dell01.rom
8. For all 6800LE and 6800 (non GT or Ultra) owners you may experience problems with this QuadroFX 4000 mod because you should have undamaged pixel pipelines and vertex pipelines on your GF6800 board. But the PP and VP can be masked out by your card vendor. Here I can only speak for those with 100% fully functional 16x1 PP and 6 VP. Check the other threads on this forum how to use Rivatuner's NVStrap feature to unlock the masked PP and VP. But this premise might be completely false. So, I don't know what happens if some masked PP/VP are damaged. Maybe someone here can correct me.
9. Run OmniExtremeEditorFX you downloaded from above and open the Dell01.rom. Modify the 2D and 3d Performance clock rates of the GPU core & memory stored in Dell01.rom to the standrad level of your standard GF6800(LE,NU,GT,Ultra). Check the specs of your card! 6800 is core 325, memory 350(700MHz DDR). Set both 2D/3D Performance to the same value. Overwrite the Dell01.rom file or make a copy first and then overwrite.
10. Copy your (modified) Dell01.rom file and the nvflash.exe file to your bootdisk.
11. Reboot and go into your mainboard BIOS. Set the Boot sequence to boot from the floppy disk device first. Save the changes and exit the mainboard BIOS.
12. Boot from your bootdisk. In DOS you run this command you wrote down before:
nvflash -b backup.rom
(This will backup your current GF6800 BIOS to the backup.rom file to the bootdisk)
Then run this command:
nvflash -4 -5 -6 dell01.rom
(Type "y" to overwrite inspite of the warning that the PCI device ID is not identical. You will hear a total of two beeps. One at the warning and one when it is finished flashing. DO NOT TURN OFF YOUR PC OR MAKE ANY RESET until you hear the second beep and are back at the DOS prompt!)
13. Now flashing is done. Back at the DOS prompt you can hit reset.
14. you should notice the new boot screen of your succesful GF6800->QuadroFX4000 mod. In Windows install the 67.02 driver. Reboot. Now check the Forceware driver for OpenGL settings & confirm your mod was successful!
15. Still not convinced? (Vsync OFF) Run the Specview 7.1.1/8.0.1 benchmark and compare your results to your first test run. If you want to see the difference really fast, just run the UGS-03/UGS-04 benchmark only. In GF mode this benchmark crawls, in Quadro it flies
16. Run Rivatuner, there install NVStrap and enable all other pixel/vertex pipelines. Reboot. You should have "16x1, 6vp" in the NVStrap tab of Rivatuner. ("12x1, 5vp" is default in the Dell Quadro FX4000 BIOS)
17. Now take a look at the Forceware driver again. You should still have the OpenGL settings beside the Quadro FX4000 logo. Run Specview once more and compare the results.
17.1 If you do not have the OpenGL settings in the Forceware, but see the Quadro FX4000 logo and game optimization settings like those in the standard GeForce drivers instead then do this:
17.2 Run Rivatuner and go to "Main"->Customize->"Low Level system settings"->"NVStrap driver" tab and uncheck "Allow enale hardware masked units" (but you should still see that you have "16x1, 6vp"). Reboot. The OpenGL settings in Forceware must be back now. So, the Quadro driver features must be activated, too. Run Specview once more to confirm.
18. Read the other posts in this thread /forum to finetune your card, like BIOS mod again to enable the masked pipelines without using Rivatuner ot the TV-Out thing. Get nVidia's MAXtreme driver if you are using 3dsmax.
I hope in this step by step instruction I don't miss something important that leads to the destruction of your GF6800 . I am not responsible for your doings.
