A 5900XT will not work because it has 2.8ns memory while the 5950u has 2ns memory, trying to flash an XT to an 5950U will result in permement damage. Now aside from the dark facts, what you will gain out of this: Loosened timings for better overclocking, Higher GPU voltage for better overclocking, loosened GPU Throttling so you can overclock at higher temps. Remember!: Not every flash goes right, If your flashing your card and Nvflash says your bios that you downloaded is corrupted, then redownload it, do not use the -i to force flashing with a corrupted bios. In some cases VIVO will not work when flashed with some bioses, try and get a bios that works for you.
Ok, what you must do is flash the bios of your video card. Download dr.dos from here . At this point make a bootable dos diskette so you have a stable operating system that wont crash when you flash. Now, get a tool called NVFlash. Now, Here is a list of commands for NVFlash, but we will use the basics. At the prompt, type nvflash -b original.rom. This command will save your original ROM to file so if recovery needs to occur then you can use it. This Next Step is VERY IMPORTANT. Some ROMS have an imbuilt write protect, type nvflash -r to remove the write protect and nvflash -w to enable the write protect. After disabling the write protect and saving your bios, use the comand nvflash -f xxx.rom to flash to your new bios, Replace xxx.rom with your bios name of course. Now some poeple have made enhanced, or modded bioses for the 5900->5950U conversion and many other nvidia cards, these bioses have enhanced overclock, stability, and performance. To flash these, some require you use the -i command to force flashing since the bios of the modded file is bigger then the original. Also keep in mind nVidia releases many revisions of their card, some revisions are claimed to work better then others so you might want to try different revisions before settling with one.

Will this work on my Asylum BFG Gforce FX 5900 128MB? The FX 5950 Ultra has 256MB mine only has 128MB. I would not think this would work, so I wanted to make sure before I did it. Also could you please post how to make this disk step by step this is the secound flash I have done and its been a while. I don't really remember how I put this disk together its been such a long time. You have been very helpfull and I hope this is going to work out for me. I would hate to mess this card up but I want the gain if it works....
Thanks, Quick071
