Hack your Nvidia 5900 to a full 5950 Ultra. The default clocks on the 5900's are 400mhz core and 850mhz memory. The clocks on the 5950 Ultra are 475/950. Many have found that the 5900 using the 5950u bios will overclock even higher than before the flash. Common knowledge is that the 5950u is the same card as the 5900 and uses the same GPU, but has 256mb of faster memory on board.
What to expect after the mod
By flashing the 5900 to the 5950u bios, we are assuming a few things. It appears that the 5950u bios is applying a small amount of extra voltage to the GPU core, allowing it to clock higher. It also adjusts or "loosens" the memory timings, so that the memory can reach higher clock speeds. The card's "ID" is also changed. The driver will now recognize the card as a genuine 5950 Ultra part.
It seems that all of the 5900 cards are pretty much the same. The TV out and VIVO functions may or may not work after the flash depending on your bios choice and card. I never use my TV out, so this was not a concern.
Install Instructions:
1. Extract all in the5950U modpack onto a bootable floppy disk made in WinXP.
2. Restart your computer and boot to floppy
Once the floppy has booted, follow these steps exactly:
3. Backup your original BIOS by typing WFFLASH.EXE-S
4. After the current BIOS is done with backup:
Type WFFLASH.EXE NM 5950.ROM <---exactly as it appears!
5. Hit Enter
Your BIOS should now be updating. Once it successfully finishes:
-type Ctrl-Alt-Delete to restart your computer
You now have a bios modded 5950U video card.
*It is a good idea to re-install your drivers once the flash is done, it is not required, but heavily suggested that you do so.
