GeForce 7800GT Voltage BIOS Softmod

post #1 of 28
Thread Starter 
Not everybody knows how to perform a voltage mod. Today we’re giving 7800GT users a small gift - this universal 7800GT BIOS image contains a small voltage mod of 0.1v in 3D mode, meaning you will be able to overclock your 7800GT even higher. Please note that overclocking will increase your temperatures and potentially void your warranty, so please use it with care. Make sure you keep an eye on the temperatures at load.

Notes:
* Uninstall ForceWare before you flash this BIOS image!!!
* Use it at your own risk! - We're not responsible for any damage that it may cause.
* Overclocking will void your warranty!
* Not for newbies!
* Make sure to backup your current BIOS before you flash this BIOS image!

I cant exactly give you a step by step but these are the files you need to use if you dl the mod files.

nvflash.exe (NV Flash Utility)
cwsdpmi.exe (NV Flash Utility)
bios.rom (Softmod BIOS file)
backup.rom (Normal BIOS file)

The other files are just batch files (scripts). Just make a bootable floppy/CD with DOS and put these files on the floppy/CD. Boot with the floppy/CD and type "flash" and then Enter then wait for it to install and it should automatically reboot when finished.
Please remember to uninstall any current nvidia display drivers you have installed and to reboot into safe mode and run driver cleaner before attempting to flash with this mod. As stated above use at your own risk this isnt intended for people who dont know what they are doing.

If you don't know thats its 'Flash' the BIOS not 'flush' then i dont think you have the knowledge to do this. If this goes wrong your card could become a paper weight.

I'm know sure I know how to make a bootable floppy. I've never done it before. I understand the rest of the procedure... lol I'm probably lacking on the easiest part

is there a guide for making a bootable floppy?

Can you please post few benchmark score on a single card after the soft mod; like 3dmark05 and 06?
I just don’t believe that soft mod works on any 7 series gpu.

I did it and it's made a decent difference. It was wort the 5 minutes it took me to do it

Just make sure you make a blind flash bootable floppy in case it doesn't go right.
