I want your GTX460 vBIOSes!

[Ket]

Title says it all guys its for my own research purposes, and while I'm at it I'll also upload tweaked versions for people to try out.

nvflash update procedure

This is just a rough and quick explanation for people to reference to ensure they have a successful vBIOS flash.

Assuming you are going to flash from DOS (safest) and use a USB stick here is a step by step procedure to flashing your vBIOS.

- Download a USB boot utility and boot files
- Format your USB stick then run the USB boot utility to make your USB stick bootable, remembering where you downloaded the boot files to as you will need them
- Place nvflash and your modified vBIOS on to the USB stick
- Restart, selecting your USB stick either via BIOS or boot menu as the boot media
- After the USB stick loads the boot files type;

nvflash --protectoff
nvflash --eraseeeprom
nvflash -j -4 -5 -6 filename.rom

Thats it. Ctrl>Alt>Del to restart, run something like GPU-Z to verify the new clock settings and/or voltages and you're done!


Modified vBIOSes

Changes:

Max voltage limit 1.2v
3D GPU voltage 1.1v
2D GPU voltage 0.9v
3D GPU clockspeed 800MHz
Default fanspeed 30%
Memory speed 2000MHz (4GHz effective)
Max fanspeed changed to 100% where applicable

I know what you're doing

Here's one I did for marcolecorse for his Zotac GTX465 to remove the 1.075v limit he had:

Not just that, I want to collect as many GTX460 vBIOSes as I can as theres not many about.

Thanks guys, any and all stock GTX460 vBIOSes are welcome, the more I get, the faster I can build up a GTX460 database for people @ gaul, is your vBIOS 768MB or 1GB?

Here the bios of my Gigabyte GTX 460 1GBOC

Much appreciated

EDIT Does anybody know what the paramater -4 does in nvflash? I keep seeing it in a lot of batch files made by manufacturers but the command itself is undocumented in nvflash.

768 MB mate

Where can I download the Fermi Bios Editor?

[Ket]

You will have to PM orbmu2k asking for it. I appreciate why orbmu2k is careful about handing it out, he doesn't want people ripping off his work. I've found people doing that with some of my work in the past

@ Kaktus, thanks

[Stormad]

Thanks Ket and Kaktus1907 for unlocking the Bios, but I will wait to flash my card untill the fermi bios editor is available to me or untill a new nvidia bios editor comes out that can read the GTX 460 because i'd like to check the bios myself before flashing.
I'd like to mention that my card goes perfectly stable at 820 core in Furmark and Folding@home with the stock Voltage of 0.975 mV. Even with higher voltage(1.081 V) nothing higher is stable and the driver has to restore itself in Furmark and Folding.
So i'd really like to try if more Volts will make it reach 850/900 !

[Ket]

I think I should probably feel quite happy then. My KFA 460 hits 880/4400 so far with 1.1v. Happy days

From a friend I shared the utility with:

Nope, back to lookup table for VGPU voltages, so any invalid selection is automatically ignored. Also I have it on great authority that if you follow NVIDIA reference design (which is the case here in terms of GPU-BIOS access) OVP is at 1.087V

measure on the card and you'll see it doesn't work.
you can set it much like you can with Afterburner but the voltage doesn't actually go up. you could even set it to 1.5V

Hasn't worked for anyone else and when I asked Board Partner they said it can't be done on any reference based card.

[Ket]

I can say without doubt 1.1v works on my KFA, temps are higher than with 1.087v by about 5c. 1.15v also works on my KFA, temps are 7-8c higher compared to 1.087v.

Non reference perhaps?

[Ket]

I'm 99% certain its reference. PCB looks identical to the one Gigabyte, MSI & Co use.
