Nvidia firmware flashing utility for Linux

Hi guys,

EVGA RMAed my dead GTX 770, and I was surprised to see that the new card was running like 15 degrees colder with 15% less fan speed. After looking closer, it appears the difference is due to a BIOS/firmware update. It's changing a lot the noise profile of the room where my riggery is, so I am willing to update my other GTX 770.

Card is a GTX 770 with P/N 02G-P4-2770, original firmware is 80.04.B4.00.72, updated quite firmware is 80.04.C3.00.72.

It appears to be fairly easy with the techpowerup utility for windows, but I have no access to a windows desktop. I know NVIDIA has a Firmware Update Utility for Linux that is packaged in some tegra tools, or packaged by vendors (like IBM which appears to have packaged for Ubuntu this utility for K1/K2 as a .run)

Any of you having access to such a utility for Linux, that could load and install this ROM file : http://www.techpowerup.com/vgabios/144348/evga-gtx770-2048-130628.html ? I am hopping there is some HP sofwtare similar to IBM

Thanks a lot !!!

Hmm, that is interesting - Is it running at a lower voltage? (Sorry I can't help with your actual question)

Some news

1/ EXT64, I honestly have no idea, to my (humble) knowledge the linux driver only allows display and modification of GPU frequency / memory frequency. I don't know how to display voltages, and I read some time ago they cannot be manipulated as they can be in windows

2/ It took me some time, but I successfully flashed the BIOS to version C3. Here is a short description on how to do it for people interested :
- format usb key to MSDOS FAT32
- download your ROM from techpowerup (in my case I renamed to GTX770C3.rom)
- download the techpowerup nvflash flashing utility for DOS : http://www.techpowerup.com/downloads/2257/nvflash-5-136/
- download an image of FreeDOS 1.1 that can be live-USBed. I recommend to download it here (all my other attempts with other images failed, I could boot, but not access the flash utility and the rom) : http://chtaube.eu/computers/freedos/bootable-usb/
- follow the chtaube.eu instructions to copy the image with dd to the usb key
- copy the flashing utility and the ROM to the FDOS directory of the live USB
- reboot and go to motherboard BIOS settings
- make sure Legacy boot is enabled (no UEFI-only boot), then choose the Legacy boot for the USB key (no EFI)
- it will boot FreeDOS, choose option 4 (no driver loaded)
- cd FDOS
- afterwards refer to google on how to use nvflash, in my case :
nvflash --list to identify the index of my card (0)
nvflash --index=0 --save GTX770B4.ROM to backup as GTX770B4.ROM the existing firmware
nvflash --index=0 --compare GTX770C3.ROM to check it's a different firmware but for the good adapter
nvflash --index=0 -6 GTX770C3.ROM to upload the firware to the card

3/ It worked perfectly, firmware is now the same as the RMAed card, as testified by nvidia-settings.

4/ The bad news is, temperature and noise are the same as before

Anyway, I learned a lot, if you think it's useful I can adapt this post as a tutorial.

As a final comment, when I applied the --list command, the utility detected my 2 keplers, but not my maxwell card, I guess a new version of the utility will be required for maxwell flashing.

I wonder if the RMA'd board (or refurb replacement) has better TIM application between heatsink and GPU...

Installed 346 driver that allows CLI request of voltage... both card run at exactly the same voltage

I reached the same conclusion : same part numbers, same BIOS version, same voltage... but 15-20 degrees difference under load
