NVFlash for RTX 50 Series (Blackwell)

[BillyDaKidz]

This is my first time posting here, and after spending some time tinkering with the software, I’m confident this version of NVFlash can flash any compatible BIOS (as long as it’s for the same GPU chip) to your card. I personally tested it by flashing my ASUS RTX 5070 PRIME with the ASUS TUF BIOS, and it worked flawlessly.


All of this was made possible thanks to his previous work by Kefi — huge shoutout to him! (https://www.techpowerup.com/forums/...afe-board-id-bypass-up-to-4xxx-series.312608/)

Here is with the ASUS TUF 5070 BIOS:

Here is with the MSI VANGUARD SOC BIOS:

Also, If you wanna try it yourself, I put everything together on my GitHub, check it out here: https://github.com/WillyBilly06/NVFLASH

Going to try and flash the OC bios for the Gigabyte 5070 Ti onto my non-OC one, although I assume more can be done there.

Successfully flashed the Gigabyte Gaming OC bios over my MSRP Windforce
5070 Ti, everything seems stable. (Well, as stable as a 50 series card can be)

That being said, it seemingly dropped the average clocks in steel nomad a bit but got the same score as stock.

I have tried to flash a 5070 Ti to my card but no luck. Seems like any ROM that doesn't match the "chip level" will cause this error, but you can flash the BIOS from different vendors as long as it's the same 5070 Ti of yours (Flash Gigabyte to MSI or Gigabyte to ASUS, etc). And any modding to the ROM file will cause the Legacy Bios to be mismatch that will eventually cause the uProc to pop up with the code 0x9F.

I'm trying to flash the 5080 Zotac Solid to my 5070Ti Solic OC. Same die, just disabled cores on the 5070Ti die. I'm seeing bios mismatch error using nvflash's latest version. Do you know of a way to get around this with the blackwell cards?

Sadly, doesn't work for the MSI INSPIRE 5080 SFF. Tried 3 different Gigabyte BIOS (including the SFF one) and it ends up with the card being disabled in device manager as a "Problem with device".

Okay so I tried the GIGABYTE bios on my 5070 ASUS and it's really weird. I installed the driver and the card still won't recognize but the GCC recognizes it. It's probably the issue with the GIGABYTE bios where they probably locked the bios to certain cards of their brand only. But if you try it with ASUS bios, it would work fine!

Appreciate the response. Sadly, its the Gigabyte specifically I wanted, as it has the extra 50w max power, over all other AIBs. Every single BIOS for the 5080 on here has either 360w or 400w max, but the Gigabyte has 450.

I tried another MSI one.. the Gaming Trio X, seeing as I at least have an MSI. But nope, same issue.. no dice.

I might try an ASUS ‍

Hello Billy,I tried to flash a higher-frequency ASUS vBIOS onto my MSI laptop (RTX 5070 Ti), but found that the device IDs for Razer and ASUS RTX 5070 Ti Laptop GPUs differ from those of MSI and other vendors, being 2F58 and 2F18, respectively. PCI Device ID: GPU is 2F18, vBIOS is 2F58. It seems this version (of the tool) still cannot bypass the Device ID matching check, showing the error "Mismatch Type: 0x00000001".

Hey! So I tried it on my ASUS laptop but with the RTX 4070 and using both my NVFLASH and Kefi's one but it truly cannot flashes other bioses from different vendor so I would guess that they locked the file to prevent cross flashing on the laptop. Also I wouldn't recommend flashing the bios on the laptop since it only has 1 bios chip and if the ROM corrupted, you might need to reflash it with the CH341a, which could void your warranty. But everything on the PC's cards would work fine as normal.

I've tried 3 different MSI 5080 Inspire cards and it definitely isn't working for that model. Even using

Nvflashb --display

Doesn't show the card vbios info. I even tried the official nvflash64 and it doesn't output info either.

Not sure what MSI have done.

I just flashed an MSI RTX 5060 Ti 16 GB Gaming OC BIOS (220W power limit) onto an MSI RTX 5060 Ti 16 GB Ventus 2X OC Plus (180W power limit). I haven't tested it yet, but the flashing process went smoothly using NVFlash 5.867.

Seems to be something to do with the 5080 INSPIRE specifically. As I say, even the non modified nvflash can't read the eeprom.

Hi guys!

I was looking a solution to different vendor vbios flash to my 5060TI. There is the solution if someone interested:

The -6 flag (argument) is required even for SAME_VENDOR → SAME_VENDOR BIOS flashing due to a board ID mismatch. I also had to use it when flashing MSI to MSI. It is not required only when flashing your original BIOS.
