BIOS reading not supporrted on this device (ASUS ROG STRIX RTX3090 OEM)

[ThomasQ]

I just received a VBios updater for my GPU (P-Mode:94.02.42.00.AB ,Q-Mode:94.02.42.00.AA) that enables ResizableBAR on my GPU that came in a pre-built Asus Rog Strix GA35DX.
After updating my VBios and GPU-Z, I am no longer capable of reading the Bios with GPU-Z 2.51.0, but it still seems to work with the nvfash app that came in the updater.
Any ideas?
If someone is looking for a current Bios for the above GPU model, let me know.

Can you send me that updater+nvflash+everything else they gave you to w1zzard@techpowerup.com?

 

[ThomasQ]

done!

Update: Dumping the vbios works with GPU-Z 2.50.0, but not with GPU-Z 2.51.0

Still broken in GPU-Z 2.52.0

Can my SIV utility dump it OK, see https://www.techpowerup.com/forums/...supported-on-this-device.290957/#post-4744022

I can confirm this bug, I have this card:
Palit RTX 3070 GamingPro OC

I can´t read the VBIOS with GPU-Z 2.51/2.52/2.53/2.54 but it works with 2.50 or earlier version.

Same here: failed uploading this Asus 3070 Turbo non-LHR VBIOS with GPU-Z 2.54 until tried earlier GPU-Z version

The latest windows nvflash 814 save VBIOS without problems

Ran in this issue again with Asus 3060Ti VBIOS. And eventually found a clue: there are some bugs in nvflash 5.792 and it is the version bundled with GPU-Z 2.56.

Saving of this GPU VBIOS works fine with nvflash 5.735 and with nvflash 5.804, 5.814, but versions 5.763-5.792 just fail with

ERROR: A system restart might be required before running the utility

So I hope it may be fixed by just updating the bundled nvflash

FYI, modern NVIDIA BIOSes do not start with 55 AA, but "NVGI"

That's great feedback, much appreciated, thank you!

This problem was resolved with "GPU-Z v2.57.0".
I can now read the Bios of my RTX 3090 GPU again, just like I could in "GPU-Z v2.50.0".
Thanks for the Update!
