GPU-Z: PNY RTX 5080 BIOS reading not supported

[tech__ace]

Hey guys,

I’m trying to use GPU-Z in Windows 11 on my PNY RTX 5080 to dump the ROM. I have the latest version of GPU-Z which has full support for Blackwell GPUs, but I’m getting a “BIOS reading not supported on this device” error.

Is there something I’m doing wrong? Or will there be an update to allow BIOS dumping for 50-series GPUs?

Bios reading is not supported on Blackwell until I find an NVFlash version that supports it

Makes sense. Thanks for answering!

Sorry I'm using a translation software to communicate with you.

Have you considered adding the ability to display the UEFI GOP version in GPU-Z?

I wrote a GOP Update Tool, and in some user feedback, some users want to see this information directly from GPU-Z. Maybe you can implement this more conveniently in future versions.

That's a great idea. Do you have any details where to find the version in the BIOS binary? probably near 0e f1?

I'm glad you're interested in my suggestion.

The amount of code you need to add this functionality depends on how much information you want GPU-Z to display about UEFI GOP (e.g. UEFI GOP version number, size, signature, backup, build time, signature date, modification, etc.) and the correctness, and there are many special cases, such as multiple different versions of UEFI GOP in a single VBIOS, and the same version being signed multiple times.

In addition, the GOP tool I wrote also adds a series of specifications and modifications based on the original NVIDIA firmware, so I thought you might want to discuss these technical details with me in detail.

In addition, these information detection methods applied to GPU-Z may also need to be applied simultaneously to techpowerup.com/vgabios

You can see the tool I released from here and try it out first.
Currently, the GOP tool provides two version branches for Turing and newer architectures:
