I flashed my Zotac 1050ti OC with the matching firmware from techpowerup. But if I export my VBIOS it's not the same as the original. It changes every time I reflash.

The size is also different. It's 216KB before flashing and ~241KB after exporting.
So I tried using an updated BIOS for the same GPU. But it has the same problem except it goes from 258,560 bytes to 259,072 bytes.

I get this when I run "nvflash --compare"

Code:
NVIDIA Firmware Update Utility (Version 5.370.0)

       Size diffs between file(258560) and adapter firmware (259072)

And this is the output using the default VBIOS for my card and Nvflash 5.692

I am really paranoid right now. Any help would be awesome!

Does the card work like it should?
In order to flash NVidia cards, you need to bypass the certification. I'm assuming it has something to do with that.

Yes it works perfectly. I've played RDR2 the entire day to distract myself

I wish my brain functioned that logically. The fact that the bios checksum changes after flashing triggers my OCD and I would very much like to fix the issue if it was at all possible
