You have to use UEFIPatch to fix this. It's described in the readme/wiki how to do it.

Thanks, just tried to apply UEFIPatch, and then I also checked the Pad-file content to make sure it's the same as the stock BIOS. And the Pad-file content does not seem to have issue.
So I wrote the patched BIOS back to the motherboard, enabled Above 4G decoding, disabled secure boot, and then ran ReBarState as Administrator, and it was able to modify the reg successfully this time.
However, after rebooting, the system just hang at boot screen code 99 (For ASUS motherboard, it means USB or legacy boot device error) though I've removed all USB drives already before booting. The screen is all black without even showing BIOS self-test or mobo vendor logo.
Just wondering where else could be wrong.

BTW, I'm able to restore the system by flashing the stock BIOS back using ASUS BIOS flashback without any issue, but re-flashing the patched/modified BIOS will still cause black boot screen.

@terryjx you have to disable CSM
from rebaruefi.
Sorry it's a typo, the one disabled is CSM, not secure boot.

@terryjx do smaller BAR sizes work ? start with 512mb and increase till it stops working
from rebaruefi.
Just tried it again from scratch, and it's working now even with unlimited resizable bar size (key in 32).
Two interesting findings:
- In GPU-z, it's still showing CMS not disabled, although I've disabled CSM in BIOS, is it the same for other people's case or just me?
2, The value of "Resizable BAR enabled in BIOS" is still NO, does it matter?
In HWINFO, I can see the Resizable BAR size is now 64GB, does it mean that it's successful already? The VRAM of RTX A6000 is 48GB, so I assume it's more than enough already.

@terryjx update your GPU-Z and it will display properly. 64GB BAR is correct for 48GB VRAM
from rebaruefi.
Just tried with GPU-Z 2.51.0 which should be the latest version, weirdly the incorrect information is still there.
Probably it's just a problem with GPU-Z, thanks for the help!

Posting my patched BIOS here, just in case anybody else wants to try it by themselves.
I only tried flashing it using ASUS BIOS Flashback function, so suggest you do it this way.
BTW, the .CAP file in the zip package is already renamed to the right format, so just extract it to a FAT16 or FAT32 USB thumb drive's root directory would be good to go.

@terryjx If the GPU is detected and everything I recommend you report this bug to GPU-Z developers since HWiNFO64 has no problem detecting the 64GB BAR.

Can you confirm that this still happens with GPU-Z 2.57.0?
