Following up on this, I tested the 256kb version from Techpowerup on your recommendation and I can confirm that it worked. When I used ATIFlash, to back it up afterwards, it backed up at 512kb, so it must be a difference in how GPU-z and ATIFlash handle empty space in backups. Thank you.

Ok... So I have some experimental patches for the driver to bypass the SHA1 hash in the BIOS. You will need to run Windows with signature enforcement disabled.

BACKUP YOUR OLD DRIVER!

16.7.1 - C:\Windows\System32\atikmdag.sys
Code:
Signature: 74 21 3B C6 74 13 83 C0 FE 3B C6 77 16 48 8B

TEST1
Patch: 90 90 3B C6 EB 13 83 C0 FE 3B C6 77 16 48 8B

TEST2
Patch: 90 90 3B C6 90 90 83 C0 FE 3B C6 90 90 48 8B

TEST3
Patch: EB 21 3B C6 74 13 83 C0 FE 3B C6 77 16 48 8B

TEST4
Signature: 0F 85 BE 00 00 00 48 8B 07 48 8B
Patch: 90 90 90 90 90 90 48 8B 07 48 8B

Run each test separately, if TEST1 doesn't work try TEST2 etc...

I don't have a desktop computer atm, so I can't test this myself.

Search for the signature, replace the bytes with the patch bytes. thumb.gif

You will also need to reboot with Driver Enforcement disabled after patching: http://www.howtogeek.com/167723/how-to-disable-driver-signature-verification-on-64-bit-windows-8.1-so-that-you-can-install-unsigned-drivers/
