AMD/ATI Pixel Clock Patcher

[SMGJohn]

I have a Rx 480 with a notebook vBIOS in my laptop while AMD does not seem to distinguish between the desktop and the notebook version, I tried using the atikmdag-patcher-1.4.6 to patch my Rx 480 with a modded vBIOS to unlock TDP from 75W to 110W with some other minor changes but the BIOS signature check patch does not seem to work, my operating system is Windows 7 Pro SP1 x64, not sure what I am doing wrong I uninstall the driver with DDU, restart, install the driver then patch with atikmdag and then restart yet I still get Error 43 in the system from signature check failing to verify.
Everything works fine with standard vBIOS's its only the modded ones.

So far I have tried the following drivers, ReLive 17.11.4, Adrenaline 18.2.1, 18.5.1 and 18.7.1, none of them worked the only on that did work was that 2 year old Crimson driver before they added the BIOS checker.
Any advise? I tried flashing the desktop reference vBIOS too without luck still same error, running the tool with administration rights, even tried turning off driver verification in W7 to no avail.
