So I noticed on 3 different cards that I tried to add the voltage offset to, that the FF 00 01 07 0C does not show up after doing (in HxD) Edit > Select Block and putting in the beginning offset from the bios.text (atombiosreader file) and the length. Am I correct in the statement that these cards will not take a voltage offset at all or am I missing some more knowledge to force this in?
You need to check what the voltage controller is, and then add in a corresponding voltage offset then change the table offsets and whatnot to make sure the bios is still valid
So adding in the voltage offset I got, following the above video in the thread I have been able to successfully add it to a rx 480 Nitro+ 4gb Elpida and also to a MSI rx 570 4gb Hynix. Following the same exact process on my RX 480 Sapphire Nitro (non +), MSI rx 570 Gaming X 4gb Hynix and MSI rx 580 8gb I could not add it.
For example the MSI rx 580 8gb the VoltageOffsetInfo starts at abea with a length of 0034 but after adding the values I do not have FF 00 01 07 0C in the changed values like I did on the other 2 cards.
