I really liked your approach to doing the bios mod and injecting the PowerPlay string via opencore, I went down that road. It worked great right up until I needed to reload and patch the bios with the RedBios editor
Just a note here. You don’t actually patch the graphics card BIOS in my guide. Instead all you are doing is getting the correct settings to pass to MacOS to change the behaviour of the card as injected at boot time using the
PP_PhmSoftPowerPlayTable
string.Of course you can patch the actual graphics card BIOS, however I would not recommend this approach even if you have a dual BIOS setup on your card.
I am moving to a Sapphire 6900XT and will see if I can update this guide with a
PP_PhmSoftPowerPlayTable
string that disables ZeroRPM for that card.
