CPU: E5 2680V2
Graphic card: sapphire r9 280x (vega 64 or r9 580)
MacOS : Mojave
I met problem, If i used AMD graphic card, all of monitors would be black screen after entering desktop. If replaced NVIDIA graphic card all of monitors work fine. For the BIOS boot...
As same as cracking dvmt setting to unlock msr locked that could help you to solve the situation.
The risk is that you maybe destroy the motherboard BIOS. If it happened you need a BIOS programing to flash BIOS.
When my platform was updated to 10.14. I found RX580 H.264 and H.265 decoding work fine, but H.264 and H265 encoding didn't work.
Today I updated my desktop tp 10.14.1. Even H.264 and H.265 decoding support is moved from 10.14.1.
I don't know why.
Thanks for your tutorial. I have a two LGA 3647 CPU platform and I could not genrate SSDT for it. So these two CPU could not have CPU turbo.
Could you please make tutorial for these CPU which SSDTpregen recognize them as unkown tpye？
Machine model is DEll 7920. Sorry for my poor English！
