AMD Radeon Performance Enhanced SSDT

[svandive]

Interesting:
Card Fan finally settled down and both cards are quiet at the moment. I reran the GB5 test, both card's fans spun up as part of the test. Slot 1: 56,069, Slot 2: 61,439

Still running:
SSDT-RX Vega 64 X2-Vers 2.2.aml -- NEW
SSDT-RX Vega 64-Version 2.2.aml

Can someone with a Vega 64 test this SSDT?

Use the same procedure used above but without rename PEGP to EGP0.

I just install your first version, aml and kext.
I got sapphire nitro + vega 64 on last mojave.
It seems to work, I didn't do geekbench test without your mod.
Metal Score : 79340

Look again at the SSDT-RX Vega 64 X2-Vers 2.2.aml, because ioreg shows it is not loaded. Delete the old ones.

Do you have an option to test both gpus at the same time?

Print screen System Info graphics section and PCI.

It's interesting too, sometimes the "System Report, Graphics/Displays" will show the InfinityLink = Yes and other times (like now) the line for the InfinityLink is totally missing.
