Upgraded RX 5500 XT to 6650 XT No Hardware Acceleration, 10mb graphics

[jkbuha]

Hi @MaLd0n - need your expertise here as I am properly stumped by this problem. Have upgraded the RX580 (which was working fine) to an RX6650XT, but for some reason I cannot spoof the device-id to FF730000, whenever I try adding an SSDT or patching in device-properties. Have attached my full ioreg and gfxutil screenshots, maybe you can see something I've missed?

Hi @MaLd0n 

U can use same ssdt but need change things

I tried many times but PCI0.TRP0.PXSX doesn’t work

Also I’ve tried to spoof the device-id using deviceproperties in OC. I can successfully change the Model string but the device-id remains EF730000 not FF730000. 
 

Not sure what I’m doing wrong here…
