R9 390 Mojave Setup?

Hey guys,

​

I had a GTX 980ti until apple dropped support in Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave, my friend has given me an old R9 390 to use instead as AMD has better luck.

​

I have plugged it in and injected AMD, but acceleration doesn't seem to be on and its reporting as

AMD Radeon R9 290/390 14 MB in the system info, clearly the 14mb isnt correct

​

I am using lilu and whatevergreen in my kexts folder, my mobo is a X99 gigabyte so no integrated graphics

​

Are there any further steps required? As im a but stuck, cheers!
