Yes, Upon Researching, the MSI RX 560 LP is unavailable anywhere and the Radeon Pro WX 4100 is like £400 (450USD)! Any How, Ill still Keep researching!

First thing to check is your versions of Lilu and WEG to see if they are current.
If they are up to date then try boot argument: agdpmod=pikera

If you bought a used card that had the BIOS flashed for bitcoin mining that's a completely different issue.

Hello,
Thank You for reply.
The card BIOS is "normal", not flashed for mining.
Lilu is 1.4.7 version and WEG is 1.4.2 version.
I tried to ad boot argument with Clover Configurator but the same problem.

EDIT: I want to clarify that I do not have the black screen problem that prevents me from starting. The computer works fine after loading MacOS.

That is Quite weird. What Input Are You Using? DisplayPort, HDMI or DVI

 

[Nicolaiev44]

I use the DisplayPort.
The computer behaves like an original MacPro with a PC graphics card. No boot screen.

What SMBIOS

If you are using MacPro 5,1 or older try the newer 6,1 from 2013 instead. The 2013 MP has dual AMD FirePro graphics cards so that is probably the better fit.

It works but you won't get the CPU PM to work as well as it does with MP 6,1.

I got CPU PM to work so its fine....

MP 6,1 is still the best fit as it's also Ivy Bridge EP based. 15,1 is a Haswell Refresh iMac. The i7-3770 and the i5-3475S are consumer desktop Ivy Bridge CPUs from the same family as the IB EP processors. The only significant differences with IB EP chips in the MP is that they go up to 12 cores instead of 4 and they support ECC memory.

Intel made major changes in how PM works with Haswell. @Sniki could probably comment in greater detail on this topic. No matter what, CPU PM is optional and not mandatory so any SMBIOS that is supported with Big Sur is a possible choice to use. The new Big Sur and OC guide for the HP 8300 will use Mac Pro 6,1.
