[Solved] Radeon RX 580 not working

[rna23]

That really depends if your motherboard with its current firmware version has unlocked nvram. 99% of Z170 and above motherboards do not. Which is why EmuVariable.efi is required and uses nvram.plist in the root of your ESP. You can test to see if your motherboard nvram is unlocked by make a copy of EmuVariable.efi in EFI>Clover>drivers64UEFI and nvram.plist to your Desktop and remove them from their current location and then open Terminal and type:

sudo nvram TestVar=HelloWorld

Reboot and then open Terminal again and type:

nvram -p

If you see HelloWorld in the output that means that you have native working nvram and can remove EmuVariable.efi and nvram.plist from your system. If you do not see the text in the output then you will need to continue using those.

By the way, could You run LuxMark Luxball or Geekbench 4 OpenCL to see, how Your card is performing? I really don't understand why my card performs so bad compared to other users. My Geekbench OpenCL result is 49.000, compared to 131.000 of other users with RX 580 ...

Thanks for the advice - just for sure - if I remove these files, will I be able to boot?

yes you will be able to boot.

If you are getting 49k there is something wrong. My RX 480 gets 137470 here https://browser.geekbench.com/v4/compute/1580759

As You made the config, can You guess where could be the problem? Could You suggest some way to find the cause?

If you are using the EFI that I made without changing or adding anything to it at all, you should not be getting 49k. Maybe bad PCIe power connector going to the GPU card itself?

I don't believe that the connector would be bad. The previous cards worked flawlessly and the PSU is only few months old.
I got one idea - how do You power up the GPU? There is one 6-pin and one 8-pin connector ... I read that it may be enough to use the 8-pin. I may try it ...

Always provide the amount of connectors that is on GPUs.

That was it!!!!!! The problem was that I plugged the power in both connectors ... weird ...

Now I got 140.431 in Geekbench

Thanks for pointing in the right direction!

I Was just watching the "Actually Overcloking" video on Nvidia and AMD card power sensors, the power connectors split up the card into three sections for the RX 480, PCi slot powers about half the CUs and the 8 and or 6 pin connectors power the rest and the Chip, lights, fans etc...

The differences in AMD's and Nvidia power monitoring

I was maybe too excited ... the performance still doesn't compare to the performance reported by other users. This wouldn't be critical, but what the problem is that FCPX is freezing very often. Also QuickTime freezes time to time, so there is definitely something wrong still ...

Also I can't understand why the card doesn't work properly with both power connectors plugged in. In that state many apps refuse to use or even recognise the GPU.

Any ideas?
