Dear All,
I have run into the following issue after installing Catalina on a separate internal SSD of a working Mojave machines. Specs are as follows:
Board: Gigabyte H97M-HD3
16GB Ram
I5-4690
RX580 GPU
Two SSD: Samsung 840 - 750GB (Catalina) and Sandisk Ultra 960GB (High Sierra)
I had a third SSD running a very stable version of Mojave installed also. It all went wrong one day when the Mojave SSD became corrupted. It started with taking ages to boot while the other systems worked fine. When it did finally completely fail the GPU went with it. It is installed in the computer but not recognised, neither by Catalina nor by High Sierre which both recognised the GPU prior to the crash. The GPU does not show any external signs of being broken, LEDs are white (not red as when installed incorrectly) but it does not show up in the system profile nor in the DPCI manager.
I was able to save the old EFI folder for the working Mojave install and used it to do a clean test install. No dice. Mojave, though working stable in all respect will also not recognise the GPU anymore.
I've done my research and played around with different clover settings but to no avail. I currently have Clover 4934 installed. Clover configurator will not let me upgrade to newer versions (server unavailable error).
I am wondering if the GPU is bust or the PCIe slot or if it has something to do with me trying to upgrade Clover (coincidently the Mojave system crash coincided with upgrading Clover).
I have no other system to test the GPU on and no Windows install to test if the GPU is recognised by that OS.
Any ideas?
Thanks, Malte
