I have same MB. (strix z390-e) and GPU (Sapphire Rx580). Can you share your EFI folder's backup? Thanks.Yes, this is what I did to solve it;
Remove EMUVariableUEFI.efi, place SSDT-PMC.efi in Clover/ACPI/Patched add slide=0.
I had the BIOS reset problem before adding the slide=0 to boot args.
I've experienced a few KP's over the last few days. I think I will just go back to emulating nvram, I reboot between Windows and OSX a lot, so sensible restarts are important. 10.15.3 worked like a dream with EMUVariableUEFI. Or keep persevering with OpenCore.@Big-W - thank you for the suggestion. I added slide=0 to my Clover (Legacy) r5109 boot-args, but I still experience the CMOS reset problem
Good find, I've changed my boot.efi for a 10.15.3 backup and so far so goodHerve figured out the BIOS Reset here.

Wow, finally (maybe) a solution! May someone upload a boot.efi backup for 10.15.3? I can't access that forum, because confirmation email does not get to me.
