AMD Unknown Memory - \_SB.PCI0.SAT0.PRT0._GTF.DSSP

Hey, guys,
I’m new to mining and have been troubleshooting an unknown memory issue with an AMD RX 580 8GB. I’ve triple-checked all the hardware and connectors( USB cable, PCEI/USB adapter, PCIe slot, Riser, PSU cords). I’ve flashed the GPU and it still shows UNKNOWN MEMORY. Any help or direction would be greatly appreciated.

I ran dmsg and the following errors show:

ACPI BIOS Error (bug): Could not resolve symbol [_SB.PCI0.SAT0.PRT0._GTF.DSSP], AE_NOT_FOUND (20190816/psargs-330)

ACPI Error: Aborting method _SB.PCI0.SAT0.PRT0._GTF due to previous error (AE_NOT_FOUND) (20190816/psparse-531)
