[Need Help] Zotac AMP Box + XFX RX560 + MBP 2017 + 10.15.6 black screen  

@naeem_noor, It's likely an issue with the XFX GPU firmware. If possible, flash the vBIOS with one from Sapphire or one with matching VRAM manufacturer.

@itsage, Thank you for your reply.

How can I flash it with the enclosure? I do not have a PC.

I tried it with Bootcamp, but Im stuck with the code 12.

Btw I bought it to use with macOS.

Thanks in advance.

@naeem_noor, You can try it in Windows Boot Camp. I don't think error 12 prevents ATIFlash from working.

Hi @itsage,

I'm getting an error while flashing 'subsystem id mismatch'. I tried to flash this sapphire bios. Here is a screenshot of my GPUZ and SRBPolaris.

Thanks in advance.

@naeem_noor, Keep looking for one that may match the memory brand on your XFX card.

UPDATE: I managed to find a Sapphire RX560 with Hynix memory BIOS and I flashed it! It works perfectly so far, plug and play.
