Hello! My first post here...
Im trying to turn one of those chinese RX580 2048SP 8GB cards into a RX570, to make it run in MacOS. Apparently MacOS does not work with the BIOS shipped in the card (no HW acceleration). The card has 8Gb GDDR5 Micron chips and the main chip is the 215-0910052 (which I belive is the vary same as the regular RX570 cards). It has one DVI, one HDMI and one DP port.
I've tried flashing multiple BIOSes from the database (always looking for the ones that support Micron memory), but I only got black screens so far. Im using an CH341A programmer with a clip attached directly to the chip. I was able to read and reflash the original BIOS so I assume the flashing process is OK, and I just need to find a suitable BIOS.
Ive not been able to upload the original BIOS to the database but, for reference, this RX580 2048SP BIOS works on my card: https://www.techpowerup.com/vgabios/252325/252325
If someone has any suggestion about what RX570 BIOS could work it'll be great.
Thanks!
