Also, I'm having issues reading my bios backups on these cards (XFX RX 570 - Elpida) in Polaris. In Polaris 1.4 the memory timings show odd numbers, and in Polaris 1.4.1 they don't show any memory timings at all. Any thoughts?
The bios issue I resolved. Turns out there was a different 1.4.1 fork that I found that showed both sets of timings for the 500 series.
