Unknown "rx 580's" not posting or crashing under load

[peach2]

Hello guys, I recently bought 11 "rx 580's" that seem to be some kind of aliexpress frankenstein cards and I am unsure if they are actually 580's or some other weird gpu. The problem is that half of them wont post and the other half post (no apparent physical damage but they might have some kind of mining bios installed on them but idk how to check to confirm)but with normal rx 580 drivers they crash as soon as i run a benchmark test. The chip die serial number is 215-0910018 and i could not find any other information on the gpu itself so here are some pictures. I was wondering if any of you knew what bios i should flash on them or any drivers to use or anything that i could do to make them work properly
