Do you have a modded bios on your cards ? specially on the one what give you error 43 ?
Did you got that card used or brand new ?
If you did not flashed ( modded ) the bios on your cards, and you bought your RX580/4GB used or from different source, that card might have a modded bios and might was a customer return to that shop where you ordered from.
If this is the case try to use AMD/ATI Pixel Clock Patcher, you can download from HERE
(If you have a modded bios on your another cards, and just added the rx580/4GB to your system and modded the bios, then you need to run the AMD/ATI Pixel Clock Patcher again on your system.)
On those screenshot you posted ... each of your rx 580 cards mining ETH with 10MH/s
?? Did you set your driver to compute mod
