Question RX 470's with wrong BIOS, need help finding correct one

[john scoot]

Hello, I recently bought two Asus Strix RX 470's O4G GAMING (I'm 90% sure they are these https://www.techpowerup.com/gpu-specs/asus-rog-strix-rx-470-gaming-oc.b3751) and they seem to have the wrong BIOS. Can anyone link me the correct BIOS for both of these? Here are pictures:

TechPowerUp has several bios downloads available for the hynix memory variant, but I'm not sure on the samsung.

This one in particular seems to be the latest:

It's not a huge performance gain (maybe 10%), but you can also flash an RX 570 bios to a 470 card. The information is a bit dated now but there are plenty of websites that still have the information available if you google it.
