No way what? There's about 50 billion guides out there, you couldn't find any of them?
what i find is flashing with Hynix memory not samsung memory , and i am not sure that's the same (i am afraid to damage my gpu).....
the thread i posted above listed a samsung and hynix, RX580 most likely has dual memory, just follow those steps especially the backup BIOS in order to have a fallback once it messed up. its just a simple detailed steps intended for newbies.
do you think that flashing the RX580 nitro+ is same as the RX580 nitro+ Special Edition ?
