Sapphire OC rx470 4gb memory difference

Hello, i got the latest generation of sapphire OC Rx 470 4gb GPU's and they have Samsung memory which is the memory that is usually used on the nitro cards. The Samsung memory GPU's are mining (stock) at the same performance as the modded OC Rx 470 4gb Hynix memory version. Could i get an even better performance if i modded the bios of the Samsung memory GPU's ? Is there a Rom for these GPU's, or would a Nitro Rx 470 4gb GPU rom work ? Since they both have Samsung memory ? Thanks and happy mining !
