Hi, I am trying to flash my msi ARMOR RX 580 OC cards using SRBPolaris and it shows me 2 types of memory on each one, Micron-Elpida and Hynix. Should I change straps for both set of timings? or Should I change only one set of my choice? in order to increase mining speed of the card.

, please advise me
Only change straps for memory thats actually on card...you can change both, but no need,
one is dummy
Thanks Branko, I had to change both set of timings because SRBPolaris did not let me select one of the memory types, so I changed 1500 MHz strap to upper ones and saved the rom files.
