the memory clock not going to change just because you changing the mem straps
you still need to overclocking / undervolting your cards
Sorry, this is a newbie question, there will be a problem if I modify the BIOS with a file that I got, the one that shared this, has the same card as I do, only changes version in F7, mine says F5.

Rom files are not interchangeable . You can flash them to another crads , but then your hashrate will drop to lower number's or just going up and down , you might can brick your cards. The cards under full load might going to crash the system , Miners genoil , claymore can crash the video driver ...
That modded bios its not the same what you have on your card ! Dont use it ! It might going to work , might going to give you trouble . Mod your own bios , there is a lot of tutorial for that
