RX 570: mem straps msi and sppahire - interchangeable?

[bobben2]

So I have
Sapphire Nitro+ RX570 4G
MSI RX570 Gaming X 4G
They both have Hynix memory, which is good.

The Sapphire card does 29.5MH/s ETH mining, while the MSI card "only" does 28.3 at the same core/mem speed (1100/2075)
Now, I wonder, if I can bios mod the msi card using mem straps from the sapphire card.
I guess I need to confirm that they both use the same memcontroller chip, right?

The memstraps @ 1750 for these two cards (after I doreymilled them):
msi:
999000000000000022559D0031625C489055131339CDD50A004006007D0514206A8900A00200312 010123037AD2C3A17
sapphire:
777000000000000022C29C0010625C46A0551013B50BD509004006007C0514206A8900A00200312 010112E369D293616

Yeah, they are sufficiently different to make me have doubts.
