Well, Samsung, Elpida, Hynix, all of them is fine.

But I bought a RX470 that is making me to lose the hair (lol). Apparently it comes with a Micron low clock ICs. It doesn't run at 2000+ even with loose timings. With reasonable timings, I can run without issues between 1900 and 1930, but I can only reach 910H/s CN-V7 and 1000H/s CN-Heavy/Haven (at 1150/1920). Isn't a powerful result, right?

Wich timings I have to reduce/increase to improve performance in CN variants (maybe Ethash, but isn't the focus), considering the clock is a hard limitation? I have a little list, but I think is far from a complete list:
ACTRD/ACTWR, RASMACTRD/WR, TRCRD/A

But I'm not getting conclusive results. Is a painful pleasure to optimise it.

Is there another timing that I'm forgotting to change?

It would be nice to know exactly which micron is that, I have 1750MHz variant on my RX560s, and
no trouble to go over 2100, and even 2300 with loose timings

Yes, my RX460 4GB has Micron and go around 2100 (but has BGA issues). I will disassemble the RX470 to see the memory ICs to confirm (or not) my suspicions and take pictures to post here.
