Hi all. 
My shapphire rx480 with samsung memory got about 27mh/s @80watts with 1000/2250.
My shapphire rx580 with samsung memory got about 27.8mh/s @120watts with 1100/2250.
Seems like rx480 is better not only because the mh/watts but also the price.But 480 are sold out so I have to buy 580 instead.I can live with that.
But yesterday I got a RX580 with hynix. No matter how I change the coreclock/memclock, it only got about 21mh/s @85watts.
My Sapphire 480/580 with samsung always do about 27mh/s on ETH or 330 sols/s on ZEC. but this sapphire rx580 with hynix do 21mh/s on ETH or 280 sols/s on ZEC.
Is that regular? i didnt flash bios,only use msi afterburner. Does it means 580 with hynix sucks?what should I do ?
And which brand is better than sapphire? and why is that?
Thx.

You can't get above 27 with ANY memory without strap mod except in rare cases.
my point is the rx580 only got 21. I highlighted that point just now in case someone else dont get me. Thx.
