Still only 22mh i'm disappointed, I waited a month only mining on 1 card for theses

me too, 570 @ 23.5 around, no chance over to 24 without huge amount of errors.
isnt the gigabyte ones the worst of the rx anyways? wait until sapphire, msi, etc
I have both msi and gigabyte 470s and they all hash the same , i don't think msi and sapphire will differ , and 23 is really bad even if msi and sapphire will perform better their hashrate will be low compared to a bios moded 470
not exactly, MSI Rx 470 4gb 21mh/s, sapphire Nitro+ RX470 22 MH/s, sapphire nitro+ 8gb RX 470 24-24.5 MH/s.
Numbers are
before overclocking and bios updates.
In any case, this is good for used RX 470 (price will be stable) aka sellers market.
