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. There are 2pics @ #4th floor show that hynix only got 21mh/s.

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.

Hynix is good, i have RX580 4gb Hynix, run 31mh/s

thx for your reply, I think there maybe something wrong only with THIS GPU, I will return it to the vendor.

Today, I bought 2 more Sapphire RX580 with Hynix memory, they are both run about 22mh/s, and I tune/mod bios,they are still 22mh/s.

I have bought many Sapphhire RX480/580 with Samsung memory,they are all run about 24mh/s, and +3 if tuned,+3 if bios modded, 31mh/s at last.

I also bought XFX RX580 with Hynix, it is 24mh/s which means can up to 31mh/s and it did.

so I think Sapphire rx580s with Hynix memory are disaster.No matter how you tune/mod it just get 22mh/s TOP.
