Conclusion Sapphire RX580 with Hynix are not that bad.

[chiefoforc]

UPDATE2:

finally found out how to deal with Sapphire RX580 8GB with hynix. Its bios are the same as Sapphire with samsung, but how to mod the bios is different.

With samsung, just copy 1:1750 to 1:2000, it is done. easily from 24->31mh/s.
With hynix, you should copy 2:1750 to 2:2000, and tune the clocks, This will make you from 22->28mh/s.

10-15% lower is which I can live with.

Those are just Sapphire , other brand don't have the issue.

The good things with Sapphire is, the temperature is lower even the fans not that fast,and lower watt consumption.




----------------------------------
UPDATE:  

conclusion:

If your GPU is Sapphire 580 with Hynix, it sucks.
I bought 3 Sapphire 580 hynix, they are all 22mh/s top.

But XFX RX580 hynix is 24mh/s which means good.
Sapphire RX580 samsung is 24mh/s which means good too.

JUST dont buy Sapphire RX580 with Hynix !!

---------------------------------
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.

Any solutions? which memory do you guys have? Is hynix worse than samsung?

[PcChip]

in my experience rx470's and rx480's all run about the same hashrate (27.5 / 31.5 respectively) regardless of the memory, once you tune the memory straps, core clock, memory frequency, and voltage

[chiefoforc]

 Here is the Hynix one:

 :DAnd here are the samsung :
http://www.suolatech.com/samsung.jpg

hynix is about 21 and samsung are about 28. Why is that? Anyone knows that?

i've rx 480 mining eth just get 25mh/s

You can't get above 27 with ANY memory without strap mod except in rare cases.

[chiefoforc]

i've rx 480 mining eth just get 25mh/s 

i think 25mh/s is fine with default bios, you can easily get 28mh/s by tune the cc/mc.

But this hynix one , only get 21mh/s with default bios or tuned.

And there are someone PM me that they have the same problem. If you too,reply this topic.

my point is the rx580 only got 21. I highlighted that point just now in case someone else dont get me. Thx.

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

Can you share details about your setup? BIOS version, GPU and memory clocks, voltage?

Thanks!

Is there any difference for miners between the Sapphire Nitro and the Sapphire Nitro+ ?

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.

[batko]

I have rx 580 8Gb Hynix Nitro+ 31mhs, great card for mining.

[PcChip]

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.

try a different motherboard, I have an older motherboard that does the same thing on my rx400 series while flashing/overclocking them (22MH/s), but when moved to my mining motherboards they run fine

Yes that is a great idea. I tried that on mobo 2 of "BIOSTAR TB250-BTC PRO"(6pcie) and "Gigabyte xxx"(my game computer ), they all do 22mh/s, but other GPU on these 3 mobo is 24mh/s means can up to 31mh/s.

Maybe it is not the mobo issue?

Any other advices?Thx.

[chiefoforc]

I have rx 580 8Gb Hynix Nitro+ 31mhs, great card for mining.

that is amazing, May I ask the default bios and tune do 22mh/s or 24mh/s?

If it was 22mh/s , how did you make it to 31mh/s? Thx.

[chiefoforc]

I've gotten mine to 30+ without much difficulty... I don't understand what the hate is about. It needs a little special care, but not anything extraordinary.

It's wierd. I got 31.5mh/s  Sapphire RX480/580 samsung , but only 22mh/s sapphire 580 hynix no matter how.

I am still working on it.

[uray]

nothing wrong with hynix/samsung/elpida/micron their performance is same on average (i am running all of them), each of them just have different optimum setting for strap, clock and voltage

[64dimensions]

I have this card. I'm not a strapmeister. I can achieve 30+ with an explanation.

 BIOS strapping 101: copy the 1750 strap over the higher straps. 28+ mh/s

Luck:

After reading all the relevant 580 threads, treasure can be found in the AMD rebrand thread that can get this card to 30+. But......, the drawback is that this card uses more power.
