Topic: Conclusion Sapphire RX580 with Hynix are not that bad. - page 3. (Read 14073 times)

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.

I just received some Sapphire Nitro+ RX580 8GB GPUs. I am testing with one GPU right now (having Hynix Memory).
I played around with afterburner, but I never got more than 22.5 MH/s (140W power draw according to GPU-Z) (stock settings). Is there something I can do to get better values without modifying the BIOS?

I copied the straps from 2:1750 to 2:2000.. What are the core clock and memory settings to go for 28 ?

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

I have Sapphire Pulse 580 8GB with hynix and i am ok with that cards, They are getting 29.6 MH without problems. Now i have only 2 in work the temp are ok, 62 and 58 degree. I have made some mod on them. Both with the pc are getting 340 W from the wall.  So its not a bad card at all. I am happy with this model. You can check the pic for more details

You expect that gpu to run at 50 degrees when dual mining?

You're stressing it like a madman, it's like you running up a hill while carrying 2 bags of cement.

Yeah definitely don't buy the Sapphire rx580's with Hynix, they're terrible cards with terrible hash rates, since they're the newest in the rx series they also have terrible resale value, the fans are terrible too and can't even keep the cards below 75deg celsius. Don't buy these, get some old (second hand) rx480s for double the price!

Sapphire Rx580 Pulse 8gb Hynix

Proof:

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.

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.

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