Conclusion Sapphire RX580 with Hynix are not that bad.

[tf2addict]

I can't get my Sapphire PULSE 4GB Hynix above 23.x ETH-only or 22.x/0.68 dual ETH/SC.  I've done the BIOS mod.  Strange thing is changing the memory clock in Wattman seemingly does nothing.

Also has anyone figured out how to get rid of Wattman completely so that Afterburner will function normally?  I did a modify of the installation but Wattman returned.  Guess the next thing is to uninstall everything and do a driver-only install.

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.

These cards can actually hash at 30-31 very easily. You need to mod the bios a bit but nothing out of the ordinary for AMD RX series cards. I have an 8x GPU rig of RX 580 Nitro+ 8GB. Total rig draws just under 1500 Watts and I"m pulling about 244 Mh/s ETH + about 4850 Mh/s SC. It is sort of a lot to type out. I'm going to make a video on it here in the next few days as many people have had issues with these cards including myself. I was new to AMD when I bought these so it was a bit of a learning curve. Now that I am familiar with it I don't mind them. Let me know if you would like to know more and I'll post the video link here.

I have now 4x Sapphire Radeon Nitro+ RX580 8GB (11265-01-20G, A1727), all with Hynix. BIOS modded, mining with Claymore 9.8 and AMD Beta drivers with stable 30.3MH/s. See screen shot below.

Hey, have you tried dual mining ? Also, did you get any incorrect shares ? if yes how many in 24 hours ? Thanks.

I'm not dual mining. No incorrect shares.

That's awesome, I was kinda hesitant to move to beta driver but thanks I'll uninstall old and  update today.

I had a hell of a time getting my Sapphire PULSE 570 to OC.  Finally got there with a ROM from Anorak's site.  I get 27 MH/s or so on only 70ish Watts.  I'll take it.  The Sapphire is actually running about 1 MH/s faster than my XFX on slightly less power.  I have never been able to get either 570 above 28.x MH/s even at full power.  Probably just unlucky with the silicon lottery I guess because I think I've tried everything.

I have six Sapphire 580 Nitro+ 4GB (Hynix) cards. 4 of them running at 24.*mhs and 2 at 22.*mhs I've looked everywhere for bios mods and everyone says different things. I'm afraid to try any of them because I don't want to brick my card. I'm fairly new at these modding/clocking stuff so I need some guidance.

Is there someone with the same card that can share settings that are tested and working? I'm not looking for free info - I'll happily mine for a day or two(not much but from the heart ) to your address if someone can give me a working solution.

PM me and email me your stock bios

Make sure you are using the new AMD driver with the epoch fix, it really works.

[Ortek]

Make sure you are using the new AMD driver with the epoch fix, it really works.

It doesnt work for everybody, some people have problems with hashrates jumping up and down when using the AMD blockchain driver. But hey it's worth the try isn't it
I have Sapphire 580 Nitro+ 8Gb cards with Hynix and im hashing with each at 30.5MH stable, the fan doesnt even run all the time.

The thing is it takes some time to get to know your GPU, each card is or can be different. For the peeps that want to flash quickly and get mining it could be a nightmare yes...true that. Just dont give up is my advice.

which settings and which bios mod you use, come with my 580 8gb nitro only on 26mh / s with 96watts consumption

Hello everyone,

I'm fairly new into mining and I just want to share with you my experience with a Radeon RX 580 GPU paired with Hynix memory.

My card is a Sapphire RX 580 8GB Nitro+ Special Edition (blue card; dual bios, factory OC: GPU @ 1430MHz / Mem @ 2100MHz) with 1x 8-pin and 1x 6-pin power ports.

I'm currently mining ETH and Decred on Windows 10, AMD blockchain driver and using Claymore 10.0 dual miner.

Going with the stock bios this card got me around 15-16 Mh/s, while the OC version went up to 18 Mh/s.....a little disappointed as everybody else (from what I've read online) gets 24-25 Mh/s stock (correct me if I'm wrong here ). I overclocked the memories a little bit more and gained a max 20 MH/s, but temps went even higher ~74 degrees Celsius, fans louder and eventually memory errors started to show up in HWInfo.

Then I started do modify the stock non-OC bios with SRBPolaris V3 and changed the 1750, 2000 and 2250 straps from the Hynix section with this (found on anorak.tech):
    
    777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17

Now, running claymore with the GPU @ 1150Mhz / 950mV and mem @ 2250MHz / 950mV (values sent as parameters to claymore), the card gets me ~30.8 MH/s (ETH) + ~919.300 Mh/s (Decred), while drawing ~120 Watts (reported by GPU-Z). My system has been mining for 2 days straight with no GPU memory errors reported and temperatures are staying at ~55 degrees Celsius, fans 49%.

With all these mods done to the card I am quite satisfied with it and I'm planning on getting more

Sorry for the long post and I do hope that the above info will be of some help to people who have RX 580 GPUs with Hynix memory.

Cheers!

That's the same Hynix performance strap used in PBE v1.6. The Sapphire RX 580 8 GB (blue faceplate) also has Samsung timings in the first set of straps. The PBE v1.6 'one click timing patch' option changes both sets of straps to the bundled performance timings (UberMix v3.1 for Samsung). You may also get a bump in the DCR hash by adjusting the -dcri from the default value of 26 to ~30 without affecting the ETH hash rate.

[bouldou]

Anyone has tried to optimize some RX580 with 4Go of RAM only ?

I have a MSI one and managed to get 28 Mh/s but nothing more... Quite a pity

[Vann]

I would try the PolarisBiosEditor v1.6 'one-click timing patch' bundled performance strap. I have a Sapphire Pulse RX 580 4GB. With the PBE bundled strap, 1150 MHz core clock, 2050 MHz memory clock, -96 mV underclcok and -15% power limit in Afterburner -dcri 30 I get 29.8 MH/s ETH and 895 MH/s DCR dual mining with 125-145W shown in GPU-Z.

Nice !! Thanks a lot, I'll try that right away

Edit : what is the brand of your card's memory ? Hynix or Samsung ?

[Vann]

Most Sapphire RX 570/580 cards have two sets of memory timings, each from a different brand. My Sapphire Pulse RX 580 4GB has Elpidia in the 1: set of timings and Hynix for the 2: timings. PBE v1.6 'one click timing patch' will apply the performance strap for each set of straps based on which memory type it detects.

16 MH/s stock is insanely low.  I have two Sapphire 580 4GB (Hynix) and got 24 out of the box.  With Anorak's power save BIOS I get 27.x.  Not great but I haven't been able to get any more than that.  Anorak's memshift BIOSes were no better.  I'll try your posted clock value later, would love to get 30 even if it's a bit power hungry.

[DigitalVHS]

Stop talk a shit about  30,5-31 mh/s with rx 580!!!  Yes, its possible to get 31 mh/s but how long?? Rig will shut down after 1 hour, 3 hour..in the best case rig will shut down after 24 h.
