Topic: Conclusion Sapphire RX580 with Hynix are not that bad. - page 2. (Read 14073 times)

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

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.

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!

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

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.

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

PM me and email me your stock bios

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.

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.

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

I'm not dual mining. No incorrect shares.

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

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.

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 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.

Is there any clear indication or way to tell which brands/specific cards are using hynix or Samsung? Or is it just down to luck of what you get?

Thanks, I came back to answer my own question, after some digging turns out the PCIe risers i'm using are shit, after switching the PCIe bios settings to GEN2.0 (they were GEN 3.0) the problems are gone and all cards are hashing normally.. Although, I've set the clock to 2150 to make sure I avoid any other issues later on.

Download HWinfo, run sensors only and see if there are any memory errors. I've never seen a Bios modded RX 580 that can you can overclock the memory to 2250 MHz and not produce tons of memory errors.

Hey thanks man, so I managed to bios flash my rx 580s all six of them, I was very happy when they started hashing at 27MH after bios mod and 2000mhz memory clock, then even happier when i overclocked with MSI afterburner to get 30.1mh on 2250mhz memory and 1150mhz core clock.
Then the strangest thing happened, I have all cards on same settings yet only one gpu is always displaying this error on claymore v9.6
I tried replacing the gpu pcie slot, putting it on default clock speed (1411mhz/2000mhz) and even reflashing it but still same issue...
I'm using combined amd driver from cryptomined channel on win10.

any ideas what's going on ?
thanks ^^

This one (Version 2) is working fine for me:
