Hello everyone,

I have 6x XFX RX580 8GB all with Hynix memory. Out the box they hash at about 22.1-22.7 MH/s. I updated the drivers to latest. I am testing two cards in my gaming pc until the TB-250 gets here. I have tried to under-clock the cclock and it does not affect the hashrate so pretty sure I'm good there. But in trying to overclock the memory, I put it up to 2050, and I drop to 19.5 MH/s. Only on the first card, GPU0, the second card typically doesn't get affected. I am doing this with the AMD settings desktop app. I tried also with MSI Afterburner but same results. Played around with under-volting and got decent power consumption drop.

Finally I patched the drivers, loaded up ATIWinFlash and modded bios(flipped switch on GPU toward rear) by copying the 1:1750 timings to the 1:2000 timings. Saved and loaded and still same hashrate while same situation as far as overclocking while dropping in MH/s rate.

If anyone can help it would be greatly appreciated!!

22MH/s for stock is possible, it should be more like 24Mh/s, but it could be also the motherboard, TB-250 will push it more. Hynix is the main problem, but you should be running at least 28MH/s with good timings. PM me if you want it.

Matthev I am using the BIOS you sent me for RX580 GIGABYTE with 8GB Samsung memory. I am getting around 29.5MH/s now. My core is set to 1300 and memory to 2000 like you said. Can I push anything more out of these cards or nah? If so how?

It depends, I don't really know what I sent you Cheesy

But Samsung it must be Uber-Mix 3.1, you need to find highest memory clock speed with no errors or at lest with a very low errors. It should be running more. I can have 30+MHs with shitty Dual 480 8G and that's with stock config in claymore...

where to find them?

are they different for different brands/memories?

Yeah it depends on memory brand! Read the thread, or PM me I have timings for all memory brands.

I think I'm doing something wrong.

My card is an rx 580 8GB, samsung memories.

I had :
-24.5 MH/s out of the box.
-27.1 @ 2220 @ 0.95

Now I have:
-29.2 @ 2230 @ 0.95 with 1750 into 2000 straps.

I think I should be able to squeeze something more but going higher with ram speeds will crash my system regardless of voltage.

You can't set voltage for memory. 2230 is pretty high, you have good memory. You need performance timings like Uber-mix.

Thx for your answer its strange because I had same probleme with rx480 Nitro + OC 8GB samsung.
Maybe I am doing something wrong ? I just copy the 3.2 straps to 1750 and 2000.
Is there other thing to modify in the bios ?
Ubermix 3.2 where is this straps dont find it in PBE thread ? I have see the 2.3 ligthmix.

Yeah you could edit lot of stuff, but the most important gain in hashrates are performance timings. If your card can't handle Uber-Mix 3.1 than 3.2 should be good, or you need to set lower memory clocks. If you can return the card, do it, the 3.1 is the best you can have, without it that's just little bit better than stock.
3.2 is somewhere in that thread in the end it was few days ago.

How could I now undervolt or increase the hashrate on my RX580 (Samsung Memory)? It is going at ~27.5MH/s. Any pointers where I can read about it?

You can either use Msi afterburner or any other gpu software. If you use Claymore Miner, you can use the -cvdcc option to set the voltage. -cvdcc 900 = 0.9v etc

As soon as I switched to claymore miner in EthOS, my hashrate went to 30MH/s stable. What is the advantage of claymore otherwise, is there a need to set the voltage if I am getting 30MH/s with just claymore or is it possible to get more somehow with GIGABYTE RX580 8GB Samsung? Why are there another place to put the wallet address, does local.config overwrite that?

Thank you so much everyone!

Looks good but what about error and power consumption ?
Ah yes and do you try dual mining ?
I have 4 Nitro LE 8GB Hynix but only 1 can reach 30mhs eth 900Mhs Dcr at 1200/2130 -138mv 124-9 Watt.
3 Other are like 1200/ Ram 2117/2095/2085 at 29+eth 880 dcr 2 are at -144mv.
All with no error.
I use some strap that some one send in this thread.
What strap are you using ?

Now I buy a Asus 580 strixx OC 8GB that come with samsung ram.
I copy the Ubermix last straps to 1750 and 2000 but I must downclock ram at 1980 to get no error and get only 27mhs.
I try the lower version of Ubermix but when I start mine at 2000mhz mem and got only 27mhs push it to 2010 and the error start.
I am dissapointed about the ubermix strap.
Some one have better strap ?

You have bad luck for memory... If you can't run Uber-mix 3.1 you will never have best performance... Use 3.2, but it's a lot lower hs but stable.

Quote from: Candsno8 on May 31, 2017, 01:53:21 AM

I'm looking for a recommendation on which card to purchase:

Sapphire Pulse RX 570 4GB
Asus Strix RX 570 4GB
Asus Dual RX 480 4GB

The prices for these cards are all the same, but I could get the Strix soonest. I will be primarily mining ethash, likely dual mining.

Thanks.

Edit: corrected 470 to 570, as these are my current options.

I have Asus Strix 470, best fans I've ever seen, but no memory heasink so far no problem. Asus Dual 480 is bad, it has Samsung memory, but 8G version is good, but have same performance as Strix 470 with Samsung memory... and O8G was dissaster, I returned that card, it couldn't handle any overclock and also Uber-mix timings wasn't working milions of memory errors. This card have also bad cooling fans are noise and no memory heatsink... it have some errors on memory because of heat!

I found some timings for an MSI card that also used Hynix memory. It's not much faster 25MHs, but it's definitely running cooler (undervolted).

...forgot to mention that's when dual-mining Siacoin so that'll increase consumption quite a bit. Also it's freaking hot atm so fans are going fast. I reckon I can bring that down below 2000W easily if I want to and the conditions are good.

On a sidenote, I've got my two 7-GPU rigs (RX 570's) hashing away and they're only sucking a combined 2200W at the wall. Quite amazing considering my 6x R9-280X rig used to draw almost the same amount of power on its own back in 2014... Tongue

what mother board does 7 GPU now ?

Asus Z270 Prime P can have 8, And Z270-A 9 gpus.

That's horrible. I have 2x RX 470, 1x RX 480 cards and 1x R9 380 (need update but there are no AMD cards...) with 560W at wall. Also I mine XMR with STAK, but when I use Claymore I have 100W more from wall with about same hashes Cheesy

It's all about timings... those basic copies straps aren't fastest.

Any ideas on how timings could be improved for Elpida memory?
I've got 14 of those Asus RX 570 Expedition OC's. They're all featuring Elpida mem... So far I've only copied the 1500 straps upwards and played a little with the clocks. Wonder if there's any more room.

I have good Elpida timings 29MH/s. PM me.

from box ethereum hashrate was 24.5 mh/s than I change timings with Polaris Bios editor. I copy from 0:1500 to 0:1625 > 0:1750 >0:2000. after this I get 29.8 ~ 30 but after 2 minuts go down to 20, 14, 10, 7 till 4.1 Cheesy

Then I returned everything back and copy from 0:1625 to 0:1750 >0:2000 and I get stable 27.8 ~ 28.1 power consumption 130 watt
per card. can any help me with proper timings to get stable 30 mh/s

thi is original BIOS image

Did you check for memory errors? Overheating? Use Uber-mix 3.1 or 3.2. Or PM me.

What's the part number of your cards? How big is bios 256kb or 512kb?
