6x MSI RX 570 4GB Gaming X (Hynix)
1500 Straps/1150 GPU/2000 MEMORY/1000MHZ
Windows 10
Claymore Eth 9.3 + MSI Afterburner + Modded Bios

28.2 mh/s per card (75w GPU-Z but not a good measure of real power draw)

Crashes @ 2100mhz MEMORY

[Pennywis3]

samsung memory?

Nope, hynix

[Pennywis3]

940 W dual mining is very good dude you should quit while youre ahead

also you can safely lower your core clock to 1100 and still keep same hash that should save a few watts , I have a single 570 MSI 4GB gaming that i do this on

Tried lower cpu clocks, but it afects hashrate quite a bit.
I should probably realy quit while im ahead

Hey Penny, one of my rigs is running the 570 Nitro+'s as well, here's what I learned.

1200 core is the sweet spot on these, looks like you've found it!

Use GPU-Z to check ASIC quality of each card, it is very tightly correlated to how well they'll undervolt. The cards that I have that are ~79% ASIC quality run 836mV at 1200, ~75% runs ~880mV, etc, but I also got a crappy 67% one that wont undervolt at 1200 at all lol, its running 1150 at 930mV

Hi Apneal.

You are right, 1200 core seems to be the best option, more doesn't change hash rate much, but lower clocks do tend to take some away.
Also, thanks for your voltage data, gonna try to lower it even further 

Any idea how to get memory voltage lower? Its working on my 480 series, but i cant do it on 570. Didn't try wattool, coz i dont realy like it.

28.7 vs 29.7 or so using 1130core vs 1200 core is 1mhs really worth 10 or so watts

[Noone.Noface]

Junkey, could you share the strap? That's a high rate and clock for elpida

@Apnel : I have jut got Gigabyte RX 580 4GB Elpida and my setting is Straps 1500 ,2000 . 1170/1990 Core and mem volt 975. Asics 75%, it takes 80W on GPUZ and 29Mh/s.

[WhyMe]

Is there a list of cards and memory model they use ?
I'm using 470 4G MSI Armor OC with Samsung memory doing ~29.4 with 935mV, but there is no stock anymore now.
What 5xx models can do same things ?
Thanks

[M1n0r]

I am finalizing my oc.
And I get 29-30Mhs Eth and 900Mhs Dcr.
But sometimes one share come at 27Mhs or invalid.
I dont get memory error.
Dont understand whats wrong
Here is a screen.

[Apneal]

~1% rejection rate is totally normal and expected with a tight overclock. You can press "s" to see how many shares of ETH each card has rejected internally, and if a particular card is going over 2% you may want to slacken the clocks a hair on it

[npeham]

GPU:

• RX580 Sapphire Nitro+ 8GB with Hynix Memory.

Currently:

• I copied the 1750 strap into the 2000 and 2250 and I got 24-25 mhs and it runs stable so far with not a single rejected share (except Pascal, but these are less than 1%)
  
• I think with a RX580 it should be possible to have a stable hashrate of 29-31 mhs, or not?

Question:

• With which settings (straps, overclocking, voltage) can I achieve this hashrate?
• Does an overheated (>80° C) GPU negatively affect the stability or could the GPU crash? Could it lead to an OpenCL-call-error (Claymore)?
  

Thank you in advance!

[Apneal]

If there's a 2250 field, you MAY have copied the wrong strap. There's 2 sets of straps, one unused and one used. And yes, higher temperature has lower stability.

There are for the Hynix memory (2:xxxx) I think, because the 1:xxxx straps are for samsung memory, or not?
Ok thank you!

[VolDra]

Hi,

I am having TB250, running 6 x RX580 using powered riser with 6 pin, do I still need to plug the 2 molex that on MOBO? Please advice.

Best Regards

[Apneal]

Typically but no one knows if this is guaranteed yet. I have some cards for example that are 1:xxxx Micron and 2:xxxx Hynix. Point is, try copying up the other strap (and use the 1500) and see if that helps, and make sure you actually have Hynix memory because your card typically has Samsung

[dragonmike]

Is there any way to get more volts into the memory? I've got a bunch of Asus bottom-of-the-barrel RX 570 "Expedition OC" cards with Elpida mem. Applied the 1500 straps all the way up and achieved 28.5 Mh at 1300/1980 but unstable after a few min.
I'm not worried about power consumption - is there anything specific I could do to improve this?

[crypsy]

Hello , i have  6x SAPPHIRE PULSE RADEON RX 580 4G GDDR5 DUAL HDMI / DVI-D / DUAL DP OC W/BP (UEFI) and  h81 mb. Still waiting for the power supply   so not running yet . does anyone have  6 of these running stable and at what speed ?Are they with hynix or samsun memory?
thanks in advance

If you want to change your memory voltage, you're gonna need to do some soldering

You mean with "up copying" that I should try copy the 1500 in 1625, 1750, 2000 and 2250? (I building my first rig, sorry for that question)

Yes Im sure that I have a card with Hynix memory (GPUZ says it)

Ha. On 14 cards, no thanks! :-D
So I guess there is no secret from this point. Crank up power and voltage limits, fans @ 100%, find the highest possible core and mem clocks and bob's your uncle...

[64dimensions]

Here is the best I've been able to do on a RX580 Sapphire Nitro+ LE 8GB with Hynix (as indicated by GPU Z) memory.

There are several things you need to do:

1) The card that I have has Samsung as the 1st set of straps and Hynix as the second set. As strap lore has it, take the 1750 and copy it over the 2000 and 2250 straps.

2) For tweaking, I use Trixx.

3) The  most critical parameter is the mem clock. For just hashing ETH, just push it as high as it will go without crashing.

Power saving:

4) I run the core @ 1060 and use Trixx to undervolt at a minimum of -100mV. The card by itself takes about 130W at the wall with these settings.

Hash rate:

5) With a memclock of 2150, I get about 27.2 - 27.5. With a memclock of 2050, about 26.

I've mucked around with the straps with no success.

Nothing here is new, but was gathered up from information scattered throughout the forums.
