AMD Rebrand - RX570 / RX580 - Official Thread

[spyshagg]

The rx560...seriously? How many MH can it pull in ETH?

15.5mhs  with 1300/2100 clocks at 60w, basicly half a RX470

tweaked 570 = 27Mh/s @ 91w at the wall (64w on gpu-z).   Could be >29Mh/s >100w but my elpida does not clock enough.

Model and memory?

asus expedition.  Elpida (1850mhz max).

eth only=  1090/1850mhz @ 831mv   = 91w (wall)

Dual mining = 1130/1850mhz @ 831mv =  118w (wall)

[gaato77]

will be possible to see a modded bios for RX570 to get <100 and higher rates of mhs?

[Mattthev]

When you know stable clocks you can set them in bios as default.

It is pretty fucking hard to find the best stable low wattage settings to hard code into the bios when you can't use something like Trixx or Afterburner to try different things 

I didn't mean set static voltages of course   After you test what clocks are stable you can set it in bios with dynamically voltages for clocks and flash it. Not saying it's best option but then you don't need to bother with profiles in Afterburner.

I have Elpida Stritx OC 570. Will try your settings. I have 26.5 Mhz and hihger power consumption. Also it is the hottest GPU in my rig with %100 fans all the time.

I really need to tweak it. Which strap? Any special strap value? @831mV for GPU or MEM undervolt?

Thanks.

You never know what voltages your card can do... Also memory can't be undervolt only memory controller. Performance timings is the key.
My Strix RX 470 has 29Mh/s, could be 30 with better quality Elpida memory.
I pretty love Strix cooling. It's very quiet and I don't have any trouble with temperetures. Asus Dual has very bad cooling.

Like Mattthev said, depends on your chip quality and temperatures.  I've seen people here with less than 800mv on rx580!

Here's the bios I use (the strap I use is selected and  visible).




About the fans being 100% all the time, it was happening to me too on my temporary case.
These "open" GPU's are blowing hot air in every direction. Make sure your cards are not blowing hot air in the direction of the motherboard, because that hot air will bounce back and heat up the neighbor GPU's, which in turn will heat their neighbors even more.

Thank you for the settings. I will post my results as well.

I have one gpu on the mobo and 5 on the risers. My rig case is 7 gpu capable on the shelf.

I will distribute gpus as much as I can to improve air flow.  

As another measure I will put Asus into a position where it breathes the freshest air from the front.

Right now it is it in between other gpus.

But as far as I see MSI has better temps and cooling overall.

Also when one finds a sweetspot for undervolt mV value, is applying this mV value to all GPU speedssets other than the first set (300 Mhz-750 mV) best practice?

[budiselich]

Hi, can I mix RX580 and RX480 on one rig?

[spyshagg]

The difference is so small (750 -> 831) that you gain nothing by making voltage steps.  Also, this is mining, so you will be always in the last state.

[oup59]

You should. I already have 5 RX 570 and 1 RX 470 on the same rig.

[Mattthev]

Hi, can I mix RX580 and RX480 on one rig?

Sure you can, RX 470/480/570/580 no problem, if you are running windows you can also use Nvidia and AMD.
Right now I have R9 380, RX 470 and RX 480.

[gaato77]

any model in particular of this 570 GPU?

some algos switch between less intensive iterations though so I belive the last and second last states should be modified just to be on the safe side.

asus expedition.  Elpida (1850mhz max).

eth only=  1090/1850mhz @ 831mv   = 91w (wall)

Dual mining = 1130/1850mhz @ 831mv =  118w (wall)

I heard the Asus Dual cards have really bad cooling, but what about the Expedition? The cooler seems to be the same.


Currently I have a choice between one of these three cards:

Asus RX570 Expedition 4Gb
Asus RX 480 DUAL OC 4Gb
Msi RX 480 ARMOR OC 4Gb


Which one should I get? The purpose is not only mining but also some gaming on the side. Also, which of them do you think will have a greater resale value in 6mo/1yr, a 480 or a 570?

the cooling is not the best, but its ok if you give them space.   In this image the second gpu is catching heat from the first one.



I havent tested any of the others. But this Expedition has bad memory (1850mhz max). I would go with Rx480

Glad to see someone else notice...

WHY DO THEY HAVE SUCH TERRIBLE COOLING SOLUTION!!

I have to design my rigs in closed boxes with fans in back and front to make a all air beeing pulled out and away from the hardware.
This is really frustratingto me.
Ive seen a few models where they use the good old nvidia solution with 1 single exhaust in the butt...  i love that.

This blow-hot-air-randomly-all-around is really really really annoying.

Its a good cooling solution for 99% of use cases (1 gpu per pc).  I can see its good because with 1 gpu inside the case the temps are low and the noise is very low.   But like you said, for us miners, the  blower coolers are great and all my 290's have one.  Well, they are great unless they are in your living room. They sound like jet engines


I'm doing the same as you are. 7 GPU's separated by cardboard to force air  on one direction.

[amizone]

A few GPU tests Sapphire 5xx. A few successes, but one problem.

I use:

Asus Z270F Strix - Without any problems, 7 GPUs work or MSI Z270-A Pro 6 GPU ready, I have tried, I currently operate about 10 Rigs without problem (RX 4xx)

Hynix on 570 is better then Hynix on 580. Hynix on 570 timing 7777 @ 1750 but 580 hynix 999 @ 1750 but i have to check this because the problem is two different time sets 1: 1750 and 2: 1750 each for another set of memories.


This is my tests, But I have a little problem. The signature for the modified bios driver is ok. But it does not work at the same time 570 with 580 on one motherboard.

If the 4x 570 works and re-sign the driver, the 580 runs but does not run 570.

Simply, it works either it or it. It does not work together.

Does anyone have any advice or idea?

Maybe a new Atipatcher?

according to you I will buy Asus Z270F Strix, is there modded bios to run 7 gpus or I need only the stock ?

I have Z270 Prime P, I'm using the newest one, from the Prime series is needed bios from march or newer I think.

I was able to get my XFX GTS RX 580 8GB to 31 Mh/s!!!!!  

Before modding the bios I couldn't get above 22 Mh/s.  Whenever I would try to change the memory speed it would go down to 18-19 Mh/s.  As someone pointed out earlier in this thread, these cards have both Hynix and Samsung memory in them.  So you have to mod both straps.  I followed the normal guide to edit the first set of timings, 1:1750 copied to 1:2000.  Then for the second set of timings I followed this guy's advice:

.....
Strap copied to 2:1750, 2:2000, 2:2250:
777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17
there is a blank, check you copy all without the blank (forum changes it?)
....

Note, there is an added space in the last set of zeros that you need to delete once you copy it over.

Once I uploaded that bios I got to 28 Mh/s without touching the memory speed or cpu speed.  I was able to get to 31 Mh/s using higher voltage and CPU speed, but I run it a lower speeds to achieve 30 Mh/s and reduce heat.

High Settings:

Low Settings:

I would upload my bios rom but I'm unsure how.  The card has an ASIC of 72% so these setting SHOULD work for a lot of cards.
