My RX580 Benchmarking and Results: 30.5Mh/s @ 77.5W (+ 1130MH/s Dcr w/ 125W)

[Apneal]

So my Sapphire Nitro+ RX580 Limited Edition cards came in today, so I ran some benchmarks.

I first tried to find the highest error free memory clock for each memory strap and chose one that performs the best.
I followed this up by downclocking the core until the mining performance was noticeably affected if I'd gone further.
I then proceeded to reduce voltages as much as possible.

The trials and results can be found here:
https://drive.google.com/file/d/0B0CbyDF8Rhg5LS1CdldsUGs5OTQ/view?usp=sharing

I was able to achieve 29.3Mh/s at 77.5W as reported by MSI Afterburner and HWiNFO without any reported memory errors. After 1 hour, the card remained at 42 Celsius in a 72 Fahrenheit ambient room using only 40% fan speed. If power isnt an issue, the 1450 stock clock at 1.125V which can go higher would do great for dual-mining.

I have 6 more of these to play with, and I'm looking to reproduce these results. If anyone has any custom memory straps they'd like me to test just send me a PM (these use Samsung memory).

UPDATE:

After additional strap tweaking, I've gotten to 30.5Mh/s Eth. The card can dual mine 1450 Mh/s Dcr with no power limit, however by balancing power to hashrate, I get 1130 Mh/s Dcr (w/ 30.5 Mh/s Eth) @ 125W

UPDATE2:

The Nitro+ RX580 seems perfectly happy to run on just a single 8-pin power connector. However from my tests, this reduced hashrates by 1% and power consumption by 1% consistently The 1% drop seems to only have been temporary.

Any rom mods. Also what driver version?

[Marvell1]

it seems thse cards  are good for dual mining even the 570 seems to  do 28-29 mhs eth and 700-900 dcr from the benchmarks I have seen with the mem straps updated

thats close to double dual mode on the 480 and 470s , you should try pascal and Lbry coin as well as the dcri

[agente]

with amd what you read on afterburner is not power consume to the wall. there are big differences..

[rednoW]

not good results at all.
my power color red dragon rx480 8mb is doing 30mhs@70w (gpu-z), sapphire ref-like rx470 is doing 28.8@73w (gpu-z) - ethereum only mode

[blue1984]

i get with the RX 470 Sapphire 8gb nitro + -> 28.0 - 28.6 @63w (gpu-z) - ethereum only mode -> 100 - 110 Watt from the Wall

I was able to achieve 29.3Mh/s at an astonishingly low 77.5W as reported by MSI Afterburner and HWiNFO without any reported memory errors.

which bios editor you used??, I used polaris bios editor 1.4.1 but it can't read memory strap entries for my Sapphire RX570 4G Nitro+

my power color red dragon rx480 8mb is doing 30mhs@70w (gpu-z), sapphire ref-like rx470 is doing 28.8@73w (gpu-z) - ethereum only mode

with no mods  and msi afterburner  i can do 29mb  at 68w gpu-z on a few of my msi rx 480 8gb

if I use sapphire trixx I can get -125 mv on a few cards stable.

I mix it with  msi after burner  set clocks at 1150 and 2220



look the new cards are basically the same as the old ones

rx 470 = rx 570
rx 480 = rx 580

So what ever you can find at a good price get.

thanks it works, sapphire rx470-4g has two kind of memory? memory strap shows 1:xxxx and 2:yyyy

That is true - and it will MUCH easier to sell rx 580. So transition to new series is must

they dual mine at double the speed of the 400 series they are not the same cards at all

One is for Samsung memory and one is for Micron memory, only one of those sets of straps affect your timings. I believe the 1:xxxx is the Samsung straps by my tests

What are  the dual mine speeds? (stock and modded). All topics only mention ETH mining..

29mb... if you mean mh.. please provide pics.. I don't think that is possible without a bios mod!

[Apneal]

What are  the dual mine speeds? (stock and modded). All topics only mention ETH mining..

I've been continuing to tweak and also optimizing for dual mining.

So far:

Eth: 30.5 Mh/s
Dcr: 1130 MH/s
VDDC: 0.877
Core: 1300
Mem: 2100
Mem voltage: 0.9
Strap: Custom mix
Mem Errors: 0/min
Power: 125W

NOTE: If you don't undervolt/limit power, it easily dual mines 30.5 MH/s + 1450 MH/s Dcr

very usefull info!.. if i take a 480 to the same numbers 1300 clock - 2100 mem, can i get the same Mh ?

Yes, I can corroborate this as I have MSI RX580's with Samsung memory and had to use the 1:xxxx straps. I also seen a video with cards using Micron memory where the guy had to use to 2:xxxx, so I think the  1: is for Samsung and 2: is for Micron theory is correct.

what software can i use to change the core volt and mem volt?

I don't run my cards on win 7 with claymore any more.

I do smos  give me a minute to set up a miner.
