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=sharingI 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. http://imgur.com/DnB9WH1I 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.

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

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.

rx 470 = rx 570 rx 480 = rx 580
So what ever you can find at a good price get.
That is true - and it will MUCH easier to sell rx 580. So transition to new series is must

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

I don't think that is possible without a bios mod!

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

I believe the 1:xxxx is the Samsung straps by my tests 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.
