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

It has the same number of compute units/cores/architecture, so mostly yes, with a 480 you'll probably need much more voltage/power to achieve the same core clock however, and the memory has to be tuned beyond just setting the clock

1. can you run RX 570/580 and bios mod cards using Win 7 instead of win 10? In am tired of win 10 and would like to try 7 if possible.

2. Does anybody know if all those Win 7 pro codes that UK people are selling on ebay are any good and can be activated reliably?
(prices are between $6 and $9)

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

If you use Claymore you can use -cclock, -mclock, -cvddc, and -mvddc parameters when you launch the miner. See the Readme file in the Claymore directory for usage information.

Since Wattool seems to not read values correctly on the newer cards, I been using the miner directly to control the clocks and voltages, GPU-z seems to confirm it is working as intended.

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

This is true, I got similar results as the OP, but my at-the-wall draw per card (6 rig system) was 108 watts after subtracting the PSU efficiency 92% and system idle draw of 50 watts. My GPU-z fluctuates around 80-85 watts, so I think the end results would be similar.

EDIT: To clarify I am getting 30 Mh/s per card (180 rig total) with core clocks set at 1135 and memory clocks set to 2275, core voltage set to 925 mv, memory voltage left at default. I did do the bios mod using the jaschaknack (sp?) PolarisBiosEditor by copying the 1750 memory strap (Samsung memory) from 1:1750 to 1:2000. I did try to copy the lower 1625 strap, but the system was unstable.

For full disclosure, I am also using the Crimson ReLive Edition 17.4.3 drivers on a Windows 10 64 bit system. Bonus, at least with the RX580 I did not have to apply the pixel patch after modding the BIOS.

My raw power usage data is:
Total rig draw: 760W (kill-a-watt reading)
PSU 92% efficient (8% inefficient):  760 - 60.8 = 699.2W (or just 760*0.92).
System idle draw (50 watts): 700 - 50 = 650W
Draw per card: 650 / 6 = ~108W

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

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.

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

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.

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+

I used this fork which seems to work:
https://github.com/jaschaknack/PolarisBiosEditor

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

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 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

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

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

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 an astonishingly low 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).
