limited edition nitro is expensive as fok tho 
Yeah, its 310eur here in Europe.
And the normal Nitro+ 580 8GB is crap, the memory is really bad with these first batches, slower than the cheap 570 4GB cards.

Wow ! This is a power beast ! Really makes me want to buy some to play with. Any idea about the other dual mining options ? I would be particularly interested in SIA and LBRY.

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

did you set the timings straps to 2000 ? or just OC ? or both of them

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
I am a newbie when it comes to clocking and stuff but I am willing to learn. Are those settings you can set in watttool?

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

This is the news i've been waiting for, thanks a lot for sharing.
Im geting 12 Nitro+ to play with
I hate using 2xPSU on my rigs, and mostly have EVGA G2 1300w, which without adapters cant connect 6x6+8 pin.
Great news indeed
Why arent you using this:
https://www.amazon.com/gp/product/B007JNUSJY/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1
With this:
http://www.parallelminer.com/product/x5-breakout-board-adapter-compatible-with-hp-1200-watt-dps-1200fb/
Add a dinky low wattage power supply to power the the rest

I would go for whatever is the cheapest deal personally. The 570s and 580s are priced about the same as the 470s and 480s, at least in the USA. I think if the price is within 10% I'd get the 500 series just for a little better resale value and possibly slightly higher hashrate (equal at least).
April 23, 2017, 05:33:05 PM
Well, if you're carrying RX 480's or 470's, you'll be feeling good to know that RX 580 are not better than RX 480 for mining. 
I personally don't want any new GPU to come up with huge hash rate upgrade and de-value my current rigs.

So my Sapphire Nitro+ RX580 Limited Edition cards came in today
Did you buy $279 version on Newegg?
Yep thats the one
Never understood why people buy the 480/580 for a $100 premium when you can pick up the 470/570 for 170-180 and it hashes the same.

here are my numbers :
rx 480 4gb
ETH: 30.3 mh
DCR: 1030 mh
clock 1250
mem 2100
107W afterburner
temp 65~
i cannot go furter because the themp will jump and surpass the 75º at 100% fan :S

could you please share your gpu brand + memory type and your bios mod?
April 23, 2017, 03:38:40 PM
@Apneal can you post a link to the Uber-mix v2.3 please, i dont understand, it is a app? i want to custom my timings

That's where the "uber timings" come from.

Thanks for answering my question. That looks way better as the 480's

I got an interesting result testing. 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.
April 22, 2017, 08:38:37 PM
I made a few more changes, namely I reduced the cvddc setting a bit more to 900 mv and decreased the core clocks from 1135 down to 1125 and was able to shave a bit more off my power consumption, which is closer to 102 watt/card now. I also tried Claymore 9.1 using -asm 1 and -dcri 8 and I can get 30.5 Mh/s per card solo mining with the above power draws. If I try dual mining with Decred my wattage shoots up past 120-125 watt/card.

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

I would say - an excellent results!
