I kind of played with wattool and polaris editor and I reached the next resulting.
6x + 470 Sapphire Nintro 8 gb
ASRock B85 ANNIVERSARY
Intel Pentium G3250T @ 2.8GHz
162-165 Mh / s on Claymore dual 8.1 @ 669 watts on the wall
per card 27+
cca 101-103w per card, Others consume the rest of the system
gpu core 1050 / 820mV
mem samsung 2050 (strap 1625) 900mV
For me, the main energy saving and efficiency.

Nitro+ or nitro?

I always used rx 480 cards for my builds in the past , few days ago received my first rx 470 nitro cards order for my new build.
My first priority was optimizing the bios for ETH mining with low power consumption and high MH/s
GPU-z reporting 75.6 watts , the card real wattage is around 100-110 watts / card .
( Test bench idle power draw at the wall 68-72 watts , with gpu hashing total wattage is 170-175 watts at the wall )
I was able to push the card to the 29.5-29.8 MH/s range , with much more power draw , but never checked the stability on that speed , it was running for 15-20 minutes without any problem .
Played with the bios / timing / voltage , created a modded bios , there is my result :
If im not using the computer to taking screenshot's
the hash rate is stable in the 29.2-29.4 MH/s range

please link your bios
thanks

I just picked up 7 x Sapphire Radeon NITRO+ Rx 480 8GB. I could not pass them up at $200 / each. We'll which memory they have have.
Hi
Please give me best change bios RX 470 4gb sapphire nitro (hynix)
For mining ETH+Dcr
GPU clock and memory clock
And low power really
I have 1 power 1450 oc Green for 6 gpu

rx 470 4gb red devil (27ps)... mod bios... 1080/1950-1080/1975 27,9-28.3 mh/s ETH/ETC and about 275 sol/s on 1140/1900 ZEC/ZCL
You could do better by bumping the core clock somewhat - it's too low.
Tried it. 28.6 MH/s, but power consumption is growing strongly.
Yeah, I have my cards at 1150 (linux) for 31MH/s. It's a good balance, IMO.
Which model / brand do you have?

well watts to hash and even price ratio, I'd say go for 470s honestly.
edit: whatever is on a good sale in any case

So 480 or 470, I am getting tired of just wandering in what to invest.
this memory hynix or elpidia???
As mentioned, its Samsung memoryDid you used the 1625 or 1750 timings ? Any other modifications?
I used the 1625 strap for 30+ but the result wasn't very stable for me. I currently stick to lower clocks at 1125/1950 and 28mh/s. 2025 mem clock for samsung seems a bit low, especially for 30.2mhs.. So I'm guessing he used 1625.. I have been using 1750 but this makes me consider switching to 1625.. thoughts?
2025 seems low??? Wow man you must have really good chips, these are clocked at 1750 at stock so that's an OC of 275. Some cards were stable at this speed, and some werent, so I backed off to lower power stablesettings 1125/1950.

Hey.. great job you did there.
Did you used the 1625 or 1750 timings ? Any other modifications?
Thank you!

What do you consider cheap electricity?

HI
this memory hynix or elpidia???

MY memory hynix
please help me
Hi, i have
RX 470 Nitro+ 8GB (samsung) bios mod strap 1625 timing, -96mv, core 1050, mem 2050 = 74w @ 28,4Mh/s ETH
Its very efficient

The actual power from the wall should be more than 100W. Your value is from the GPUZ.
hm surprising, on th wall 296w = 2x 470 8GB + i5-3450 @ 2core/1,6GHz 0,871v
I looked into hwinfo, there are several values. GPU core power, GPU chip power, GPU power in Vram.
So it could be -
GPU chip power GPU + VRM power in
70 + 49 = 119 * 2 = 238 watts Rx
119w per 1 RX 470 ist real?
-----
298-238 = 60 watts mother board + cpu, perhaps even minus 10% efficiency power supply.
The 119w per 1 RX 470 is about right.
