1600w psu a little overkill imo Smiley

28mhs / card
95w / card

Very nice, if true.

Yeah, maybe he can get most out of it by adding additional gpus and dual mine.

Instead of just bragging about configurations and results, what about sharing some knowledge about how you reached those levels?

How in the world are you attaining that?

I'm assuming he:

underclocked CPU
undervolted CPU
undervolted system RAM
undervolted GPU cores
undervolted GPU RAM
underclocked GPU core
using custom memory straps
overclocked GPU RAM


That about right deadsix ?

Pretty much Smiley

Impressive efficiency for an AMD setup!, very good!
the expensive PSU helps but the real deal is the NITRO+ with the modded bios and very precise tweaking.
good job!

I can get significantly more efficiency than that but with NVIDIA gpus (that costs 50% more money) so yeah... your setup rocks Smiley because at the price of your rig, it is almost impossible to have better efficiency than that.

A friend of mine says that i have Power Efficiency TOC hehe, yeah, i am freaking obsessed with mining efficiency, that's why i use NVIDIA cards instead of AMD, and i don give a damn if they cost 50% more because i pay so little on power (and power here is EXPENSIVE!) that i can sleep like a baby, also my flat doesn't have like 40C all day because of the heat of the rigs (i remember when i had like 20 R9 280X here, Oh my, it wasn't the power consumption the problem, it was he HEAT, it was hell!!, even in winter, i had all the windows open, like -2C outside and 32 C inside, insane.

cheers

So whats your Ethereum mining efficiency with Nvidia? Lets see if we can top it with AMD Smiley

Hallo,
System:
6xSAPPHIRE NITRO+ RADEON RX 470 8G
ASRock H81Pro BTC 2.0 Mainboard LGA 1155
Intel Celeron G1610, 2x 2,6GHz
4 GB RAM
Super Flower - Leadex Titanium 1600W Netzteil
Windows 10
Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v9.1

I measure the power consumption with a calibrated electricity Watt meter
691 Watt / 168,5 MHS
-> 4,1 Watt / MHS

get someone  better efficiency?

I have long been obsessed with maximum efficiency over pushing my cards to the max.
To that end I managed to get to 4 W/Mh a long while ago on all my systems, and have also ran systems at 3.9 for a while with even tighter under-volt, but they restarted several times a day.

Same components as you with Gold psu's instead of titanium

I get 160 Mh @ 640W from the wall (actually hovers between 635 W and 640 W as the cards on the fan spin up and down)

Your Move ...

Instead of just bragging about configurations and results, what about sharing some knowledge about how you reached those levels?
the 1600 watt psu is part of his efficency results,  under 50% load hes probably gsining another 50 watts in savings compared to most ppl who run a 1k watt psu

I think it is not that big. With 2% difference, it is about 20W.

I just get 175 MH/s @ 840W from wall (130W per 1070 shown by nvidia-smi) - might get it down another 40-60W but not down to 700W  Shocked

5 x 570

140MH/s /  530watts  = 3.78w /Mhs   (All system)
