Mine ranges from 30.0 to 30.3 eth and 750-760 dcr @145-150w across all 8 cards.
1160/2025/875 with dcri25.

Electricity costs much for me so I prefer the lowest possible consumption.

I can get to the numbers (performance wise) that you posted but not with 145-150w. How did you measure that?

I use the following method for measuring gpu power draw:

Remove all gpus and risers from the rig. I mean unplug them completely
Measure idle consumption of the rig.
Reconnect all gpus and risers
Measure mining consumption of the rig.
Perform a mining - idle consumption and divide by the number of the gpus

Keep in mind that if you have your GPUs or risers plugged in (even without having them mining) they do consume power.
Also, I only measure power consumption using a wall meter.

Did you use that methodology for your measurements @greatauror28 ? What brand of RX 580 do you have?

Hey!

I have 8x Sapphire Nitro+ cards. I do get that the cards do consume even when not minining. I do have the TPLink-HS110 smart plug and the Kasa app on my iphone. When no cards are plugged and system is on, it pulls 53w. When I have all 8 cards dual-mining, it's pulling around 1240-1260w at the wall.

(1260-53)/8 = 150.875w per card.

I have both cvddc and mvddc set at 875mV and as per HWinfo, they average from 850 to 865mV when running.

If you want to consume less, try lowering your dcri value from 30 to 25 like mine. It'll lessens your dcr hashrate but should save you around 5-8 watts per card.

I have posted it before
