bumping thread...

I just got a setup stable mining @30/card (ethereum only), but seems to be consuming ~140w/card. Anyone have similar numbers at lower wattage? Thought these things would mine high 20's at 80 w?

one click bios

1200 core
877 mv
2100 memory

~140w per card seems a bit much.
Have you undervolted both core and memory?
If not, try undervolting memory to 900mV, and if it's stable, try lowering voltage until you find max undervolt.
On this link there is tutorial how to undervolt using OverdriveNtool https://mining.help/

He uses 877mV.
If you undervolt memory to 900mV you can save like 10W at wall, depends on memory type with Samsungs you can go even to 850mV or with most of them. Under 100W with RX 5xx you can go only when you mine Monero and other CN coins. Not really with ETH.
Go below 1180MHz and try 800mV you should be hitting 120W or maybe a bit higher like 820mV depends on card.
Overdriventool is great.

Thanks; got to roughly ~120w/card after compensating for losses @ the power supply.
1150
850mv
2100 memory
mostly hynix, one elpidia

Simple mining nor Hive have memory undervolting option so may have to try the overdriventool.
