dual mining,
all RX580's 8gb Saphire Nitros and Gigabytes only, 6 cards / rig. Using the undervolt & OC functionalities of SMOS only, BIOS modded for only memory straps, but I had a friend of mine do it for me so I don't have his precise settings.
Undervolt for sure works better after the core undervolt + dag fix update, used in combination with low powerstage values. Energy consumption is lower and the rigs are cooler now after the last update, I'll try to get an exact voltmeter reading from the wall next time we are doing maintenance and post it here...
All the Best
Can you please inform about yours rig speed (for ETH and other), dual mine? eth+?, overclocking setup, undervolting setup?
AND a photo about your watt from wall if you have a meter.
AND it will be perfect the infos from your friend.
That will be help -hopefully- for other people and after that maybe can confirm a lot of smOS user confirm that everything is ok.
