YES Chuck... that is definitely a problem. Assuming you've reflashed to the latest image (downloaded dicrectly from SmOS About Page) after formatting the USB/SSD drive first, let's make sure bios OC isn't overriding software OC. Googling your motherboard (MSI Z170A G45), I notice it has OC Genie II. I think by setting it to "Enable by Onboard Button" disables it when you don't push a button? IF it is set to "Enable by BIOS", then it is enabled. There is a setting called "My OC Genie GPU Voltage" that is default to Auto. What do you see when you click on it... percentage or actual V/mV? *** Or maybe this only affects the iGPU.
Also, I haven't mined with nVidia yet, but plan to. So this is a question for ALL nVidia users:
What's the benefit of setting power limit if you are already undervolting through core/memory offset?
Here you got the first photo shows the Missing Variables from Overclocking. I just started the rig to take the pictures and did not give it a chance to warm up. But you see in the left bottom of the picture the power usage for all 6 cards Once warmed up they all hit around 170 to 180 watts.
