I've switched from win10 to nvOC as I was heaving issues with windows hanging from time to time and I have couple questions:

1. I have 3 1060 from different manufacturers and when I set power limit to anything from 70W to 84W it works on 2 of them but the third one, which is palit, is running always at 94W and it won't get lower, is this something limited by cards bios?
2. In windows with latest drivers I'm getting 22.5-22.8 Mhs in eth per gtx1060 using Claymores miner but in nvOS I'm getting 21Mhs with exactly same settings (core +120, memory +700, PL 84W) Is this typical for eth because of how Claymore wrote his miner for linux or simply I should look for different settings because of OS/driver differences?



nvidia-smi -i 0 --query-gpu=power.min_limit,power.max_limit --format=csv
where -i "number" is the gpu you want to query
regarding second question, I am also seeing discrepancies, try higher overclock or higher PL
also, go for 378 driver!

I have 378 driver already installed and the command provided returns 60W for minimum power limit and 140W for max
here is the screen from nvidia-smi command showing all gpus with low power limit set:

When comparing power consumption; even within the same OS the software is not accurate.  With some brands the information from Nvidia-smi is almost correct, with others it is very off. 

When comparing Afterburner settings from windows with linux powerlimits; you need to know the TDP of the card you are using.  This varies by manufacturer and the specific card model.  Afterburner uses percent TDP while linux powerlimits are implemented in watts.  The 1060 3gb I have have a TDP of 120 watts.  Thus 84 % of 120 is 100.8 watts: this would be the linux powerlimit equivalent of a windows afterburner powerlimit setting of 84.

To have accurate comparisons you really need to have a device such as a kill-a-watt, that will measure the power-at-the-wall.  Tell me if a 101 watt powerlimit in linux produces similar hashrates.


I have the rig connected to smart plug which shows power usage and all my cards have 120W TDP. In AB I set all cards to 70% which gives me 84W per card + efficiency of PSU and setting 84W in linux produces ~10W more for entire rig power consumption.

If you set the linux power limit so that the actual power-at-the-wall matches what it is with windows; how do the hashrates compare?
