Are there any planned changes coming for the power limit configuration? This might be the one reason I switch back to Windows as my rigs now each use around 200W more than windows.

RX 580 4GB is having issues. Anything under power limit/stage 4 gives terrible hashrate and some cards stop mining.

Same problem here, I have 27 RX580 NITRO+ 8G. Undervolt on Linux does not work, either on Ethos or SMOS. I also had to go back to Windows and remove one GPU from each rig to be 8 GPU each rig. All Linux OS, "globalpowertune 4" not work with double mining (card stop) and suck to much power anyway, 5 is beyond too much power.

The whole purpose of having a Linux operating system is to recognize all the GPUs and do the undervolt, but the system can not, so the whole purpose for using Linux ends here.

I work for a company that wanted to buy 100 Ethos licenses or use SMos, was all cancelled to use Windows

I think you can try to write moded undervolted BIOS to cards for Linux ethOS or smOS.

You could do this... I prefer realtime undervolting on Linux, however, which *is* in fact possible (NSFW): http://i.imgur.com/1UEGeRz.jpg

Did you do undervolt on bios or on Linux? Can you tell me what parameters you used on the rx580 nitro +? thank you
