It works but, as I've said on SMOS thread, using roc kernel and changing boot parameter makes power consumption goes from 1150W to 1550W (on the wall, at least on my rx580 rig). Have you checked your power consumption after this change?
I use roc kernel on smos and consume it is the same, maybe you changed power step (consume is setup at level of bios of gpu, i have steps from 2 to 7 to my target voltage), check them on console.
