Noticed something else interesting. When I closed out Discord while iCue was running, my system properly set 4/8 cores to sleep and everything was perfect, voltages drop as they should. When I have Discord open with iCue, it keeps core voltage at 1.05-1.10 and only sleeps 2/8 cores. When I close iCue and Discord is running, behavior is perfect again and it sleeps 4/8 cores, voltages drop again. Guess they don't like each other?
None of my other programs seem to impact anything: Chrome (11 tabs open), Rainmeter, Spotify, LGS, 1Password, MSI Afterburner.
