To save power: turn off PCIE PHY of root (CPU) and endpoint (GPU) when no active link is needed (video output turned off).
ASPM for GPU can't degrade graphical performance, because OS kernel scheduler decides when to turn off the PCIE link, if inside processes list there is at least one process with opened PCIE session, those particular link won't be shutted down.
C states control registers are inside SOC Core (in each core), ASPM control registers are inside SOC Uncore. There is no connection between them.
My major reason for opening the thread, is because looks like there is some bug that shouldn't exist. Since there is no such problems on Asus Z170 series, I may conclude that Asus MBs quality is degrading, and I should reevaluate my future MB purchase.
