Subject: Idle CoreParking vCore // 1700x+X370TaiChi
Posted: 09 Aug 2019 at 7:50pm
Ryzen 1700x
X370 TaiChi BIOS P3.10
Windows 10 Pro x64 v1803
I am using a slightly tweaked Windows Balanced power profile, it's more towards power saving than being responsive ala the "Ryzen Balanced" profile.
Something strange happens with my system regards Core Parking and vCore.
After boot up and stabilisation, at some point seemingly at random, CoreParking gets disabled (cores no longer park as shown in Task Manager) and both RyzenMaster and HWiNFO show SV12 TFN jump from the usual idle 0.8v to around 1.20v minimum. This vCore is also reflected in what is coming from the VRM
No matter what I do I cannot get the system to park cores again, or the vCore to drop to it's previous low sub-1v idle level.
I have to action a reboot and then things seem to be stable.
So this generally happens at some random time on the first boot after a cold start. A reboot seems to fix the behaviour and it doesn't happen again until the next time it's booted from cold (the next day).
Temperatures don't look to be drastically rising, but maybe they are a couple of degrees higher than they would be. With an NH-U14s things stay pretty cool anyway.
I've added ParkControl to my system tray to alert me when Core Parking seems to stop.
Any clue what is going on?
