Hello Jaz, that is perfectly normal and consistent with what your settings are. Raja has made a couple of very interesting replies re vdroop in another thread. You may find them useful.
I leave all my Speedstep and C states active so when my system processor is not being utilised 100% (9900K and Extreme board) my voltage of course drops to nearly nothing. 5GHz AUX on and I run at 1.224 vcore in CPUz. So really what is set in bios is not relevant to me when at rest or idle. What is relevent is vcore and temps under full load and at rest.
Nice system mate enjoy it.
