Adding an -0.2v offset reduces both temps and performance dramatically. Only about 6300 points in CB.

Adding -0.1v seems to be ok. CB performance is down to about 7075 points with temps about 10°C less than with auto. Allcore frequency is about 25 MHz less on each core. I am currently running prime95 for 30min and allcore freq is constantly about 4033 MHz per core. Temperature is about 81.5°C

So with the Noctua NH-D15 beeing pushed to it's limits with auto vcore enabled, how should the stock cooler work/perform? I just can't image that this is the way AMD designed that thing. Must be an issue with the bios. Or maybe AGESA 1.0.0.3 is the key to lower temps?
That's all normal. The processor cores are insanely heat dense, much hotter per mm^2 than the 9900K's cores. Heat transfer/dissipation is only going to be more of an issue going forward.
