I played around with voltages once again with my 3900x and in my opinion "auto" vcore is too high in 7106 and 7201. I get ~7150 points in CB R20 with auto vcore. temp is about 80°C while running CB but ~90-92 while running prime95. Noctuah NH-D15 with both fans. 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 is the key to lower temps?
