Ok I pulled down AIDA64 and RealBench. I followed along in OC Walk through video.
CPU = 4Ghz
RAM = 2400 Mhz
CPU voltage offset = 0.02500
LLC = Level 1
I selected the 15 min. duration in Real Bench Stress test, using the full 16GB of memory, and started it up. In AIDA64 the core voltage peaked at 1.353 and fluctuated between the peak and 1.3330. I used Ai Suite to get temperature info. The CPU hovered at 64/65C and was a steady 36C at idle before the stress test was started. Room temperature was at 26.5C at the start of the stress test and rose to 29.2C by the end of the stress test (I'm using the Galaxy Sensors app on my phone). I don't know if this would be considered strange but at about 3-4 mins. after the stress test ended (it passed), the CPU voltage jumped to 1.373, and then 1.395, and then went back down to 1.352. I had like 1-2% CPU utilization going on... basically idle.
I also grabbed Ryzen Master and Hardware Info 64. For anyone interested here is demo vid of Ryzen Master =>
