I am mostly set with the main three components(processor, motherboard and memory). Below are some results on the Ryzen voltage and power.
MB: C6H (Asus Crosshair VI)
power:EVGA G2 850W
M.2 storage=GEN3 (960Evo)
PCIEX16_1 graphics=GEN3 (1080ti in nvidia surround with 3 displays)
memory: G-Skill TridentZ F4-3200C16D-16GTZB 2x8GB with Hynix M-die (2017 chips) at 3200-16-16-16-16-36, 1.395V DRAM, 1.1V SB, 0.693V termination VTTDDR
VDDCR LLC=Level1 to limit voltage spikes (thanks to Raja@ASUS for the oscilloscope chart)
CPU SOC = 1.15V
I kept all other variables in BIOS on Auto and kept SB voltage limited to 1.1V to make these results also transferable to other motherboards such as X370-Pro.
Memory speed will vary for others because this same memory ran at 3200-16 on X370-Pro with 0515 BIOS with 1800X and 2933-14 with 1700X. Same on C6H with 0702 BIOS: 2933-14 with 1700X and 3200-16 with 1800X. The identical pair (also F4-3200C16D-16GTZB) earlier batch only ran at 2400.
I did not vary front side bus (aka BCLK), Pstate, memory interlace or custom clock (FID/DID) to squeeze an extra megahertz for the same reason of results transferability as not all motherboards have these settings.
Windows10 (pre-Creators version) set to performance power plan
In the table below VCORE is CPU core voltage, power measured at the plug (Win idle,CPUZ_1,CPUZ_multi,CB15)
CB score is shown in parentheses after the power. Zero score means CB crashed. No score means it completed but was not recorded.
Some frequencies are repeated to see if power dissipation is more driven by voltage or by frequency.
all settings on Auto

Exorbitant power dissipation (pushing 300Watts for the computer) from overclock generates a puny gain of going from 1704 (92 Watts cpu load at 3900 MHz) to 1760 (176Watts cpu load at 4075).
A reportedly unstable 0702 BIOS ran fine and did not crash during these tests.
Cinebench is a harsher stress than CPU-Z. CPU-Z maxes all threads, but CB somehow piles on additional 30-40 Watts of power. I would like to know how CB does that.
Memory manufacturer and die type was read by Thaiphoon.
Power was measured with hardware (Cyberpower CP1350PFCLCD) wattage reading at the power plug and is typically +/-4W for the readings at Windows idle, CPUZ single core and CPUZ multicore are shown.
Example arithmetic to work out the per-core wattage at 1.275V 3900MHz: (218W-137W)/7= 11.5W per core in CPUZ_multi. 11.5*8=92Watts for the processor. Caveat: +/- 4-5W.
Fan_CPU, CPU_opt and AIO_pump were set to maximum to avoid power variation with temperature.
Prime95 for 24 hours was not run at each setting for time reasons. Feel free to run it on your Ryzen and post an update next month, that is if your Ryzen lasts.
BIOS 1102 (when it's released, presumably with AGESA 1004a update)
Windows10 (Creators update released yesterday) set to performance power plan
BIOS 1102 (with Win10C)
Ubuntu Linux 17.04 reportedly with Ryzen capability released today
would be nice if Asus R&D were to publish a similar format summary with their BIOS test versions (with caveat that individual results @ >3000 CPU and 2133 RAM will vary) using a simple reproducible methodology.
