Your 12V rail sure is low. Barely within tolerances.
How are your case fans configured? I understand that case came with 3, have you moved them around? added more? Which way are they blowing?
You may want to adjust the way the case moves air now that you have a CLC in there. I found my best overall temps with all of the case fans blowing INTO the case, which provides better direct turbulence over the VRM heatsink and socket area, as well as effectively assists the radiator fan with positive pressure.
Did you turn off Turbo? (trying to set base clocks beyond turbo clocks would likely cause problems, never tried myself but exceeding 4.2ghz is where I would expect you to run into problems if you forgot to turn this off)
Did you turn off APM? (if available)
Are you using LLC? (some asus boards have a "buggy" LLC that causes instability, may have to turn it off or try try a different setting)
Keep in mind, that the voltage setting, is not the same as the actual voltage under load. Looks like you are dipping a little bit (but not too bad) from 1.425V (setting) to ~1.38V under a load. This is actually a pretty decently "tight" regulation and is likely reflective of a "good enough" LLC setting selection to continue on unless it is bugged. However, you may
get better results by increasing the aggressiveness of the LLC setting to tighten up this variance. (example: I achieve 1.44375V as a "setting" through offset voltage settings, under a load, with a "medium" LLC setting (it's different on Giga boards), this will sag to ~1.43V under a load, or only about a 0.014V variance.) Tighter variances from idle to load are nice but not necessary. You can overcome voltage sag by just turning up the voltage and get about the same results. I just prefer the "tightly tuned" option because it makes me feel better about it overall.
Seems unlikely that the chip could be "that bad." You're basically at the turbo speeds and voltage, there has to be headroom in these things otherwise they can't sell them. Usually there's 600-700+mhz worth of headroom above base clocks on zambezi with the default VID.
For the sake of fulfilling some curiosity and perhaps offering some additional insight, what does your motherboard report (in BIOS/UEFI) as the default CPU VID (with turbo disabled
, make sure to save/reboot if you disable turbo to get a "true" reading of the base VID)
