This thread on reddit addresses my issue of popping(crackling) audio I occasionally encounter.

https://www.reddit.com/r/MSI_Gaming/comments/el6e8m/psa_audio_poppingcrackling_potential_fix_for/

But I don't see VDDG anywhere in my BIOS settings.  Additionally, would the recommended voltage increase be different since I have a Threadripper 1950X?

Is it the same as VDD_SOC in Command Center?

Fundamentally, XMP 3200 RAM overclock is just going to push your RAM voltage to 1.35. (DDR3 ran at 1.5V, so this "overvoltage" at 1.35 is quite safe and still relatively power-efficient). Your motherboard will also push the voltage on AMD's infinity fabric a bit higher (Vdd_soc to 1.1V).

Ok, it is the same as VDD_SOC.  I bumped mine to 1.200 from the default 1.150 setting and hopefully that'll put an end to the crackly/popping audio altogether.
