How to view live RAM Voltage?

I'm looking to check the current voltage being applied to my RAM. On Windows I use HWinfo64. I tried dmidecode -t 17 but it looks like those are just preconfigured values, not live ones. Is there any other option on FreeNAS to view RAM voltages?

Backstory: I've been suffering from instability on my Ryzen 1700 system for the past couple years, and just assumed it was the C-state bug that couldn't be fixed. But now, I have a Ryzen 2700 and it still suffers from instability, so I'm seeing if raising the RAM voltage from 1.2 to 1.35V helps, but I need a way to verify my RAM voltage has actually changed in the OS. The BIOS says it has but I'm not sure if I trust it, because dmidecode -t 17 returns the following:

Might this be better addressed in a FreeBSD forum given that FreeBSD forms the underpinnings for FreeNAS?

I'll do that as well. Was just wondering if anyone here had any ideas
