I undervolted my CPU about a year ago and haven’t had any issues with it till now. I’ve been dual booting Linux recently and noticed whenever I was in Linux it would crash/reboot after a couple of hours or less of using it. I noticed the behavior was similar to when I set the voltages too low when initially setting up the undervolt so I disabled it and haven’t had any crashed since. Any idea why it would be stable on Windows but not Linux? I tried a couple of different distros as well. I’ll probably just raise the voltage until I get it stable again but I’m interested to know what could cause this! If its relevant my CPU is a Ryzen 7 3800x

    It might run a bit cooler if its not always boosting

    I’ve heard that amd_pstate is a lot more power efficient (thus cooler) compared to acpi.

    Like I believe amd_pstate has a lot more states than acpi-cpufreq so it gives Linux much more granular control over the CPU’s performance.

      I can validate that. Switched my NAS to amd_pstate, went from 2.12 kW.h per day to 1.95 kW.h per day.
