my board hasnt got it yet, im on the presumably 125 microcode, its the latest beta bios for my MSI MEG Z790 ACE.
i use
https://www.cpuid.com/softwares/hwmonitor.html but there are others you can use like
https://github.com/LibreHardwareMonitor/LibreHardwareMonitor
you can probably get other paid softwares that can log this nicely but i just look at the max value of CPU voltage and CPU VID after having the hardware monitor software running all the time while the system is on
CPU lite load is a setting that should be exposed in your BIOS, but maybe it isnt? from what i understand CPU lite load the lower the number is, the less of a ramp up of CPU voltage you get when running light loads. the CPU needs voltage to ramp up clocks but a higher quality CPU can get by with less CPU lite load mode
you can just test it by setting it to a lower setting and then using the system normally, i think it should lock the OS if the CPU lite load mode is too low. mine was default 12, i lowered it to 9 or 8 i think? i havent tried lower when i saw it was out of the danger zone
