Unstable Memory Voltage?

HWiNFO64 shows my memory voltage varies a lot. Is my memory voltage really unstable or is it a sensor/software issue? My system is 100% stable. The +5V under motherboard sensor is stable at 5.04v to 5.08v.

This is unfortunately a monitoring problem observed on some DDR5 modules. The memory voltage should be stable but due to the limited design of DDR5 PMIC circuits (more precisely their ADC), monitoring of some voltages sometimes gives incorrect results. I have spent a lot of time trying to tweak this but it seems impossible to come up with a method that would work properly for all modules/PMICs.
