Can the load line calibration (LLC) affect your PSU or hardware?
Can the load line calibration (LLC) affect your PSU or hardware?
I wondered if applying this setting in high, ultra high or extreme conditions might harm your hardware.
LLC modifies the vCore offset during operation to achieve identical peak load voltages as choosing a higher vCore, while also enabling idle voltage levels similar to those without the adjustment. Ultimately, it serves mainly as a means for users who want to avoid appearing to apply excessive voltage to think they are using less. The only harm it can cause is overvolting the CPU itself.

Ultimately it serves as a utility mainly for users hesitant about excessive voltage usage, allowing them to perceive lower consumption than actual. The sole consequence of CPU overvoltage is damage to the CPU itself.
While those monitoring softwares are not fast enough to show the voltage spikes you see in the graphs, they should be showing the correct
average
voltages so when under load, you should be seeing a higher voltage with LLC enabled than without. But no change when at idle.
