[Question] What does the System Agent setting undervolt #40

Hey,

Thank you for providing this tool. I'm currently experimenting with various settings, but I'm struggling to find details on what the System Agent undervolts. Could you please clarify on what's happening?

Cheers

The Throttle Stop Q&A websites(like here) said that System Agent is something like memory controller and PCIe controller, which comsumes little power, and better leave untouched. I've slightly undervolted it and didn't see any difference(like power comsumption).

System agent is a northbridge replacement integrated into CPU die. Sometimes it's also called "uncore".

There is some mess if you want to understand what actually this setting undervolts, though.
