I've run out of Google and Bing results so I'm throwing this out there in case any of you brain-boxes know what these setting are, I've worked out what the other we're Gigabyte so lets use odd labels for voltages are but I'm stuck on what these three do.. CPU VDD18 CPU VDDP PM_CLDO12 If it matters this is on a X570 board and all I've found are recommendations for what to set them to but I've never really liked changing settings without at least understanding what they do.
