No laptop in existence lets you change LLC (Loadline calibration). It's always hardwired to the SKU defaults.
DC Loadline Override (mOhms) which is hidden in CPU Overclocking Menu is supposed to control Loadline Calibration, according to AMI, but not even Clevos have it hooked up to anything. Since there's no vcore sensor (all laptops use VID override, which is NOT the same thing, when you use "Fixed" voltage), the only way to even know if DC Loadline Override (mOhms) is doing anything is to look at temps and power consumption after the change (temps work best), but one person tested it in a recent MSIbook and another on a DTR Clevo, and the values weren't wired to anything.
AC Loadline controls the VID response to the VRM, which helps set vcore before the hardwired LLC vdroop takes effect. It's rather a simple formula too:
vCPU=CPU base VID (depending on multiplier). Override voltage rewrites the base VID with the override value.
Vcore=vCPU + (AC Loadline mOhms * Amps) - (LLC mOhms*Amps) +vOffset, with LLC usually hardwired to 1.8, 2.1 or 1.6 mOhms.
"VID" shown is vCPU + AC Loadline mOhms * Amps - (DC Loadline mOhms * Amps) +vOffset
The displayed VID is also affected by DC Loadline, but DC Loadline doesn't affect vcore (ok, it does in a very small way; seems to be a 15mv difference between DC Loadline=0.01 mOhms and 1.6 mOhms, but "VID" will differ drastically between these two values. At least that's from what I saw on my Z390 Aorus Master, when looking at VR VOUT.
On desktops, using a fixed vcore bypasses AC Loadline completely (VID will still be affected by it).
