Load-Line Calibration

notes:


----------------------------------


Load-Line Calibration is a feature added to boards that allows the board to compensate for vDroop (voltage sag that might otherwise make your clock unstable) under times of load. Different "levels" of LLC apply different variations of compensation to your chosen vCore when load is applied to the processor. vDroop in itself (or whatever you want to call this), is a specification that was designed with longevity in mind, with that little bit of sag during high loads (assuming stock EVERYTHING), buying more time, and better temperatures with the chip used. It is extremely relevant to overclocking, as droop can make a potentially stable clock, crash.

That said, LLC can sometimes work better than it was intended to, and you end up with vBoost. Where the compensation will greatly overshoot the selected vCore, and can possibly damage or overheat the chip. Such extremes as +150mV are common with LLC set to its maximum compensation level. Use it with care.
