Load line droop is an inherent part of Intel's power delivery design. Droop can help to reduce the output-voltage spike that results from fast load/current demand changes.

But in some situations, this will limit users ability to overclock their processor. In the GIGABYTE X58 Series BIOS, users can turn on and off this setting in order to control the load line drooping. This is called Load Line calibration. With this feature turned on, it will automatically fix the processor's vcore droop issue, and ensure the processor receives stable voltage during overclocking.
