VR Zone has written a guide on modding the load line regulation and over current protection of the Gigabyte GA-H55N-USB3, a popular Mini-ITX board for overclockers.
When the GA-H55N-USB3 is used in conjunction with high core-count or overclocked processors, the ISL6334 buck controller will compensate for the increased ohmic losses within the VRM output filters so long as Load Line Calibration is enabled. This is a useful feature for most overclockers. However, at even higher clock speeds or processor core-count, the load line regulation applied by the BIOS may fall outside specifications. It is therefore be necessary to introduce some deliberate droop to prevent overshoots (that can lead to premature overcurrent trips) or undershoots in the VRM output.
Two simple modifications can be made to customise the VRM load line regulation to your needs. Before that, it would be good to check if your load is responding well to the built-in "Load Line Calibration" settings.
