CPU_PHASE
These LEDs will change according to CPU loading. The higher the power phase number, the more reliable the power flow to the processor.
CPU_SA_PHASE
These LEDs indicate the current CPU System Agent power phase mode.
CPU_IO_PHASE
These LEDs indicate the current CPU I/O power phase mode.
PCH_PHASE
These LEDs indicate the current PCH power phase mode.
DrMOS_ALARM
This LED will light when DrMOS overheat.
DDR_PHASE
These LEDs indicate the current memory power phase mode.
HDD_LED
This LED will flash whenever there's a disk activity.
CHB/ CHD_DIMM_WARNING
These LEDs will light when the installed memories in channel B (DIMM3/ DIMM4) and channel D (DIMM7/ DIMM8) do not meet the mainboard design.
