Primary Plane Current Limit
Configure the current limit of the CPU under Turbo Mode in ampere. A lower limit can
protect the CPU and save power, while a higher limit may improve performance.
Long Duration Power Limit
Configure Package Power Limit 1 in watts. When the limit is exceeded, the CPU

Memory Information

This option allows users to browse the serial presence detect (SPD) and Intel extreme
memory profile (XMP) for DDR4 modules.
Load XMP Setting
Load XMP settings to overclock the DDR memory and perform beyond standard
specifications.
BCLK Frequency
The CPU speed is determined by the CPU Ratio multiplied with the BCLK. Increasing the
BCLK will increase the internal CPU clock speed but also affect the clock speed of other
components.
DRAM Reference Clock
Select Auto for optimized settings.
DRAM Frequency
If [Auto] is selected, the motherboard will detect the memory module(s) inserted
and assign the appropriate frequency automatically.
