Performance
Digital Power Design
Stable power is crucial for maximizing the performance of Intel® Core™ Ultra Processors (Series 2).The PRIME B860M-K features an 6+1+1+1 phase design with discrete MOSFETs,ensuring efficient and stable power delivery for Intel® processors plus steady performance for day-to-day use.
Enhanced Memory & Storage Performance
AEMP III for Ultimate DDR5 Performance
ASUS Enhanced Memory Profile III (AEMP III) is an advanced firmware feature that empowers users to achieve unparalleled memory performance with cutting-edge CUDIMM memory. Through a two-phase comprehensive tuning process, AEMP III first optimizes the clock driver and then the memory frequency. This results in the best balance between performance and stability, even at cutting-edge speeds of DDR5-7600 or higher.
DIMM Fit
DIMM Fit is an ASUS-exclusive BIOS feature that precisely analyzes individual memory modules to optimize performance and pinpoint potential issues. This offers peak efficiency, compatibility, and system stability. Whether you are an overclocker seeking ultimate performance, a competitor pursuing the most responsive gameplay, or a content creator prioritizing rock-solid stability, DIMM Fit provides optimizations tailored to your needs and your hardware configuration.
Two M.2 slots (up to 128Gbps)
PRIME B860M-K offers a total of two M.2 slots, including one that supports data-transfer speeds of up to 128Gbps via PCIe 5.0, one that supports 64Gbps via PCIe 4.0. This enables quicker boot-up and app load times with OS or application drives.
