Performance

Robust power design
Stable power is crucial for maximizing the performance of Intel® Core™ Ultra Processors (Series 2). The PRIME B860M-A WIFI-CSM is designed to meet the needs of high-core-count CPUs. It features 7(80A) + 1(80A) + 1(80A) + 1(80A) power stages that integrate high-side and low-side MOSFETs and drivers into packages rated for up to 80 amperes each. This configuration ensures optimal power delivery, efficiency, stability and performance for both current and future Intel® processors.

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 Pro
DIMM Fit is an ASUS-exclusive BIOS feature that precisely analyzes individual memory modules to optimize performance and pinpoint potential issues. DIMM Fit Pro gives advanced PC builders more extensive customizability for memory tuning. It allows users to control up to twenty overclocking parameters, define testing ranges, and prioritize stability or performance, offering a more flexible and granular approach to memory optimization.

Two M.2 slots (up to 128Gbps)
The PRIME B860M-A WIFI-CSM 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.
