Overview

This ATX motherboard pairs the Intel B860 chipset with the LGA 1851 socket for Arrow Lake processors. It suits gamers and builders who want PCIe 5.0 speed without CPU overclocking.

Design and Cooling

The board uses a black ATX layout measuring 305 by 244 millimeters. It includes a built-in I/O shield, VRM heatsinks, M.2 heatsinks, and a backplate for structural rigidity.

Performance and Memory

Four DIMM slots accept UDIMM or CUDIMM modules up to 192GB total. DDR5 can be overclocked to 8200 MT/s via Intel XMP 3.0 profiles. ECC memory is supported for data integrity.

Storage and Expansion

One PCIe 5.0 x16 slot runs at full x16 speed without lane splitting. A second PCIe 4.0 x16 slot operates at x4. Storage includes one PCIe 5.0 M.2, two PCIe 4.0 M.2, and four SATA 6G ports.

Connectivity and Included Features

Rear I/O provides 2.5G LAN, DisplayPort, HDMI, and five USB Type-A ports plus one USB-C 3.2 Gen 2 port. Internal headers add USB4, USB 3.2 Gen 1 Type-C, multiple USB 2.0, RGB and addressable RGB connectors, front audio, and SPI TPM.
