MSI Pro B860M-E DDR5 Intel Motherboard

The MSI Pro B860M-E DDR5 is a Micro ATX motherboard built around the Intel B860 Express Chipset and LGA1851 socket, designed to support Intel Core Ultra Series 2 processors. Measuring 24.4 cm × 21.5 cm, it fits standard Micro ATX cases while delivering a feature set suited to professional workloads and productivity-focused builds. Memory performance is a headline strength: two DDR5 UDIMM slots accommodate up to 128 GB of RAM, with JEDEC speeds ranging from 4800 to 6400 MT/s and overclocked (OC) profiles reaching 9066 MT/s in single-rank, single-DIMM-per-channel configurations. The board supports Intel XMP 3.0, CUDIMM, and MSI’s Memory Extension Mode for further tuning headroom. Connectivity is covered by an Intel Wi-Fi 6E AX210 module — supporting 2.4 GHz, 5 GHz, and 6 GHz bands with Bluetooth 5.3 — alongside a Realtek Gigabit Ethernet controller. The back panel provides four USB 3.2 Gen 1 Type-A ports and two USB 2.0 ports, while an internal USB Type-C header adds USB 3.2 Gen 2 support for compatible front-panel connections. For expansion, a PCIe 4.0 x16 slot handles discrete graphics or NVMe SSDs, backed by a PCIe 3.0 x1 slot. Storage options include two M.2 connectors (PCIe 4.0 x4/x2, Socket 3, type 2280) and four SATA 6 Gb/s ports with RAID 0/1/5/10 support. Display output is provided through integrated Intel HD Graphics via one HDMI 2.1 port (up to 4096×2160 @ 60 Hz) and one DisplayPort 2.1 (up to 3840×2160 @ 144 Hz), subject to CPU support. Audio is handled by a Realtek HD Audio CODEC supporting up to 7.1-channel output with S/PDIF out. The board ships with a 256 Mbit AMI UEFI BIOS flash, hardware monitoring for voltage, temperature, fan speed, and water-cooling flow rate, plus Transient Voltage Suppressors (TVS) and Over Current Protection on USB, DDR, and CPU power rails. A 3-year manufacturer warranty is included.
