Scheda madre ASRock B860M Pro-A micro ATX — Intel B860, LGA 1851, DDR5, 4 DIMM, fino a 256 GB, 2.5Gb Ethernet

ASRock B860M Pro-A is a micro ATX motherboard for Intel LGA 1851 (Socket V1) processors, designed to support Intel Core Ultra (Series 2). It offers four DDR5 DIMM slots with up to 256 GB memory capacity, multiple M.2 and SATA III storage options, PCIe 5.0 support for the primary M.2 slot, integrated 2.5 Gb/s LAN, modern USB Type-C connectivity and onboard RGB headers. The board targets compact desktop builds needing contemporary connectivity, solid power delivery and DDR5 memory overclocking support.

Advantages

The motherboard features a 10+1+1 power phase design with Dr.MOS and a hi-density CPU power connector to improve stability under high loads and overclocking. A 6-layer PCB and aluminum heatsinks enhance thermal performance and energy efficiency. PCIe Gen5 Blazing M.2 and USB 3.2 Gen2x2 Type-C provide high-speed storage and peripheral transfers, while dual graphics outputs (HDMI + DisplayPort) and reinforced PCIe steel slot increase versatility and mechanical durability.

How to use

Install the motherboard into a compatible Micro ATX case, fit an LGA 1851 processor and DDR5 memory modules into the four DIMM slots, and connect storage devices to the M.2 slots or SATA ports. Attach power using the hi-density CPU power connector and main ATX power connector. Connect display via HDMI or DisplayPort on the rear I/O, and plug USB Type-C/USB devices as required. Use the BIOS to enable XMP/EXPO profiles for DDR5 memory overclocking and update BIOS via BIOS Flashback if necessary.

Recommendations

For stable overclocking and heavy workloads, use high-quality power supplies and memory modules verified for Intel XMP or AMD EXPO. Ensure proper case airflow around the aluminum heatsinks and keep BIOS and network drivers up to date using the Auto Driver Installer.
