## Long description

Pro-A series is designed for enhanced stability, durability, and efficiency. This ATX motherboard with Intel LGA 1851 (Socket V1) supports DDR5 memory up to 256 GB across four DIMM slots, PCIe Gen5 M.2 storage, M.2 and SATA III RAID, integrated Realtek ALC897 7.1 audio and modern connectivity including Wi‑Fi 6E and 2.5 Gb/s LAN. The board features an aluminum heatsink, Hi‑Density power connector and a 10+1+1 power phase design with Dr. MOS to deliver stable power for daily computing and demanding workloads.
Advantages
The Hi‑Density Power Connector and 10+1+1 power phase design with Dr. MOS improve power delivery and thermal performance, which supports higher currents for CPU overclocking while reducing risk under heavy load. DDR5 XMP and AMD EXPO support allow easy memory overclocking using pretested profiles. PCIe Gen5 M.2 provides up to 128 Gb/s transfer speeds for next‑generation SSDs. Built‑in Wi‑Fi 6E and Dragon 2.5 Gb/s LAN offer faster wireless and wired networking respectively, and Polychrome RGB headers enable synchronized lighting with compatible accessories.

Form factor: ATX
Chipset: Intel B860
Audio: Realtek ALC897, 7.1 channels
Memory: DDR5, 4 DIMM slots, up to 256 GB; supports XMP and EXPO profiles
Storage: PCIe Gen5 M.2 (Blazing M.2), M.2 and SATA III with RAID support
Power design: 10+1+1 power phases with Dr. MOS and Hi‑Density Power Connector
Networking: Dragon 2.5 Gb/s LAN; Wi‑Fi 6E (802.11ax) and Bluetooth 5.3
BIOS: UEFI AMI, 256 Mbit
RGB: Onboard RGB and addressable RGB headers (Polychrome RGB)
How to use
Install the motherboard into an ATX‑compatible chassis and connect the Intel LGA 1851 CPU following the socket manufacturer instructions. Populate DDR5 modules in recommended slot order and enable the desired XMP or EXPO profile in UEFI to apply tested memory overclock settings. Mount PCIe Gen5 M.2 SSDs into the M.2 slot and configure storage modes (including RAID) in BIOS as needed. Connect power using the Hi‑Density CPU and 24‑pin ATX connectors, attach cooling to the aluminum heatsink areas, and install drivers for LAN, Wi‑Fi 6E and audio after the first boot.
Recommendations
Use compatible Intel LGA 1851 CPUs and DDR5 modules certified for XMP or EXPO to ensure system stability. Maintain adequate case airflow and quality CPU cooling to benefit from the power design and thermal features when performing sustained workloads or overclocking.
