The ASRock B860M PRO RS is a Micro-ATX motherboard designed for Intel Core Ultra Series 2 processors using the LGA1851 socket. It features a 10+1+1 power phase design with Dr.MOS and a 6-layer PCB, providing a stable foundation for your hardware. You can install up to 256GB of DDR5 memory across four slots, supporting speeds of 8666+ MHz via overclocking through Intel XMP or AMD EXPO profiles. For storage and expansion, the board includes a reinforced steel PCIe 5.0 x16 slot for your graphics card and three M.2 slots. The primary Blazing M.2 slot supports PCIe Gen5 x4 speeds, while two additional Hyper M.2 slots use PCIe Gen4 x4, with a bottom heatsink to help keep drives cool during heavy use. Connectivity is handled by a Realtek 2.5 Gigabit Ethernet controller and a variety of ports, including a high-speed USB 3.2 Gen 2x2 Type-C port reaching 20 Gbps. Visuals can be routed through HDMI 2.1 or DisplayPort 1.4 outputs, while the Realtek ALC897 codec with Nahimic Audio manages your sound. To personalize the look of your build, you can use Polychrome RGB or SignalRGB across three addressable headers. Practical tools like BIOS Flashback and an Auto Driver Installer make the initial setup more straightforward for anyone building a modern, compact workstation or gaming PC.
