Intel Core Ultra Series 2 platform

The ASRock B860 Pro RS WiFi is an ATX motherboard built for Intel Core Ultra Series 2 processors on the LGA 1851 socket. It targets builders who want a modern mid-range foundation for gaming or content creation without stepping up to a Z-series chipset. The board delivers the essential connectivity and expansion these CPUs require.

256 GB DDR5 headroom

Four DDR5 slots accept up to 256 GB in dual-channel mode with XMP 3.0 profiles reaching 8666 MT/s. That capacity handles heavy multitasking and large project files comfortably, while the top overclocked speeds benefit memory-sensitive workloads. Everyday gaming and productivity run well within the standard JEDEC range.

Nahimic Audio and Dragon LAN

The Realtek ALC897 codec provides 7.1-channel output enhanced by Nahimic Audio software for spatial tuning and voice clarity. A Dragon RTL8125BG controller supplies wired networking, and the board includes Wi-Fi for wireless access. These integrated features reduce the need for separate sound or network cards.

Questions about this item

Can I reuse my existing DDR5 modules in the B860 Pro RS WiFi's four 288-pin slots?

The board accepts DDR5 non-ECC unbuffered DIMMs up to 8666+(OC) and supports Intel XMP 3.0 profiles on all four slots.

How do I verify the PCIe 5.0 x16 slot and the Blazing M.2 socket are running at Gen5 speeds after assembly?

Check the BIOS or OS device manager for a x16 link on PCIE1 and a Gen5x4 link on M2_1; both should report 128 Gb/s bandwidth.

Which cables or brackets are included and what must I source separately for the 4 SATA 6Gb/s ports and the three M.2 sockets?

The box contains the ATX motherboard, I/O shield, SATA cables, M.2 screws and documentation; drives and DDR5 memory are not included.
