Socket LGA 1851 Mini-ITX board

The ASRock B860I WiFi is a Mini-ITX motherboard built for Intel Core Ultra Series 2 processors on the LGA 1851 socket. It targets compact workstations and gaming systems that need a full feature set in a small footprint. The Intel B860 chipset provides mainstream connectivity without overclocking the CPU itself. Two DDR5 slots support up to 128 GB of memory.

DDR5 8933 OC and dual M.2 under load

Sustained memory throughput relies on the 8+1+1+1+1 power phase design feeding the two DDR5 slots, which are rated for DDR5 8933+(OC) via Intel XMP 3.0. The CPU-linked Blazing M.2 socket runs at PCIe Gen5x4 for the primary NVMe drive, while the chipset Hyper M.2 socket adds a second Gen4x4 slot. Four SATA 6Gb/s ports support RAID 0, 1, 5 and 10 arrays. A 2.5 Gbps Dragon RTL8125BG LAN controller handles wired traffic.

Mini-ITX install notes and common issues

The board uses standard Mini-ITX mounting holes and a 24-pin ATX plus 8-pin EPS power layout. Only two DDR5 slots exist, so 128 GB requires 64 GB modules that must be non-ECC un-buffered DIMMs or CUDIMMs. The PCIe 5.0 x16 slot shares bandwidth with the primary M.2 when an NVMe boot drive is used. Rear I/O includes HDMI and DisplayPort for integrated graphics, plus 7.1-channel audio from the Realtek ALC897 codec.

Perguntas sobre este artigo

How much heat does the 8+1+1+1+1 power phase design produce when the board runs all day with an Intel Core Ultra processor?

The 8+1+1+1+1 phase SPS layout distributes load across multiple stages, keeping VRM temperatures lower during sustained workloads on LGA 1851 CPUs.

Which DDR5 memory kit must I already own to reach the 8933+(OC) speed on the two 288-pin slots?

You need a dual-channel DDR5 kit rated for 8933 MT/s or higher with Intel XMP 3.0 support; the board accepts non-ECC un-buffered modules up to 128 GB total.

Will my existing SATA 6Gb/s drives and PCIe Gen4 NVMe SSD work alongside the new PCIe 5.0 x16 slot and Gen5 M.2 socket?

Yes — four SATA 6Gb/s ports, one Gen4x4 M.2 (64 Gb/s) and one Gen5x4 M.2 (128 Gb/s) all operate simultaneously with the PCIe 5.0 x16 graphics slot.
