Socket LGA 1851 for Intel Core Ultra Series 2

This ATX motherboard uses the Intel Z890 chipset and the LGA 1851 socket to support Intel Core Ultra Processors (Series 2). It targets builders who want a stable platform for daily computing, gaming and content creation with room to grow.

16+1+1+1+1 Dr.MOS power phases and three M.2 slots

The board delivers power through a 16+1+1+1+1 phase design with Dr.MOS stages and 1000uF durable capacitors for clean, stable current under load. Connectivity includes one PCIe 5.0 x16 slot, two PCIe 4.0 x4 slots, one PCIe 4.0 x1 slot, four SATA 6Gb/s ports and three M.2 sockets — one CPU Gen5x4, two chipset Gen4x4 — plus Thunderbolt 4 Type-C and HDMI and DisplayPort outputs.

DDR5 up to 9066 MT/s and 256 GB capacity

Four 288-pin DDR5 slots run dual channel with native 5600 MT/s and XMP 3.0 profiles up to 9066 MT/s (OC), supporting 256 GB total. Realtek ALC897 7.1 CH HD Audio with Nahimic Audio handles sound. This board replaces older Z790 or Z790 platforms when moving to Core Ultra Series 2 and is worth the jump if you need PCIe 5.0 M.2, Thunderbolt 4 and higher DDR5 headroom.

Questions about this item

What PCIe generation and lane width does the primary x16 slot on the Z890 Pro RS WiFi use, and what bandwidth does that cap at?

The primary PCIe slot (PCIE1) runs at PCIe 5.0 x16, delivering up to 128 Gb/s of bandwidth for graphics cards or riser cards.

What physical space and mounting standard does the ASRock Z890 Pro RS WiFi require inside a chassis?

This board uses the ATX form factor and mounts via standard ATX screw holes; it also needs clearance for four 288-pin DDR5 DIMM slots and a 24-pin ATX power connector.

How is the CPU installed on the LGA 1851 socket, and which step do builders often get wrong?

Lift the load lever, align the processor notches with the socket keys, place it gently without pressure, then lower and latch the lever; the common mistake is forcing the CPU before the lever is fully open.
