Socket LGA 1851 ATX motherboard

The MSI PRO Z890-S WIFI is built on the Intel Z890 chipset for Intel Core Ultra Processors Series 2. It fits a standard ATX chassis and provides four 288-pin DDR5 slots with a maximum capacity of 256GB. The board delivers a PCIe 5.0 x16 slot from the CPU plus additional PCIe 4.0 and 3.0 slots from the chipset.

Suited for high-memory DDR5 builds; not for

This board suits builders who need dual-channel DDR5 up to 8600 MT/s overclocked and 256GB total capacity. The 2.5Gbps LAN and Wi-Fi 7 with 320MHz channel width serve high-throughput networking. Thunderbolt 4 adds 40Gbps USB-C connectivity. The full-size ATX layout rules out small-form-factor enclosures.

PCIe 5.0 x16 from CPU decides GPU bandwidth

The primary expansion slot runs at PCIe 5.0 x16 directly from the processor, providing up to 128GB/s bandwidth for a graphics card. Three M.2 Key M sockets and four SATA 6Gb/s ports handle storage. Realtek ALC897 8-channel audio and RTL8125D-CG 2.5G LAN complete the I/O.

Questions about this item

What DDR5 memory speed and capacity do I need for the Z890-S WIFI to work?

The board requires DDR5 modules and supports JEDEC speeds from 4800 to 6400 MT/s, with overclocked speeds up to 8600 MT/s. Maximum capacity is 256 GB across the four 288-pin slots in dual-channel mode.

Will my PCIe 4.0 graphics card and PCIe 3.0 add-in cards run at full speed on this motherboard?

The primary PCI_E1 slot is PCIe 5.0 x16 from the CPU, so a PCIe 4.0 GPU will operate at its native 4.0 x16 speed. The PCI_E2 slot is PCIe 3.0 x1 from the chipset, matching older x1 cards exactly.

How can I confirm Wi-Fi 7 and the 2.5 Gbps LAN are active after building the system?

In Windows Device Manager the wireless adapter should list 802.11be and the RTL8125D-CG Ethernet controller should show a 2.5 Gbps link speed when connected to a compatible switch or router.
