Technical Specifications

Compatibility & Important Information

• The motherboard uses the Intel LGA1851 socket and is specified for Intel Core Ultra Processors (Series 2); check the ASUS CPU Support List for the exact processor before purchase.
• Only DDR5 memory is supported. Memory speed and supported configurations depend on the installed CPU and DIMM configuration; ASUS provides a separate CPU/Memory Support List.
• WiFi 7 full functionality requires Windows 11 24H2 or later. ASUS states that Windows 11 21H2, 22H2 and 23H2 support WiFi 6E functionality, while 6 GHz availability varies by regional regulation.
• The board has one PCIe 5.0 x16 expansion slot, making case and graphics-card dimensions particularly important in Mini-ITX builds.
• M.2_1 supports PCIe 5.0 x4 drives in 2260/2280 sizes, while M.2_2 supports PCIe 4.0 x4 drives in 2242/2260/2280 sizes.
• Display resolution and motherboard video output capabilities depend on the installed processor's graphics capabilities.
• 7.1-channel audio output requires a chassis with a compatible front-panel HD Audio module.
