Model Z890I AORUS ULTRA

  • Supports Intel Core Ultra Series 2 processors on LGA 1851 socket
  • DDR5 memory up to 8800 MT/s overclocked across two DIMM slots

Z890 Mini-ITX for Core Ultra Series 2

This LGA 1851 motherboard fits Intel Core Ultra Processors (Series 2) into a Mini-ITX footprint. It provides two DDR5 DIMM slots supporting up to 128GB in dual-channel mode. The board targets compact workstations and high-performance small-form-factor builds that need full Z890 feature density.

105A power stages with VRM armor

An 8+1+2 phase design uses 105A smart power stages to feed the CPU socket. VRM Thermal Armor covers the power delivery array to dissipate heat during extended multi-core workloads. M.2 Thermal Guard shields both M.2 slots, helping storage maintain throughput during sustained read and write sessions.

PCIe 5.0 x16 and Thunderbolt 4 limits

The single PCI Express 5.0 x16 slot delivers 16 lanes directly from the processor for graphics or accelerator cards. Thunderbolt 4 on the rear I/O provides 40Gbps signalling for external storage, displays or docks. Both interfaces share the CPU lane budget, so populating the x16 slot with a x16 device leaves no PCIe 5.0 lanes for additional high-speed add-in cards.

Questions about this item

Will this board fit in a Mini-ITX case and still clear a large CPU cooler?

The form factor is Mini-ITX, so it fits any case that accepts that size; the VRM Thermal Armor adds height around the socket, so check your cooler’s clearance specification against the board layout before buying.

Which memory kits are guaranteed to run at their rated speed without manual tuning?

The board supports DDR5 speeds from 5600 up to 8800 MT/s when overclocked; any kit with an XMP profile within that range will configure automatically once XMP is enabled in the firmware.

What do I need to add for a complete wireless and wired network setup?

WIFI 7 and a 2.5 Gbps LAN port are already integrated, so no extra network cards are required; just attach antennas for wireless and plug an Ethernet cable for wired.
