  • Channel SupportedDual Channel
  • Memory FeatureSupport up to 9066+MT/s (OC), Non-ECC, Un-buffered ,Clocked
  • PCI Express 5.0 x16Intel Core Ultra Processors (Series 2) 1 x PCIe 5.0 x16 slot
  • Ready for Intel Core Ultra Series 2 processors via LGA 1851 socket
  • Robust 16+2+1+2 power stages rated up to 90A each for stable delivery
  • DDR5 memory support up to 192GB and 9066 MT/s with DIMM Flex and DIMM Fit
  • WiFi 7 and Bluetooth 5.4 plus 2.5G LAN for fast wireless and wired connectivity
  • Two Thunderbolt 4 ports and multiple high-speed USB including 20Gbps front-panel header

Socket & Chipset

The board uses the Intel LGA 1851 socket and Z890 chipset, targeting Intel Core Ultra Series 2 processors. It delivers a 16+2+1+2 phase power design rated at 90A and 80A per stage, plus ProCool II connectors for stable delivery. Four DDR5 slots support up to 192GB at speeds beyond 9066 MT/s when overclocked.

Ideal Build & Limits

Suits enthusiasts building an advanced AI-ready desktop who need Thunderbolt 4, WiFi 7, Bluetooth 5.4, and 2.5Gbps LAN from the rear I/O. Five M.2 slots (one PCIe 5.0, four PCIe 4.0) and four SATA 6Gb/s ports cover high-capacity storage. Builders needing legacy PCI slots or a smaller form factor should consider other models.

Deciding Spec

The defining specification is the LGA 1851 socket paired with the Z890 chipset, which only accepts Intel Core Ultra Series 2 CPUs. If your processor uses a different socket, this motherboard will not work. Verify CPU compatibility before purchase.
