Z890 chipset ATX motherboard

The ASRock Z890 Lightning WiFi is an ATX motherboard built for Intel Core Ultra Series 2 processors on the LGA 1851 socket. It targets enthusiasts who want a high-end platform for gaming or content creation with extensive overclocking headroom. The board delivers a 18+1+1+1+1 power phase design using 80A SPS stages and 20K capacitors rated at 1000uF for stable delivery under heavy loads.

DDR5 memory and PCIe 5.0 expansion

Four 288-pin DDR5 slots support dual-channel kits up to 256GB with XMP 3.0 profiles reaching 9466 MT/s in 1DPC 1R configuration. The primary PCIe 5.0 x16 slot connects directly to the CPU for graphics or riser cards, while the chipset provides a PCIe 4.0 x16 slot at x4 and a PCIe 4.0 x4 slot for additional add-in cards.

Triple M.2 with Gen5 primary

Storage includes one CPU-attached M.2 2280 socket at PCIe 5.0 x4 (128 Gb/s) and two chipset-attached M.2 2280 sockets at PCIe 4.0 x4, all with RAID 0, 1, 5 and 10 support alongside four SATA 6Gb/s ports. Upgrading from a Z790 board brings the new socket, DDR5 speeds beyond 8000 MT/s and a Gen5 M.2 slot, making the jump worthwhile when moving to Core Ultra Series 2 CPUs.

Highlights

  • Supports Intel Core Ultra Series 2 processors on LGA 1851 socket
  • 18+1+1+1+1 power phase design with 80A SPS for stable CPU delivery
  • Four DDR5 slots up to 256GB with XMP 3.0 support to 9466MHz

Questions about this item

How much power can the 18+1+1+1+1 phase VRM with 80A SPS deliver to the CPU VCore under sustained load?

The 18+1+1+1+1 power phase design with 80A SPS per phase is rated for high current delivery to the CPU VCore, GT and SA rails, with 20K capacitors rated at 1000uF for lower ripple and stable output under heavy loads.

What are the thermal characteristics of the VRM heatsinks and chipset cooling when the board runs all day at high current?

The VRM uses upgraded 20K Black capacitors with 1000uF capacitance rated for 20000 hours lifespan, designed for lower ripple and more stable current output during extended high-load operation.

Which DDR5 memory speeds are natively supported without overclocking on the four 288-pin slots?

The board supports DDR5 5600 MHz natively in 1DPC 1R and 1DPC 2R configurations, and DDR5 4800 MHz natively in 2DPC 1R configuration across the four DDR5 slots.
