ASUS ROG Maximus Z890 Extreme

The ROG Maximus Z890 Extreme is ASUS's absolute top-tier Intel Core Ultra Series 2 board, an E-ATX design with dual PCIe 5.0 x16 slots, six M.2 slots, and dual 2.5G/10G LAN, positioned as the direct Intel counterpart to the ROG Crosshair X870E Extreme on AM5.

ASUS does not publish an exact VRM phase count for this board, but it is built with the same extreme-tier design philosophy as the Crosshair X870E Extreme, intended for sustained Core Ultra 9 operation and aggressive memory overclocking. Four DDR5 DIMM slots (CUDIMM-capable) support up to 256GB total capacity, with overclocked speeds rated up to 9200+ MT/s. Two PCIe 5.0 x16 slots from the CPU support x16, x8/x8, or x8/x4/x4 configurations, plus a PCIe 4.0 x4 slot from the chipset. Storage covers six total M.2 slots: four standard slots plus two additional via the ROG Q-DIMM.2 expansion module. Dual LAN combines an Intel 2.5Gb controller with a Marvell AQtion 10Gb controller, alongside Intel Wi-Fi 7 rated up to 5.8Gbps. Audio uses ASUS's ROG SupremeFX ALC4082 codec with 7.1-channel surround. Against the ASUS ROG Crosshair X870E Extreme in this batch, the Maximus Z890 Extreme mirrors its extreme-tier positioning on the Intel side, offering the same E-ATX form factor and dual 10G/2.5G LAN setup for buyers who specifically want Intel's Core Ultra Series 2 platform instead of AMD AM5.
