ASUS ROG Crosshair X870E Extreme

The ROG Crosshair X870E Extreme is ASUS's absolute top-tier AM5 board, an E-ATX design with dual 5G and 10G LAN, a built-in 5-inch LCD display, and a vapor chamber SSD cooler, positioned as ASUS's direct answer to the MSI MEG X870E Godlike for buyers who want the single best AM5 board ASUS makes.

ASUS does not publish an exact phase count for this board on its specification page, but independent reviews confirm it uses a heavily reinforced VRM design suitable for extreme overclocking and sustained Ryzen 9000 X3D operation. Four DDR5 DIMM slots support up to 256GB total capacity, with overclocked speeds rated up to 9000+ MT/s on Ryzen 8000 series and 8200+ MT/s on Ryzen 9000 series processors. Two PCIe 5.0-capable x16 slots support x16, x8/x8, or x8/x4/x4 configurations. Storage covers three primary M.2 slots up to PCIe 5.0 x4, plus two additional PCIe 4.0 x4 slots via the included Q-DIMM.2 module and a SlimSAS connector for further expansion. Dual LAN combines a Realtek 5Gb controller with a Marvell AQtion 10Gb controller, alongside Wi-Fi 7 (802.11be) rated up to 6.5Gbps. Audio uses ASUS's ROG SupremeFX ALC4082 codec with 7.1-channel surround. Against the MSI MEG X870E Godlike in this batch, the Crosshair X870E Extreme offers a similar flagship feature set with a built-in LCD display as its signature differentiator, while the Godlike counters with its expandable seven-M.2 storage via the Xpander-Z card.
