ASUS ROG CROSSHAIR X870E HERO AMD motherboard

SKU CH-NCDX-S67Y9 MPN ROG CROSSHAIR X870E HERO

An AM5 ATX board with 18+2+2 power stages, DDR5 to 8600+ MT/s, three PCIe 5.0 M.2 slots, Wi-Fi 7, 5 Gb and 2.5 Gb Ethernet, USB4 and AI overclocking tools

  • CPU Socket TypeAM5
  • CPU TypeRyzen 7000 Series / Ryzen 8000 Series / Ryzen 9000 Series
  • ChipsetAMD X870E
  • Number of Memory Slots4x288pin (DDR5)
  • Memory StandardDDR5 4400 / DDR5 4800
  • Maximum Memory Supported256GB

Option ROG CROSSHAIR X870E HERO

  • AI-ready platform with AM5 socket for Ryzen 9000 series
  • 18+2+2 power stages rated at 110 A for stable overclocking
  • Three PCIe 5.0 M.2 slots plus two PCIe 4.0 M.2 slots
  • Wi-Fi 7 and dual Ethernet at 5 Gbps and 2.5 Gbps
  • USB4 and DDR5 support up to 256 GB capacity

AI-ready AM5 platform

The ROG Crosshair X870E Hero is an ATX motherboard built for AMD Ryzen 7000, 8000 and 9000 series processors. It targets enthusiasts who want extensive overclocking tools, AI-assisted tuning and a high-density feature set in a single board.

PCIe 5.0 and DDR5 limits

Two PCIe 5.0 x16 slots share bandwidth in x8/x8 mode when both are populated. Three M.2 slots run at PCIe 5.0 x4 speeds while two additional slots use PCIe 4.0 x4. DDR5 memory tops out at 8200 MT/s with Ryzen 9000 CPUs and 8000 MT/s with Ryzen 7000 CPUs.

Upgrade path from X870 and earlier chipsets

Moving from an X870 or 600-series board adds a second PCIe 5.0 x16 slot, a third PCIe 5.0 M.2 slot and dual 5 Gbps plus 2.5 Gbps Ethernet. The jump is worthwhile when workloads need maximum PCIe 5.0 lane count and the highest DDR5 frequencies.

Highlights

  • AI-ready platform with AM5 socket for Ryzen 9000 series
  • 18+2+2 power stages rated at 110 A for stable overclocking
  • Three PCIe 5.0 M.2 slots plus two PCIe 4.0 M.2 slots
  • Wi-Fi 7 and dual Ethernet at 5 Gbps and 2.5 Gbps
  • USB4 and DDR5 support up to 256 GB capacity

Questions about this item

Should I pick the 4400 MT/s or 4800 MT/s DDR5 baseline for my Ryzen build?

Both are JEDEC baselines; the board runs either at stock and can exceed 8000 MT/s with Ryzen 7000, 8600 MT/s with Ryzen 8000, or 8200 MT/s with Ryzen 9000 when overclocked.

What does the 18+2+2 power-stage design actually deliver to the CPU?

Eighteen 110 A Vcore stages plus two 110 A SOC and two auxiliary stages feed the AM5 socket through ProCool II connectors, giving headroom for sustained high-current loads.

How fast are the three PCIe 5.0 M.2 slots in everyday use?

Each of the three Key-M slots (2242/2260/2280) runs at PCIe 5.0 x4, so a compatible drive can reach the interface’s full 5.0 bandwidth.
