  • Supported memory2 x DIMM slots, max. 128 GB, DDR5 Supports up to 8200+MT/s(O

Model ROG CROSSHAIR X870E APEX

  • AI-ready platform built for demanding workloads
  • 18+2+2 power stages with 110A and 80A ratings
  • DDR5 overclocking up to 9600 MT/s with included memory fan
  • Five M.2 slots including three PCIe 5.0 and two on DIMM.2 card
  • Wi-Fi 7 and 5Gb Ethernet for high-speed connectivity

Target audience

The ROG CROSSHAIR X870E APEX is an AMD motherboard built for enthusiasts who want to push Ryzen 9000, 8000 and 7000 series processors. It uses the AM5 socket and X870E chipset with a 18+2+2 power stage design rated at 110A and 80A. Two DDR5 slots support up to 128GB and speeds beyond 9600 MT/s with the included memory fan.

Sustained load behaviour

Massive heatsinks linked by a heatpipe and high-conductivity pads keep the VRM cool during long rendering or compile sessions. The ROG Memory Fan kit actively cools the two DIMMs so DDR5 can hold 8200 MT/s on Ryzen 9000 or 9600 MT/s on Ryzen 8000 without throttling. Three onboard PCIe 5.0 M.2 slots and two more on the DIMM.2 card each have substantial heatsinks for steady throughput.

Upgrade path

This board replaces any earlier AM5 model that lacks PCIe 5.0 M.2 support, 5 Gb Ethernet or Wi-Fi 7. The jump is worth it when you need 9600 MT/s memory headroom, three native PCIe 5.0 x4 M.2 slots plus two more via DIMM.2, and USB4 connectivity for fast external storage.

Questions about this item

How hot do the 110 A power stages and 80 A power stages get when the board runs all day under full load?

Massive heatsinks with integrated I/O cover, high-conductivity thermal pads and a connecting heatpipe dissipate heat from the 18+2+2 power-stage array during sustained operation.

Which DDR5 memory kit do I need to reach the 9600 MT/s overclock shown for Ryzen 8000 series?

Two un-buffered DDR5 DIMMs up to 128 GB total; the board supports AMD EXPO and ASUS AEMP profiles, and the included ROG Memory Fan kit helps stability at 9600+ MT/s.

Will my PCIe 4.0 graphics card and SATA SSDs work in the PCIe 5.0 x16 slots and four SATA 6 Gb/s ports without adapters?

Yes — both PCIe 5.0 x16 slots with Q-Release Slim accept PCIe 4.0 cards at x16 or x8/x8, and four native SATA 6 Gb/s ports connect existing SATA drives directly.
