AM5 Motherboard with Ryzen 9 9950X

This combo pairs the ROG Crosshair X870E Dark Hero board with a Ryzen 9 9950X processor in the AM5 socket. It targets builders who want a high-end platform for AI workloads, heavy multitasking and enthusiast overclocking. The board delivers dual-channel DDR5 support, dual 10 Gbps and 5 Gbps Ethernet, Wi-Fi 802.11 be and Bluetooth 5.4.

256 GB DDR5 Capacity and Five M.2 Slots

Four 288-pin slots accept up to 256 GB of DDR5 memory, with rated speeds reaching 8600 MT/s on Ryzen 9000 series and 9600 MT/s on Ryzen 8000 series. Storage includes two PCIe 5.0 M.2 slots for 2242, 2260, 2280 or 22110 drives and three PCIe 4.0 M.2 slots, all cooled by substantial heatsinks including a 3D vapour-chamber unit on the primary slot.

Upgrade from Older AM5 or AM4 Builds

The combo replaces an earlier AM5 motherboard or an AM4 system that lacks PCIe 5.0 graphics and storage lanes, dual USB4 40 Gbps ports and the 20 plus 2 plus 2 110 A power-stage design. The jump is worthwhile when you need the higher memory headroom, the extra 5.0 M.2 slot and the ROG overclocking toolset such as Dynamic OC Switcher and Core Flex.

Questions about this item

Will my existing DDR5 memory kit run at rated speed with the Ryzen 9 9950X installed?

The board supports up to 8600+ MT/s (OC) with Ryzen 9000 series processors. Your kit's rated frequency and voltage must fall within the supported range and the motherboard's QVL for stable operation.

How can I confirm the AI Cache Boost feature is active after first boot?

Enter the UEFI BIOS and navigate to the AI Overclocking or AI Cache Boost section; the feature status will show as enabled. You can also monitor cache frequencies and latency improvements in the ROG dashboard software within Windows.

Does the package include a mounting bracket for the 3D VC M.2 heatsink on the primary PCIe 5.0 slot?

The 3D VC M.2 heatsink is integrated onto the motherboard for the M.2_1 slot. The combo includes the motherboard with pre-installed I/O shield, the Ryzen 9 9950X processor, and standard accessories like SATA cables and Wi-Fi antennas.
