Questions about this item

Will my existing DDR5 modules rated at 8000 MT/s reach that speed with the Ryzen 9 9900X3D on this board?

The board supports DDR5 up to 8000+ MT/s (OC) with Ryzen 7000 series processors, so 8000 MT/s modules should reach their rated XMP or EXPO profile.

How do I confirm the 18+2+2 power stages and Wi-Fi 7 are active after first boot?

Enter the UEFI and check the AI Overclocking and AI Networking sections; the dashboard shows power-stage status and the Wi-Fi 7 (802.11be) link rate when connected.

What cooling parts come in the box for the five M.2 slots and do I need extra heatsinks?

All five onboard M.2 slots — three PCIe 5.0 and two PCIe 4.0 — include substantial heatsinks pre-installed on the motherboard, so no additional M.2 cooling is required.
