Questions about this item

Will my existing DDR5 memory run at its rated speed with the Ryzen 9 9900X installed?

The board supports DDR5 up to 8400 MT/s overclocked with Ryzen 9000 series CPUs. JEDEC speeds of 4800 to 5600 MT/s are supported natively. Enable EXPO in BIOS to reach the kit's rated frequency.

How can I confirm the PCIe 5.0 x16 slot and the CPU-direct M.2 sockets are active after building?

In BIOS the PCI_E1 slot will show PCIe 5.0 x16 when a Ryzen 9000 or 7000 processor is detected. M.2_1 and M.2_2 run at PCIe 5.0 x4 from the CPU; M.2_3 and M.2_4 run at PCIe 4.0 from the chipset.

Does the combo include a CPU cooler, Wi-Fi antennas or mounting screws for the four M.2 slots?

The bundle contains the motherboard and Ryzen 9 9900X processor only. A compatible AM5 cooler, Wi-Fi 7 antennas and M.2 mounting screws must be purchased separately.
