Motherboard & CPU Combo for AM5 Builds

This bundle pairs the MSI MPG X870E EDGE TI WIFI motherboard with an AMD Ryzen 9 9900X processor. It targets enthusiasts assembling a high-end desktop on the Socket AM5 platform. The combination delivers a ready-to-run foundation for demanding workloads and gaming.

256GB DDR5 Capacity with 8400 MT/s Headroom

Four 288-pin slots accept up to 256GB of DDR5 memory. With Ryzen 9000 series processors the board can reach 8400 MT/s in a single-rank single-DIMM-per-channel configuration. JEDEC speeds settle at 5600 MT/s, while dual-channel operation remains the standard topology.

12-Core Ryzen 9 9900X with 5.6 GHz Boost

The included CPU provides 12 cores and 24 threads based on the Zen 5 architecture. It offers a maximum boost frequency of 5.6 GHz, 64 MB of L3 cache and unlocked multipliers for overclocking. This processor defines the performance ceiling of the combo.

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.
