Combo platform

This bundle pairs the MSI PRO X870E-P WIFI motherboard with the AMD Ryzen 9 9900X3D processor on the AM5 socket. The board uses the X870E chipset and supports Ryzen 7000, 8000 and 9000 series CPUs. Four DDR5 slots accept up to 256GB in dual channel mode. It is built for builders who want a ready matched CPU and board.

DDR5 ceiling

Memory overclocking headroom is defined by the CPU and slot population. With one single rank DIMM per channel the board can reach 8200+ MT/s, while two ranks per channel top out at 6400+ MT/s and two populated channels at 5600 MT/s. JEDEC speeds run from 4800 to 5600 MT/s. Choose your kit based on the target frequency and rank layout.

Thermal and power profile

The CPU has a 120W TDP and uses TSMC 4nm Zen 5 architecture with 128MB L3 cache. The motherboard provides a 60A SPS VRM design and Frozr AI Cooling that monitors CPU and GPU temperatures to adjust fan duty automatically. Onboard M.2 Shield Frozr heatsinks cover the three M.2 slots. Radeon graphics are integrated on the processor.

Questions about this item

What does the DDR5 8200+ MT/s overclock figure mean for real-world memory speed?

With a single rank kit in one slot the board can push past 8200 MT/s; two ranks in one slot top out near 6400 MT/s and populating all four slots reduces the ceiling further.

How fast is the Wi-Fi 7 link and what caps it?

The 320 MHz channel enables up to 5.8 Gbps, but actual throughput depends on router capabilities, channel congestion and client hardware support.

What clearance does the 60 A SPS VRM heatsink need for a CPU cooler?

The VRM heatsinks sit close to the AM5 socket; choose a cooler with a cut-out or offset base so it does not contact the VRM fins.
