Combo AM5 12 cœurs 8400 MT/s

The MSI MAG B850 TOMAHAWK MAX WIFI motherboard is paired with an AMD Ryzen 9 9900X processor. The CPU delivers 12 cores and 24 threads built on the Zen 5 architecture with a 5.6 GHz maximum boost clock. The board provides an 80 A SPS VRM design and four DDR5 slots supporting up to 256 GB at 8400+ MT/s when overclocked.

Idéal 12 cœurs DDR5 8400 OC

This combination suits builders who want a 12-core AM5 platform with strong memory overclocking headroom and 5 GbE plus Wi-Fi 7 connectivity. Users needing ECC memory or more than four DIMM slots should consider a different chipset.

VRM 80 A SPS DDR5 8400+ OC

The 80 A SPS power stage rating is the specification that defines the board’s ability to sustain high currents for the 12-core processor during heavy workloads and memory overclocking up to 8400+ MT/s.

Kysymyksiä tästä tuotteesta

Will my existing DDR5 memory modules work with this board at their rated speeds?

The board supports DDR5 up to 8400+ MT/s when overclocked and runs at 5600 MT/s by default. Four 288-pin slots accept up to 256 GB in dual-channel mode; non-ECC modules are required.

Can I run a PCIe 5.0 graphics card and two PCIe 5.0 M.2 drives simultaneously?

Yes. The CPU provides one PCIe 5.0 x16 slot and two M.2 sockets that each support PCIe 5.0 x4, so a Gen 5 GPU and two Gen 5 SSDs all run at full speed.

What cooling solution do I need for the included Ryzen 9 9900X?

The processor does not ship with a cooler. You will need an AM5-compatible air or liquid cooler rated for a 12-core, 24-thread CPU with a 5.6 GHz maximum boost clock.
