AM5 X870 Motherboard with Ryzen 7 9800X3D

This bundle pairs an MSI X870 GAMING PLUS WIFI board with an AMD Ryzen 7 9800X3D processor on the AM5 socket. The board uses the X870 chipset and a 14+2+1 Duet Rail power system with dual 8-pin CPU connectors. It supports Ryzen 9000, 8000 and 7000 series CPUs and up to 256GB of DDR5 across four 288-pin slots.

Gamers wanting 3D V-Cache and PCIe 5.0 M.2

The Ryzen 7 9800X3D targets players who benefit from extra L3 cache in latency-sensitive titles. Builders needing PCIe 5.0 x16 graphics and a PCIe 5.0 M.2 slot from the CPU will use the primary lanes. Users limited to PCIe 4.0 CPUs such as the 8700 or 8600 series lose the 5.0 x16 link and should consider a different platform.

Sustained load on 60A VRM and Frozr Guard

The 60A SPS VRM stages feed the CPU through an 8-layer PCB with 2oz copper. MOSFET thermal pads rated for 7W/mK and additional choke pads transfer heat to the extended heatsink. The EZ M.2 Shield Frozr II covers the primary M.2_1 slot, keeping a Gen5 drive at stable temperatures during long sessions.

Questions about this item

What DDR5 memory do I need to reach the 8200+ MT/s overclocked speed?

You need DDR5 modules rated for 8200 MT/s or higher. The board has four 288-pin slots supporting dual-channel up to 256 GB. With Ryzen 9000 series, 1DPC 1R configurations can hit 8200+ MT/s, 1DPC 2R up to 6400+ MT/s. JEDEC baseline is 4800-5600 MT/s.

Will my PCIe 4.0 graphics card work in the PCI_E1 slot that is wired for PCIe 5.0 x16?

Yes. The PCI_E1 slot runs at PCIe 5.0 x16 from the CPU but is backward compatible with PCIe 4.0 and 3.0 cards. The card will operate at its native generation and lane width.

How can I confirm the M.2_1 slot is running at PCIe 5.0 x4 after installing a drive?

Check the BIOS NVMe information page or use a Windows tool such as HWInfo. It will report the link width and generation for M.2_1, which is wired from the CPU for PCIe 5.0 x4 and accepts 2280 or 2260 form factors.
