Compact AM5 Combo for High-End Gaming

This bundle pairs the ROG STRIX X870-I GAMING WIFI motherboard with the AMD Ryzen 7 9800X3D processor. The Mini-ITX board uses the X870 chipset and AM5 socket, supporting Ryzen 7000, 8000 and 9000 series CPUs. It targets builders who want flagship gaming performance in a small-form-factor chassis.

DDR5 Speeds Top Out at Platform Limits

Four 288-pin slots accept up to 96GB of DDR5 memory running at 4400 MT/s standard. With Ryzen 9000 series processors the board can reach 8400+ MT/s when overclocked, 8600+ MT/s with Ryzen 8000 series and 8000+ MT/s with Ryzen 7000 series. One PCIe 5.0 x16 slot and one PCIe 5.0 M.2 2280 slot connect directly to the CPU, while a second M.2 slot runs at PCIe 4.0 speeds from the chipset.

10+2+1 Power Stages and ProCool II Connectors

The VRM uses ten 110A power stages plus two and one auxiliary stages, fed by an 8-pin and 24-pin ProCool II power arrangement. Massive heatsinks with an integrated I/O cover and an L-shaped backplate cool the VRM and M.2 slots. Rear I/O includes WiFi 7 (802.11be) with 320MHz channels for up to 6.5Gbps throughput, 2.5Gbps LAN, USB4 and multiple USB 10Gbps and 5Gbps ports.

Questions about this item

Which CPU is included in this combo and what makes it different from other Ryzen 7 chips?

The bundle ships with the Ryzen 7 9800X3D, an AM5 desktop processor recognised with a CES 2025 Innovation Award for its gaming-focused design.

What memory speed will I actually see once the 9800X3D is installed and XMP is enabled?

With a Ryzen 9000 series CPU the board validates DDR5 up to 8400 MT/s overclocked, so the 9800X3D can run kits rated at that frequency when AEMP or manual OC is applied.

How fast is the onboard Wi-Fi 7 link in real-world use?

The 2x2 Wi-Fi 7 radio supports 320 MHz channels on the 6 GHz band and is rated for up to 6.5 Gbps maximum transfer rate under ideal conditions.
