Combo contents

This bundle pairs an ASUS ROG STRIX X870E-H GAMING WIFI7 motherboard with an AMD Ryzen 9 9900X processor. The CPU delivers 12 cores and 24 threads on the Zen 5 architecture with a 5.6 GHz max boost. The board uses the AMD X870E chipset on an ATX form factor. Together they target builders who want a high-core-count platform for AI workloads, content creation and gaming.

Before ordering

Verify that your chassis accepts a 12.0" x 9.6" ATX board and has room for the integrated I/O cover heatsink. The power design requires two 8-pin +12V CPU connectors alongside the 24-pin main connector. Memory must be DDR5; the board runs up to 8000+ MT/s when overclocked and supports 256 GB across four 288-pin slots in dual-channel mode. A CPU cooler is not included.

What the bundle changes

The motherboard adds two PCIe 5.0 M.2 slots and two PCIe 4.0 M.2 slots, each with substantial cooling. Rear I/O includes two USB4 40 Gbps Type-C ports, four USB 10 Gbps ports and six USB 5 Gbps ports. Networking features WiFi 7 (802.11be) and Realtek 5 Gb Ethernet. Onboard headers provide one USB 20 Gbps Type-C connector, addressable RGB Gen 2 headers and multiple 4-pin fan headers including an AIO pump header.

Questions about this item

What comes in the box and do I need to buy a CPU cooler separately?

The combo includes the ROG STRIX X870E-H GAMING WIFI7 motherboard and the Ryzen 9 9900X processor. A CPU cooler is not included and must be purchased separately.

Which memory speed should I choose for the four DDR5 slots to reach the 8000+ MT/s OC figure?

The board supports up to 8000+ MT/s when overclocked with a Ryzen 9000 series CPU. Install a DDR5 kit rated for that speed or higher and enable the EXPO profile in the UEFI BIOS.

What does the 5.6 GHz max boost clock mean for everyday workloads on the 12-core 9900X?

The 5.6 GHz max boost is the highest single-core frequency the 12-core 9900X can reach under light loads. All-core speeds under sustained heavy workloads will be lower and depend on your cooling solution.
