Combo contents
This bundle pairs an ASUS ROG Strix B850-G Gaming WiFi S motherboard with an AMD Ryzen 9 9950X3D processor. The board uses the AMD B850 chipset and an AM5 socket. The CPU is a 16-core Granite Ridge part built on TSMC 4nm FinFET with a 170W TDP and 128MB of L3 cache. It targets enthusiasts who want a ready-matched platform for high-end gaming and heavy multitasking.
DDR5 memory limits
Four DIMM slots accept DDR5 modules up to a total capacity of 256GB. The platform supports Ryzen 7000, 8000 and 9000 series desktop processors. A single PCIe 5.0 x16 slot provides the primary expansion path for a graphics card. WIFI 7 and a USB 20Gbps Type-C port handle high-speed wireless and wired connectivity. Four M.2 sockets are available for fast storage.
Installation notes
The AM5 socket uses a land-grid array CPU with no pins on the package, so careful alignment and even pressure are essential when seating the 9950X3D. Applying a quality thermal interface to the 170W chip and securing the cooler with the correct mounting pressure prevents hotspots. Ensure the EPS power connectors are fully seated and update the BIOS to the latest revision for full Ryzen 9000 series support before first boot.
