Socket AM4 DDR4 motherboard

The ASUS B350M-DRAGON is a Micro ATX board built around the AMD B350 chipset for Socket AM4 processors. It targets builders who want a compact foundation for Ryzen or 7th generation A-series and Athlon CPUs without paying for full-size ATX features. The board measures 22.6 by 22.1 centimetres and fits standard Micro ATX chassis.

32GB dual-channel memory limit

Four DDR4 slots support up to 32GB total in dual-channel mode with rated speeds of 3200, 2933, 2666, 2400 and 2133MHz, all listed as overclocking steps above the base JEDEC speeds. Populating all four slots at the highest frequencies may require manual tuning and can hit stability walls sooner than two-slot configurations. The 32GB ceiling suits mainstream gaming and productivity but rules out heavy virtualisation or large content-creation datasets.

Expansion layout and I/O basics

A single PCI Express 3.0 x16 slot and one PCI Express 2.0 x1 slot provide room for a graphics card and one add-in board such as a capture card or extra USB controller. Storage connects through four SATA III ports and two M.2 interfaces that share bandwidth with the chipset. Networking uses a Realtek RTL8111H Gigabit LAN controller and audio runs on a Realtek ALC887 codec. The retail package includes the board, an I/O shield and one SATA cable.

Questions about this item

Will my existing Ryzen processor fit the AM4 socket on this B350 board?

Yes, the board uses the AM4 socket which is designed for Ryzen and 7th generation A-series or Athlon processors with AM4 slots.

How can I verify the Realtek ALC887 audio and RTL8111H LAN are working after I build the system?

Check Device Manager in Windows or run lspci on Linux; both chips should appear without error codes and audio playback plus a wired network link should function immediately.

What accessories come in the box and what must I source myself?

The package includes the motherboard, one SATA cable and the chassis I/O back panel; you will need to buy DDR4 memory, a CPU cooler, storage drives and a power supply separately.
