  • HDMI and DisplayPort outputs for integrated graphics

Micro ATX AM4 platform for Ryzen builds

This micro ATX motherboard uses the AMD B550 chipset and an AM4 socket for Ryzen processors. It provides four DDR4 memory slots with a maximum capacity of 128 GB. Connectivity includes Gigabit Ethernet and IEEE 802.11ac wireless, plus HDMI and DisplayPort video outputs. The board suits compact systems that still need full memory expansion.

Builders who need four slots

The four DIMM slots and integrated Wi-Fi make this board a fit for small-form-factor PCs that require up to 128 GB of DDR4. Users who need more than two M.2 sockets, additional USB 3.0 headers or a larger ATX layout should consider other form factors. It also lacks built-in Bluetooth unless the wireless module provides it.

Maximum DDR4 capacity of 128 GB across four slots

The 128 GB ceiling is the decisive figure when planning memory-heavy workloads such as virtualisation or content creation. Populating all four slots lets you reach that limit with standard DDR4 modules. If your project demands more than 128 GB of system memory, this motherboard cannot meet the requirement.

Perguntas sobre este artigo

How do I install the CPU in the AM4 socket without bending pins?

Align the golden triangle on the Ryzen processor with the socket corner marker, lower it straight down without force, then lock the retention arm. The step people miss is checking that all pins sit flat before locking.

What maintenance will the DDR4 memory slots need over time?

Dust the four slots with compressed air once a year and reseat modules if the system fails to POST. No battery replacement is required for the memory controller itself.

At what DDR4 speed does the board hit its memory-controller limit with four dual-rank sticks populated?

With two DIMMs per channel and dual-rank modules the maximum supported JEDEC speed is 3466 MHz; faster XMP profiles will not be stable in that configuration.
