AM4 Ryzen platform

The ASRock B550M PRO4 is a micro-ATX motherboard built around the AMD B550 chipset for socket AM4 processors. It supports Ryzen 5000, 5000 G-Series, 4000 G-Series, 3000 and 3000 G-Series CPUs, though a BIOS update may be required for Zen 3 parts. The board is not compatible with Athlon processors.

8-phase Digi Power

An 8-phase Digi Power design delivers smooth current to the CPU and keeps VRM temperatures low during typical workloads. Passive heatsinks on the power stages dissipate heat without adding fan noise. The board draws only the power required by the installed components.

DDR4 4733 OC ceiling

Four 288-pin slots accept unbuffered DDR4 up to 128 GB in dual-channel mode. Supported speeds range from 2133 to 4733+(OC) with Ryzen 5000 G-Series APUs and 4533+(OC) with Ryzen 5000 CPUs. Intel XMP 2.0 profiles are recognised for simplified memory overclocking.
