ASRock X370 PRO4 AMD motherboard

Socket AM4 platform for Ryzen and A-Series

This ATX motherboard uses the AMD Promontory X370 chipset to support Socket AM4 processors from the Ryzen Summit Ridge and Raven Ridge families as well as 7th Generation A-Series APUs codenamed Bristol Ridge. It targets builders assembling a mid-range desktop around those specific CPU lines.

DDR4 memory speeds and SATA connectivity limits

Ryzen processors on this board can run DDR4 memory at 3200, 2933, 2667, 2400 or 2133 MT/s depending on the memory controller and overclocking headroom, while Bristol Ridge APUs are limited to 2400 and 2133 MT/s. Storage expansion relies on SATA 6 Gb/s ports and the board includes USB 3.1 for external devices.

Nine-phase power and crossfire support in an ATX

A nine-phase power design backs the stated 95 W air-cooling limit for the CPU socket, giving headroom for mainstream chips under sustained load. The full-size ATX form factor provides the physical slots required for AMD Quad CrossFireX and standard CrossFireX multi-GPU configurations, while HDMI output handles integrated graphics on compatible APUs.
