Socket AM4 ATX motherboard

The ASRock Fatal1ty X470 Gaming K4 is an ATX board built around the AMD Promontory X470 chipset and the AM4 socket. It accepts Ryzen 2000, 3000, 4000 G-Series, 5000 and 5000 G-Series desktop processors with a 12-phase Digi Power design. Four DDR4 DIMM slots support dual-channel memory up to 64 GB and speeds of 3466+ when overclocked.

Builders expanding an AM4 system

This board suits builders extending an existing AM4 platform who need multiple PCIe 3.0 x16 slots for multi-GPU configurations and a broad USB 3.1 Gen1 and Gen2 complement. It is not for buyers who require a newer socket generation, integrated Wi-Fi, or more than two M.2 sockets.

3466+ OC DDR4 ceiling

The maximum supported memory frequency of 3466+ (OC) with compatible Ryzen CPUs is the single spec that decides whether this board matches a high-frequency memory kit. If the planned kit is rated above that ceiling, the board cannot guarantee the advertised speed.
