Socket AM4 platform board

The ASRock X470 Master SLI is an ATX motherboard built around the AMD X470 chipset for Socket AM4 processors. It targets builders who want a full-size board with multi-GPU flexibility and plenty of internal expansion. The board delivers a standard ATX layout with dual-channel DDR4 memory support across four DIMM slots.

Dual-channel DDR4 with four DIMM slots

The board provides four DDR4 DIMM slots running in dual-channel mode, supporting speeds from 2133 up to 3466 MHz. Two M.2 slots are available for expansion cards, while six SATA III ports handle storage drives. Front-panel connectivity includes two USB 2.0 and two USB 3.0 headers, plus an HD audio connector. Power delivery uses a 24-pin ATX connector and an 8-pin EPS connector, with three chassis-fan headers and a dedicated CPU-fan header for cooling.

64 GB maximum memory capacity

Maximum supported memory is 64 GB using unbuffered DDR4 modules, with ECC and non-ECC both accepted. The X470 chipset enables CrossFireX, Quad-GPU CrossFireX, SLI and Quad-GPU SLI configurations for multi-graphics setups. On-board audio outputs 7.1 channels. The board includes an EATX power connector alongside the standard ATX and EPS inputs, and carries FCC, CE and ErP certifications.
