X470 Master SLI/AC AM4 Platform

The ASRock X470 Master SLI/AC is an ATX motherboard built around the AMD Promontory X470 chipset for the AM4 socket. It accepts Ryzen processors from the Matisse, Picasso, Summit Ridge, Raven Ridge and Pinnacle Ridge families. The board targets enthusiasts who need multi-GPU support and integrated wireless connectivity in a single package.

PCIe 3.0 x16 and 2.0 x1 Limits

Primary graphics run at PCIe 3.0 x16 from the CPU; a second card drops both slots to x8 and x8. Four PCIe 2.0 x1 slots handle add-in cards such as sound or capture devices. The Ultra M.2 socket (M2_1) delivers up to PCIe Gen3 x4 (32Gb/s) with Matisse, Picasso, Summit Ridge, Raven Ridge and Pinnacle Ridge CPUs, while a second M.2 socket (Key E) carries the bundled Wi-Fi 802.11 ac module.

64GB DDR4 Dual-Channel Ceiling

Four 288-pin DDR4 slots support a maximum of 64GB in dual-channel mode. Matisse CPUs officially run 3200/2933/2667/2400/2133 ECC and non-ECC; Pinnacle Ridge and Summit Ridge add 3466+(OC) and 3200(OC). Exceeding 64GB is not possible on this platform, so memory capacity is the decisive specification for builders planning large workloads.

Highlights

Questions about this item

Which memory speed should I pick for a Ryzen 3000 Matisse CPU on this board?

The specifications list DDR4 3200, 2933, 2667, 2400 and 2133 as supported speeds for Matisse processors, all running in dual-channel mode up to 64 GB total.

What resolution can the HDMI 1.4 port actually deliver when using a Ryzen APU?

The HDMI 1.4 output is rated for a maximum of 4K x 2K at 40 Hz, so 4K at 60 Hz is not available through this port.

What bandwidth does the Ultra M.2 slot provide with a Matisse CPU installed?

With a Matisse processor the Ultra M.2 socket runs at PCIe Gen3 x4, giving up to 32 Gb/s for a compatible M.2 drive.
