Overview
The ASRock X470 Master SLI/AC is a full-size ATX motherboard built on the AMD X470 (Promontory) chipset, designed for AMD AM4 socket Ryzen series processors including Summit Ridge, Raven Ridge, and Pinnacle Ridge generations. Measuring 12.0 in x 9.6 in (30.5 cm x 24.4 cm), it fits standard ATX enclosures and delivers a feature set oriented toward enthusiast builders who want multi-GPU capability, fast wireless connectivity, and robust storage options. For graphics, the board supports two PCI Express 3.0 x16 slots — running at x16 single or x8/x8 in dual configuration with Summit Ridge and Pinnacle Ridge CPUs — and is certified for both NVIDIA SLI and AMD CrossFireX. Four PCI Express 2.0 x1 slots round out the expansion bay. Storage options include six SATA3 6.0 Gb/s connectors with RAID 0, 1, and 10 support, one Ultra M.2 slot (M2_1) capable of PCIe Gen3 x4 at up to 32 Gb/s and SATA3 for drives up to Type 22110, and a second M.2 slot (M2_2) supporting PCIe Gen2 x2 at up to 10 Gb/s and SATA3 for drives up to Type 2280. The primary M.2 slot is covered by a full-coverage heatsink to help maintain sustained SSD performance. Memory support spans four DDR4 DIMM slots in dual-channel configuration, accepting up to 64 GB of unbuffered DDR4 at speeds from 2133 MHz up to 3466 MHz (OC). ECC memory is supported with compatible Pinnacle Ridge and Summit Ridge CPUs. Connectivity is extensive: the rear I/O provides one USB 3.1 Gen2 Type-A port and one USB 3.1 Gen2 Type-C port (both rated at 10 Gb/s), six USB 3.1 Gen1 ports, one HDMI port (4K at 30 Hz via compatible APU), one optical S/PDIF output, and a PS/2 combo port. Onboard headers add four USB 2.0 and four USB 3.1 Gen1 ports. Networking includes an Intel I211AT Gigabit LAN controller and an Intel 802.11ac dual-band (2.4/5 GHz) WiFi module with Bluetooth 4.2, plus two external antenna ports on the rear I/O. Audio is handled by a Realtek ALC892 codec delivering 7.1-channel HD audio with content protection, backed by Nichicon Fine Gold Series audio capacitors. The PCB itself uses ASRock's Super Alloy build quality: a 2 oz copper PCB, High Density Glass Fabric construction, XXL aluminium alloy heatsinks on the MOSFETs, Premium 45A power chokes, Nichicon 12K Black Caps (rated for at least 12,000 hours), and Full Spike Protection covering USB, audio, and LAN ports. RGB lighting is managed via ASRock Polychrome RGB software, with one standard RGB header (12V, up to 3A/36W) and one addressable RGB header (5V, up to 3A/15W). The board carries a 3-year warranty and FCC/CE certifications.
