AM4 platform for Ryzen builds

This extended ATX motherboard uses the AMD X370 chipset and AM4 socket to support Ryzen, Athlon and A-Series processors. Four DDR4 slots accept up to 64 GB of memory running at 2666 in dual-channel mode. Two M.2 sockets and eight SATA 6Gb/s ports provide flexible storage options for high-performance desktops.

5-Way Optimization and cooling headers

The on-board 5-Way Optimization suite includes Auto-Tuning and Fanpert 4 for automatic overclocking profiles and fan control. Dedicated AIO and water-cooling headers allow liquid-cooling loops to be managed directly from the board, helping keep temperatures and noise in check during everyday workloads.

Reinforced Safe Slots and sustained I/O

Two Safe Slots use an injection-moulded metal frame to anchor heavy graphics cards securely under long-term stress. The Intel i211AT Gigabit LAN controller, SupremeFX S1220 8-channel audio and dual M.2 drives maintain consistent throughput during extended sessions, while AURA Sync RGB headers enable lighting personalisation.

Questions about this item

How do I install the CPU on the AM4 socket and what step is often missed?

Align the triangle on the Ryzen processor with the socket corner, lower the retention arm fully until it clicks, then attach the cooler — many builders forget to remove the protective plastic cover on the socket before seating the CPU.

What maintenance will the ROG SupremeFX S1220 audio codec need over time?

The onboard audio codec itself requires no scheduled maintenance; keep the rear-panel jacks dust-free with compressed air and update the Realtek driver from ASUS support when a new version appears.

What limit appears first when running all eight SATA 6Gb/s ports under sustained heavy I/O?

The chipset-linked SATA controller shares bandwidth with the two M.2 slots and PCIe x1 lanes, so simultaneous maximum throughput on every SATA port will hit the X370 upstream PCIe 3.0 x4 bottleneck before any individual drive saturates.
