2.5G Network Solution

The premium 2.5G LAN on this board delivers a better network experience than standard Gigabit Ethernet, which matters for large game downloads, network storage and smooth online play on a wired connection. Turbo M.2 delivers speeds up to 32Gb/s from the Gen3 x4 M.2 slot, while Core Boost and DDR4 Boost support multi-core processors and clean memory signalling. Heavy plated heatsinks round out a design aimed at dependable daily use.

1. Reuse an older Ryzen processor or drop in a Ryzen 5000 Series chip to extend the life of an existing AM4 system.
2. Install up to 64GB of DDR4 in dual-channel mode across the two slots.
3. Combine a PCIe 3.0 x4 NVMe SSD with SATA drives, and use the 2.5Gbps LAN for fast wired networking.
