Memory & Platform
The Athlon PRO 300U fits into the FP5 socket and supports PCIe 3.0 with 8 total PCIe lanes for expansion cards and storage. It supports DDR4 Dual-channel memory at speeds up to DDR4-2400 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 32 GB across 2 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers. Integrated graphics: AMD Radeon Vega 3 — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.
