Memory & Platform

The Atom E3827 fits into the FCBGA1170 socket and supports PCIe 2.0 with 4 total PCIe lanes for expansion cards and storage. It supports DDR3 memory at speeds up to DDR3L-1333 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 8 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: Intel HD Graphics (Bay Trail) — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.
