PHS-memory 48GB DDR5 ECC SO-DIMM 5600MHz PC5-44800E ASRock IMB-A1003 SP587833

When a Mini-ITX board like the ASRock IMB-A1003 demands both compactness and data integrity, this 48GB DDR5 ECC SO-DIMM answers with a rare combination: error-correcting reliability in a small-outline module. Most SO-DIMMs skip ECC, but here you get server-grade protection for edge computing, embedded systems, or always-on workstations where a single-bit flip could corrupt critical results.

Highlights

• 48GB capacity – twice the typical 24GB SO-DIMM, ideal for memory-hungry virtual machines or large datasets.
• DDR5-5600 (PC5-44800E) – next-gen bandwidth up to 44.8 GB/s, keeping pace with modern CPUs.
• ECC error correction – detects and corrects single-bit errors, essential for 24/7 operation.
• 262-pin SO-DIMM form factor – fits Mini-ITX boards, laptops, and small form factor PCs.
• Unbuffered, dual-rank design – balances capacity and signal integrity for stable performance.
• Low 1.1V operating voltage – reduces power draw and heat in confined chassis.
• Plug-and-play compatibility with ASRock Mini-ITX IMB-A1003 – no BIOS tweaks required.

In daily use

Install this module into the IMB-A1003's SO-DIMM slot and the system immediately recognizes the full 48GB. For developers running containers, engineers processing sensor data, or IT admins managing edge nodes, the extra headroom means fewer swaps to disk and smoother multitasking. ECC works silently in the background, logging corrected errors and preventing crashes that non-ECC memory would allow.
