Dell AB663418 16GB DDR4 ECC UDIMM Server Memory Module
Overview
The Dell AB663418 is a 16GB DDR4 ECC Unbuffered UDIMM memory module designed for Dell servers and workstation-class systems that require ECC-based data integrity in a non-registered memory format.
It operates at DDR4-3200 MT/s (PC4-25600) and uses a 288-pin UDIMM form factor, making it suitable for entry-level servers and ECC-supported workstation platforms. The module is typically single-rank (1Rx8) with ECC error correction for improved system stability in business-critical workloads.
Unlike RDIMM server memory, this UDIMM variant is intended for systems that support ECC UDIMM configurations (not fully buffered server RDIMMs), making it common in lower-tier PowerEdge servers and workstation-class Dell systems.
Deployment is limited to compatible Dell platforms that explicitly support ECC UDIMM DDR4 memory at 3200 MT/s. It is not compatible with laptops, non-ECC desktops, or RDIMM-only server architectures.
