QNAP RAM-16GDR4-LD-2133 16GB DDR4 Long-DIMM Memory Module
Overview
The RAM-16GDR4-LD-2133 is a 16GB DDR4 Long-DIMM module running at 2133 MHz, designed for capacity expansion in compatible QNAP NAS systems. If you're running memory-intensive workloads — virtualization, concurrent surveillance stream indexing, or containerized applications via QTS — adding a genuine QNAP-spec module ensures the system's memory controller operates within validated parameters rather than relying on third-party compatibility guesses. The 288-pin Long-DIMM form factor is distinct from standard UDIMMs and SO-DIMMs; confirm your enclosure accepts Long-DIMM before ordering.
Compatibility
This module is designed for QNAP NAS enclosures that specify DDR4 Long-DIMM (LD-DIMM) support. Compatible families typically include higher-density rackmount and tower NAS units in the TVS, TS, and TES series that explicitly list Long-DIMM slots in their hardware specification. Because Long-DIMM is a load-reduced buffered format, it is not interchangeable with standard UDIMM or ECC UDIMM slots — verify your specific model's memory specification sheet before purchasing. For dual-channel performance, install matched pairs in the correct slot sequence as documented in your enclosure's quick installation guide.
Installation Notes
Power down the NAS completely and discharge static before handling. Long-DIMM modules require firm, even pressure to seat fully — partial insertion can cause boot failure or memory errors without obvious physical indication. After installation, QTS will report updated memory capacity under System > Hardware Information; if the module is not recognized, reseat before suspecting a compatibility issue. Do not mix DDR4 Long-DIMM with other DDR4 variants in the same system unless your model's specification explicitly supports mixed configurations.
