Overview

The Dell A6996789 (SNPMGY5TC/16G) is a 16GB DDR3 registered ECC memory module designed for Dell PowerEdge servers and compatible workstations. Operating at DDR3-1333 (PC3-10600) speeds with a low-voltage 1.35V specification, it delivers a balance of capacity and energy efficiency for servers still running on the DDR3 platform. The ECC registered architecture provides single-bit error correction and the buffered signal integrity needed for systems with high memory density, making it suitable for database servers, virtualization hosts, and other workloads where memory reliability is non-negotiable.

As a Dell-certified replacement part, the A6996789 is tested and validated for compatibility with specific Dell server models, eliminating the guesswork associated with third-party memory. Each 16GB module uses a 240-pin DIMM form factor and can be installed alongside existing memory to expand total system capacity. While DDR3 is now a legacy technology superseded by DDR4 and DDR5, this module remains a practical and economical option for organizations maintaining existing DDR3 server infrastructure that does not yet warrant a full platform upgrade.

Pros & Cons

👍 Pros

  • ECC Registered design provides error correction and stability essential for server uptime
  • 1.35V low-voltage operation reduces power consumption and heat in dense server configurations
  • Dell-certified (SNPMGY5TC/16G) ensures tested compatibility with supported PowerEdge servers
  • 16GB capacity per DIMM allows significant memory expansion without occupying additional slots
  • 240-pin DDR3 form factor fits a wide range of existing DDR3-era server platforms

👎 Cons

  • DDR3-1333 speed is significantly slower than current DDR4 and DDR5 server memory
  • Only compatible with servers that support registered ECC DIMMs, not usable in desktops or non-ECC systems
  • 16GB per module may require multiple sticks for meaningful capacity upgrades in memory-intensive workloads
  • Limited to Dell-compatible server platforms, narrowing its use compared to generic server RAM
  • Older generation technology that will not work in newer servers requiring DDR4 or DDR5

Frequently Asked Questions

This is a Dell-certified RDIMM (SNPMGY5TC/16G) designed for Dell PowerEdge servers that support DDR3-1333 registered ECC memory. Check your server's documentation to confirm compatibility with 16GB RDIMMs.
ECC (Error-Correcting Code) detects and corrects single-bit memory errors, while the Registered (buffered) design reduces electrical load on the memory controller, allowing servers to support higher total memory capacities with greater stability.
No. This is a 240-pin DDR3 RDIMM with ECC, which requires a server or workstation motherboard with a memory controller that supports registered ECC DIMMs. Standard desktops do not support this type of memory.
It operates at 1.35V, which is the low-voltage DDR3L standard. This reduces power consumption and heat output compared to standard 1.5V DDR3 modules.
