DELL A7515505 16GB DDR3 1600MHz ECC Registered DIMM server RAM

SKU CH-D6K4-6MTY6 MPN A7515505

16 GB DDR3 ECC registered DIMM running at 1600 MHz with 1.35 V low voltage for compatible Dell PowerEdge servers

  • ECC protection prevents data errors in critical workloads
  • 35 V low-voltage DDR3 reduces server power draw
  • Registered signal processing enables high-capacity memory configurations
  • 1600 MHz DDR3-1600/PC3-12800 speed matches platform requirements
  • Compatible with Dell PowerEdge servers including R610, R710, R720 and T620

Dell 16 GB DDR3-1600 ECC Registered DIMM

This 16 GB DDR3 module runs at 1600 MHz with a CAS latency of CL11 and operates at 1.35 V. It uses a 240-pin DIMM form factor and includes error-correcting code with registered signal processing for data integrity. The single-module design suits servers and workstations that require reliable memory subsystems.

Upgrade from smaller DDR3 ECC modules

Replacing lower-capacity DDR3 ECC registered DIMMs with this 16 GB unit increases total memory without adding slots. The jump is worthwhile when workloads exceed the current memory ceiling and the platform supports DDR3-1600/PC3-12800 registered modules. Systems limited to unbuffered memory or lower speeds cannot use this module.

Sustained load behaviour in compatible Dell

Under continuous operation the registered buffer reduces electrical load on the memory controller, helping maintain stability during extended compute tasks. ECC detects and corrects single-bit errors that can accumulate over long runtimes. The 1.35 V rating lowers power draw compared to standard-voltage DDR3, contributing to steadier thermal characteristics in dense configurations.

Questions about this item

Will the 240-pin DIMM fit my server's memory slots?

This module uses the standard 240-pin DDR3 DIMM form factor. It fits any server board that accepts DDR3 registered ECC DIMMs at 1.35 V.

What is the correct way to seat the module, and what step do people often miss?

Align the notch with the slot key, press down firmly until both side clips click shut. The step often missed is verifying both clips engage fully.

When will this 16GB DDR3 ECC registered DIMM need replacement?

Replace it if memory diagnostics report uncorrectable ECC errors, if the system fails to POST with the module installed, or during a planned platform upgrade.
