DELL A7515505 16GB DDR3 1600 ECC Registered Server RAM

SKU CH-3FZT-1W6B4 MPN A7515505

A 16 GB DDR3-1600 ECC registered DIMM for compatible Dell PowerEdge servers

  • Total capacity16 GB
  • Rated speedDDR3 1600 (PC3 12800)
  • CAS latencyCL11
  • Rated voltage1.35 V
  • Buffer typeRegistered
  • Memory rank2Rx4
  • ECC protection prevents data corruption in critical workloads
  • Registered signal processing improves stability on heavily populated motherboards
  • 16 GB capacity extends virtual-machine density on supported Dell PowerEdge servers
  • DDR3-1600 speed matches PC3-12800 platform requirements
  • Low 1.35 V operation reduces power draw per module

Target Platform

This 16 GB DDR3 module is built for Dell PowerEdge servers and Precision workstations that require registered ECC memory. It suits administrators upgrading compatible C-series, M-series, R-series or T-series systems where the platform specifies PC3-12800 registered DIMMs.

Registered ECC

The module operates as 2Rx4 registered ECC at CL11 with a 1.35 V supply. The registered buffer and error-correcting code are mandatory for the supported PowerEdge platforms; unbuffered or non-ECC DIMMs will not function in those slots.

Sustained Operation

Registered ECC construction and the low-voltage DDR3 design maintain data integrity and consistent timing during continuous server workloads. The buffer reduces electrical load on the memory controller, allowing stable throughput across all populated channels over long periods.

Questions about this item

What does the 1600 MHz speed mean when this module is installed in a server?

The module runs at 1600 MHz, delivering PC3-12800 bandwidth with CL11 latency; actual throughput depends on the server's memory controller and how many DIMMs populate each channel.

How does the DDR3 240-pin registered ECC interface limit usable capacity per channel?

Registered ECC adds a clock cycle for address buffering, so the memory controller must support registered DIMMs; maximum capacity per channel is set by the server's chipset and BIOS, not by the module alone.

Will this 240-pin DIMM fit in a PowerEdge R720?

Yes — the 240-pin DDR3 form factor matches the R720's DIMM slots, and the module is listed as compatible with that model.
