Dell PowerEdge 12th Gen DDR3 kit

This 24 GB kit contains three 8 GB registered ECC DDR3 modules built for Dell PowerEdge 12th generation rack servers. It targets administrators who need to expand memory capacity in R320 through R920 platforms without mixing unbuffered desktop memory.

24 GB capacity at 1600 MHz

The three dual-rank 2Rx4 modules deliver 24 GB total at PC3-12800 speed with CL11 latency. Registered buffering and ECC protect data integrity under sustained server workloads, while the 1.5 V operating voltage matches the platform specification. Systems requiring larger populations or higher densities will exceed this kit's module count and rank limits.

Thermals and power in server use

Bare modules without heat spreaders rely on the chassis airflow designed for Dell PowerEdge 12th gen racks. At 1.5 V the kit draws standard DDR3 registered DIMM power, and the registered buffers add minimal overhead. Acoustic output remains governed by the server fan curves rather than the memory itself.

Questions about this item

Will this 240-pin DDR3 1600 RDIMM work with the existing modules in my PowerEdge R720?

Yes, the kit is designed for Dell PowerEdge R720 and other 12th Gen rack servers; match speed, voltage and registered ECC type when mixing with installed DIMMs.

How can I verify the kit is running at DDR3 1600 CL11 after installation?

Check the BIOS memory information or use a tool such as dmidecode to confirm 1600 MT/s, CL11 timing, 1.5 V and registered ECC status.

Does the package contain three 8 GB modules or do I need to buy any separately?

The box includes three 8 GB modules for a total of 24 GB; no additional modules are required for this kit.
