  • 10 V operation reduces power draw per module
  • Single-rank 1Rx8 layout fits dense memory configurations
  • Major-brand Samsung, Micron or Hynix chips ensure reliability

Dell PowerEdge R660xs Server Memory

This 16GB DDR5 RDIMM is built for the Dell PowerEdge R660xs rack server. IT teams upgrading memory in that platform will find a registered ECC module validated for the system. Buyers who need consumer desktop RAM or non-ECC modules should look elsewhere.

Sustained Workload Stability

Registered buffering and on-die ECC keep data integrity intact during continuous server tasks. The CL40 timing at 4800 MT/s delivers steady throughput for virtualization and database workloads. Modules without ECC or registered signalling cannot meet the same reliability requirements.

Thermals and Power in Rack Use

Operating at 1.10V, the module runs without a heat spreader in the chassis airflow. The low voltage helps contain power draw per DIMM slot in dense configurations. Buyers who need passive cooling in fanless enclosures will need a different solution.
