Dell 16GB DDR4 2666 RDIMM

This 16GB registered DIMM targets Dell desktop and workstation owners who need validated ECC memory. It runs at 2666 MT/s with a CL1.5 latency profile. The module is qualified by Dell for specific systems to reduce compatibility risk.

Fits Dell platforms using DDR4 RDIMM slots

Installation requires an available RDIMM slot on a compatible Dell motherboard. The registered design adds a buffer that reduces electrical load on the memory controller. Mixing with other speeds forces operation at the lowest populated frequency or the system maximum.

16GB capacity for multi-tasking headroom

The single module provides 16GB of addressable memory for typical productivity workloads. Capacity limits appear when running large virtual machines, heavy rendering queues or memory-intensive databases. Additional modules can be added if the platform supports higher total memory.

Questions about this item

Will the CL1.5 latency limit responsiveness when the module runs at 2666 MT/s for long periods?

The module is rated CL1.5 at 2666 MT/s, so latency stays at that specification during sustained operation.

Does the RDIMM design change heat output or power draw when the memory runs all day?

Registered DIMMs add a small buffer that slightly increases power use, but the module has no LED or extra circuitry that would raise heat noticeably.

Which Dell desktop must I already own for this SNPPWR5TC16G module to work?

It is qualified for select Dell systems listed under part number AA940922; check your service tag against that list before purchasing.
