Dell PowerEdge R240 compatible memory

This 8 GB DDR4 ECC RDIMM is built for the Dell PowerEdge R240 rack server. It delivers registered error-correcting memory for workloads that require data integrity. The single-rank module installs in a standard 288-pin DDR4 slot.

Sustained load behaviour

Registered buffering and ECC protect data during continuous operation in multi-user or virtualised environments. The 1.2 V operating voltage keeps power draw predictable under long-running tasks. CL19 latency at 2666 MHz provides stable throughput for server applications.

Deciding specification

ECC registered RDIMM format is mandatory for the PowerEdge R240 memory controller. Non-ECC or unbuffered modules will not function in this system. Verify the server requires registered memory before ordering.

Questions about this item

Does the 1.20 V registered ECC module add noticeable heat or fan noise when the PowerEdge R240 runs continuously?

The 1.20 V DDR4 RDIMM operates at standard server voltage and, being a single-rank 1Rx8 module without a heat spreader, it stays within the thermal envelope Dell designed for the R240, so fan curves remain unchanged during all-day workloads.

What must the server already have for this 288-pin DDR4 RDIMM to function?

The R240 needs an available DDR4 RDIMM slot, a CPU and chipset that support ECC registered memory, and a BIOS version that recognises 2666 MHz PC4-21300 modules.

Can I keep my existing 2666 MHz ECC RDIMMs and add this 8 GB stick without changing BIOS settings?

Yes, matching speed, voltage, rank and registered ECC type lets the new 8 GB module join the current population; the system will train at the common 2666 MHz CL19 timings automatically.
