Dell PowerEdge R240/R340 Memory Kit

This 32GB kit contains two 16GB DDR4 modules built for Dell PowerEdge R240 and R340 servers. The unregistered ECC DIMMs add error-correcting capacity to systems that support up to 64GB across four slots.

ECC Unregistered DDR4-2666 CL19

Each stick runs at DDR4 2666 (PC4-21300) with CL19 19-19-19 timing at 1.2V. The 2Rx8 organisation and 288-pin form factor match the platform's native memory controller requirements.

Sustained Server Workload Operation

Without heat spreaders the modules rely on chassis airflow, which the R240 and R340 provide in their intended rack positions. ECC correction operates continuously during long compute or virtualisation tasks, preventing silent data corruption that non-ECC memory cannot detect.

Questions about this item

What does the 2666 MHz speed actually deliver once the modules are installed in a PowerEdge R240?

The kit runs at DDR4 2666 (PC4 21300) with CL19 timing and 1.2 V; if the installed processor only supports a lower memory frequency the modules will automatically clock down to that optimal speed.

How does the ECC unregistered DDR4 interface limit the maximum usable capacity in these servers?

Each module is a 16 GB 2Rx8 ECC unregistered DIMM; the PowerEdge R240 and R340 each have four 288-pin slots and a 64 GB ceiling, so two modules give 32 GB and leave two slots free for future expansion.

What physical clearance is needed to seat these 288-pin DIMMs in the target servers?

The sticks are standard-height 288-pin DDR4 DIMMs without heat spreaders, so they fit the regular DIMM slots in the PowerEdge R240 and R340 without requiring low-profile clearance or extra airflow space.
