Dell PowerEdge T440 memory upgrade

This 32 GB DDR4 ECC registered DIMM is built for the Dell PowerEdge T440 tower server. It delivers error-correcting stability for workloads that cannot tolerate data corruption. System administrators and IT teams use it to expand memory capacity in supported Dell enterprise platforms.

Single 32 GB module with CL19 timing

The kit contains one 288-pin RDIMM rated at 2666 MHz (PC4-21300) with 2Rx4 organisation and 1.20 V operation. CAS latency is CL19. No heat spreader is fitted, so airflow in the server chassis handles cooling. The module uses major OEM chips from Samsung, Micron or Hynix.

Verify Dell T440 slot population rules

Confirm the server has a free 288-pin DDR4 RDIMM slot and that the memory population order in the Dell service manual allows a 32 GB 2Rx4 registered module. Systems requiring unbuffered UDIMMs or non-ECC memory cannot use this part.

Questions about this item

Will the 32GB DDR4 2666 RDIMM need replacement for wear?

The module is solid-state with no moving parts and operates at 1.20V; it does not require scheduled replacement.

What limit appears first when the 2Rx4 ECC RDIMM runs at full 2666 speed continuously?

The CL19 latency and registered buffer set the timing ceiling; the memory controller throttles before the chips exceed their rated voltage.

How much heat and power does the 288-pin 32GB stick produce under all-day load?

At 1.2V the DRAM draws low power and has no heat spreader, so case airflow handles the thermal load without extra cooling.
