Dell PowerEdge T440 memory upgrade

This 8 GB DDR4 registered DIMM is built for the Dell PowerEdge T440 tower server. It targets administrators who need to expand system memory with a validated module that matches the platform's ECC and registered requirements.

Registered ECC design with 288-pin layout

The module uses a registered architecture and on-die error correction to maintain data integrity under sustained workloads. Its standard 288-pin form factor fits directly into the server's DDR4 slots without adapters or special tools.

2666 MT/s speed at CL19 latency

Rated at DDR4 2666 (PC4-21300) with a CAS latency of 19, this stick delivers the exact timing the T440 memory controller expects. Systems requiring a different speed grade or unbuffered modules will not be compatible.

Questions about this item

What DDR4 standard and speed does the PC4-21300 rating cap the module at?

The PC4-21300 rating corresponds to DDR4-2666, so the module runs at 2666 MT/s with a CL19 latency.

What physical slot and form factor does the 288-pin RDIMM require?

It fits a standard 288-pin DDR4 RDIMM slot; the module is unbuffered in height with no heat spreader.

How is the module installed and what step is often missed?

Power down the T440, open the chassis, align the notch on the 288-pin edge connector, press firmly until both retention clips click, then verify the new capacity in the BIOS.
