Dell PowerEdge T440 memory upgrade

This 16 GB DDR4 2666 ECC RDIMM is built for the Dell PowerEdge T440 tower server. It targets administrators who need registered, error-correcting memory to maintain data integrity in production workloads. The single-rank module uses major-brand DRAM chips and runs at 1.2 V.

Replacing slower or non-ECC DDR4

The module steps up from lower-speed DDR4 or unbuffered DIMMs that lack error correction. The jump is worth it when the server runs virtualisation, databases or long compute jobs that cannot tolerate silent data corruption. Registered signalling also allows larger total capacities per channel.

Fitting into a T440 build

The 288-pin RDIMM slots directly into the T440 memory sockets without adapters. ECC and registered operation free the memory controller from parity overhead, leaving more bandwidth for applications. No heat spreader is fitted, so airflow from the standard chassis fans is sufficient.

Questions about this item

Does the 288-pin DDR4 RDIMM fit the Dell PowerEdge T440 memory slots?

Yes, the 288-pin DDR4 RDIMM is the correct form factor for the Dell PowerEdge T440 server memory slots.

What is the correct order to install this 2Rx8 ECC RDIMM in the T440?

Follow the Dell PowerEdge T440 owner manual DIMM population sequence; the common mistake is skipping the required slot order for registered memory.

When should this 1.2V ECC module be replaced?

Replace the module if system diagnostics report correctable ECC errors that increase over time or if the server fails memory self-test at boot.
