Dell PowerEdge T440 server memory upgrade

This 64 GB DDR4 2666 LRDIMM module is built for the Dell PowerEdge T440 tower server. It targets IT teams that need to expand memory capacity in a single slot while keeping ECC protection and load-reduced signalling.

Replacing smaller RDIMMs or filling empty slots

The jump is worth it when workloads demand more capacity per channel than standard registered DIMMs can provide. A 4Rx4 load-reduced design lets the memory controller drive higher densities without exceeding electrical limits.

Check your T440 memory configuration first

Verify the system BIOS revision supports 64 GB LRDIMMs and confirm the maximum modules per channel for your CPU. Ensure no mixing rules block combining this module with existing RDIMMs in the same channel.

Questions about this item

Will the 288-pin LRDIMM fit the Dell PowerEdge T440 memory slots?

Yes, the 288-pin DDR4 LRDIMM form factor matches the T440 DIMM slots exactly.

What BIOS setting or population rule is commonly missed when installing this 4Rx4 module?

The T440 requires specific slot population order for LRDIMM ranks; follow the service manual sequence and verify the BIOS sees 64 GB per module after POST.

How do I know when the ECC LRDIMM needs replacement?

Monitor system logs for rising correctable error counts; persistent uncorrectable ECC events or repeated memory test failures indicate the module should be swapped.
