About the T440

The Dell PowerEdge T440 is an enterprise tower server engineered for computing and virtualization workloads. Powered by 2 Intel Xeon Scalable 1st Gen and 2nd Gen (up to 24 cores, 150W TDP) across 16 memory slots supporting up to 1024GB DDR4-2666 / DDR4-2933 RDIMM, the T440 balances throughput and memory capacity. In Dell's server catalog, the T440 succeeded the POWEREDGE-T430 and was followed by the POWEREDGE-T550, positioned alongside rival systems including PROLIANT-ML110-GEN10, THINKSYSTEM-ST550.

Options and compatibility

Processor support on the T440 utilizes 2 LGA3647 (Socket P0) sockets with thermal heatsinks matching CPU power envelopes. System memory slots on the T440 require DDR4-2666 / DDR4-2933 RDIMM modules, and mixing RDIMM with LRDIMM memory is not supported. The T440 tower chassis accepts X7K8W (3.5-inch LFF) drive carriers depending on backplane selection. Networking on the T440 uses Network Daughter Card (NDC), and expansion cards install into Up to 5 PCIe Gen3 slots risers.

How to identify it

Physical identification of the T440 is verified by the 14th-generation silver-gray brushed aluminum honeycomb bezel with the T440 badge on the front chassis ear. The pull-out information tag on the T440 control panel displays the 7-character Dell Service Tag and default login credentials. In iDRAC9, the server identifies as T440 with active firmware, slot mapping, and power telemetry.

Buying used

When evaluating a pre-owned T440, inspect the LGA3647 (Socket P0) CPU socket pins for damage and ensure retention clips are intact. Run Dell ePSA diagnostics across all 16 memory slots of the T440 to verify zero uncorrectable ECC faults under load. Verify that redundant power supplies in the T440 match in wattage and that iDRAC9 Enterprise remote console is enabled. Ensure required T440 drive caddies and bracket accessories are present.

Match the speed: 16Gb and 32Gb FC HBAs, switches and array ports work together, and each generation also runs one or two speeds below its own (a 32Gb port runs at 16Gb and 8Gb).
