About the R740

The Dell PowerEdge R740 is an enterprise 2U rack server engineered for computing and virtualization workloads. Powered by 2 Intel Xeon Scalable 1st Gen (Skylake) and 2nd Gen (Cascade Lake) across 24 memory slots supporting up to 3072GB DDR4-2666 / DDR4-2933 RDIMM / LRDIMM, the R740 balances throughput and memory capacity. In Dell's server catalog, the R740 succeeded the POWEREDGE-R730 and was followed by the POWEREDGE-R750, positioned alongside rival systems including PROLIANT-DL380-GEN10, THINKSYSTEM-SR650.

Options and compatibility

Processor support on the R740 utilizes 2 LGA3647 (Socket P0) sockets with thermal heatsinks matching CPU power envelopes. System memory slots on the R740 require DDR4-2666 / DDR4-2933 RDIMM / LRDIMM modules, and mixing RDIMM with LRDIMM memory is not supported. Front backplanes on the R740 accommodate either DXD9H (2.5-inch SFF) or X7K8W (3.5-inch LFF) trays based on chassis option. Networking on the R740 uses Network Daughter Card (NDC), and expansion cards install into Up to 8 PCIe Gen3 slots risers.

How to identify it

Physical identification of the R740 is verified by the 14th-generation silver-gray brushed aluminum honeycomb bezel with the R740 badge on the front chassis ear. The pull-out information tag on the R740 control panel displays the 7-character Dell Service Tag and default login credentials. In iDRAC9, the server identifies as R740 with active firmware, slot mapping, and power telemetry.

Buying used

When evaluating a pre-owned R740, inspect the LGA3647 (Socket P0) CPU socket pins for damage and ensure retention clips are intact. Run Dell ePSA diagnostics across all 24 memory slots of the R740 to verify zero uncorrectable ECC faults under load. Verify that redundant power supplies in the R740 match in wattage and that iDRAC9 Enterprise remote console is enabled. Ensure required R740 drive caddies and bracket accessories are present.

Works together

How the Dell PowerEdge R740 connects to servers, storage and the network: 4 ways, with the parts and products on each path.

Fibre Channel SAN

Serverwith an FC HBAFC switchtwo fabrics, A and BStorage arrayFC host ports

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).
