Dell PowerEdge R740 — Full Technical Specifications
The R740 is the two-socket workhorse of Dell's fourteenth generation and, by volume, among the most widely deployed rack servers ever sold. That ubiquity is the argument for one: rails, caddies, spare parts and documented configurations are everywhere, and so is the engineer who has worked on one before.
We list it new, built to order, and refurbished — and refurbished is where most of the demand for this model now sits.

Full Specifications
Everything below describes a family rather than a unit, so the useful way through it is subtractive: start from the configuration you need and check that the row above permits it. Accelerator support and slot count are the pair that most often disqualifies a cheap listing found elsewhere — chassis, riser and supply all have to agree before a card will run, and a machine sold without them is not one you can upgrade into it. The memory row names both conventional and persistent options; only one of those survives a change of processor family, which is worth knowing before a used R740 is bought on the strength of that line.
