Dell PowerEdge R240 — supported memory

Which DDR4 UDIMM modules fit the PowerEdge R240, and the compatible parts we track.

Memory support vendor documentation
GenerationDDR4
Form factorsUDIMM
Max speedup to 2666 MT/s CPU-dependent
4 DDR4 DIMM slots (2 channels, up to 2 DIMMs per channel), ECC UDIMM only (technical guide: '8GB/16GB 2666MT/s Unbuffered with ECC only'). Up to 2666 MT/s; supported-DIMM offering list also includes 2666/2400/2133-rated ECC UDIMMs. Up to 16 GB per DIMM / 64 GB total. CPUs: Intel Xeon E-2200 family, Pentium, Core i3, Celeron (1-socket 1U). Spec sheet's 'Supports registered ECC' phrasing is a known wording slip; the technical guide states unbuffered ECC UDIMM only, no RDIMM/LRDIMM.

Confirmed = listed in the vendor's memory documentation for this server. Vendor match = the vendor's own part cross-reference matches the module and its speed is validated for the platform; not taken from this server's memory list. Spec match = meets this platform's JEDEC requirements (generation, form factor, validated speed); interchangeability is spec-based, not per-server testing. How we verify →
