FAQ, PowerEdge R660

Four questions, four direct answers.

  • How much DDR5 memory does the Dell PowerEdge R660 support?

    Up to 8TB across 32 DIMM slots. Populate in matched kits per CPU socket. Mixing capacities or speeds will downclock every module to the slowest installed, so order one kit per socket and you keep full bandwidth and a clean memory test.

  • What DDR5 speeds does the PowerEdge R660 run at?

    4800 MT/s and 5600 MT/s. Modules rated higher than 5600 MT/s will downclock to 5600 MT/s. Modules slower than 4800 MT/s are not supported.

  • RDIMM or LRDIMM in the PowerEdge R660?

    Both. RDIMM is the default below 64GB per module; LRDIMM earns its keep above that, where the buffered electrical load lets you populate more high-capacity DIMMs at full speed. If you're maxing out capacity, ask for an LRDIMM-populated kit.

  • Where does VeriLicense source DDR5 for the PowerEdge R660?

    Authorised distribution. We carry several confirmed-compatible modules above in RDIMM and LRDIMM form, sealed and ECC-verified. Same-day quotes during UK office hours, same-day shipping on stocked SKUs.
