QCT Server Memory: QuantaGrid, QuantaPlex & QuantaEdge

Memory upgrades matched to your QCT (Quanta Cloud Technology) server. Each listing covers one QCT model and one memory type, with the speed, module sizes and kit sizes that model supports. To find yours, type the model into the search bar at the top of the page, for example D52B-1U, D53X-1U, D54Q-2U, D55X-1U, T42S-2U or EGX66Y-2U. The model name is on the system label. NEMIX offers QCT memory as DDR5 and DDR4 ECC Registered (RDIMM) and DDR4 Load Reduced (LRDIMM) modules. For help identifying your server and choosing memory, see the QCT server memory guide.

• QuantaEdge edge servers: EGX74I, EGX77I, EGX77B (DDR5) and EGX66Y, EGX63IS (DDR4-3200).

Choose the right memory type

DDR5 QCT servers take DDR5 ECC RDIMM. DDR4 QCT servers take DDR4 ECC RDIMM or, on models that list them, LRDIMM for the highest capacities. Do not mix RDIMM and LRDIMM in the same server, and install identical modules in each memory channel. Each listing names the slot count and the sizes NEMIX offers for that model.
