Server-Ready DDR5 ECC Module

The Kingston KTD-PE548D4-64G is a 64GB DDR5-4800 registered DIMM built for enterprise servers and workstations that require error-correcting memory. Its 288-pin form factor and 1.10V operation match standard DDR5 server slots. The module targets IT departments and system integrators deploying high-density memory configurations.

Sustained Load Stability

Registered signal processing buffers address and command lines to reduce electrical load on the memory bus during continuous operation. The CL40 latency and 2Rx4 organisation support steady throughput for virtualisation, database and compute workloads. ECC circuitry detects and corrects single-bit errors without interrupting service.

DDR5 Platform Constraints

DDR5 architecture moves power management onto the module itself, so the 1.10V supply is regulated locally rather than by the motherboard. Maximum capacity and speed depend on the specific CPU memory controller and qualified vendor list for the target platform. Mixing registered and unbuffered modules is not supported.

Questions about this item

How much power does this 1.10V DDR5 module draw when the server runs continuously?

At the rated 1.10 V the module uses less power than previous DDR generations, reducing heat output during all-day operation.

What motherboard slot and memory controller are required for this 288-pin registered DIMM?

A DDR5 RDIMM slot with support for registered ECC modules is needed; the 288-pin keying prevents insertion into other DDR generations.

Will this CL40 4800 MHz stick run at its rated speed alongside slower DDR5 modules already installed?

The memory controller will clock all populated slots to the lowest common speed, so mixing with slower DDR5 reduces this module to that lower rate.
