64GB DDR4 2400MHz ECC LRDIMM Server Memory

This 64GB module provides high-capacity DDR4 memory for server and workstation systems that require error-correcting code and load-reduced technology. It operates at 2400MHz with a CAS latency of CL17 and a standard voltage of 1.20V. The 4Rx4 rank configuration and Micron chipset ensure dependable performance for demanding workloads.

DDR4 2400MHz Interface Constraints

The DDR4 2400MHz standard limits this module to a maximum transfer rate of PC4-19200. Systems with memory controllers that only support lower DDR4 speeds will downclock the module, while platforms requiring higher speeds cannot utilise its full rated frequency. The 288-pin DIMM form factor fits only compatible DDR4 server slots.

4Rx4 Load-Reduced ECC Architecture

The 4Rx4 load-reduced design places an electrical buffer on the module to reduce signal loading on the memory bus, allowing higher densities per channel. This architecture is mandatory for systems that require LRDIMM topology and will not function in platforms limited to standard RDIMM or UDIMM populations. Buyers needing single-rank or standard registered modules cannot use this part.

Questions about this item

Should I pick the 64GB LRDIMM or combine smaller RDIMMs to reach the same capacity?

This module is a single 64GB DDR4 2400MHz ECC LRDIMM with a 4Rx4 organisation, designed for servers that support Load Reduced DIMMs.

What does the DDR4 2400MHz rating mean for actual throughput in my server?

The module runs at 2400 MT/s with CL17 latency at 1.20V, delivering the standard DDR4 2400 data rate for ECC-protected workloads.

Does the 288-pin DDR4 interface limit the speed or features I can use?

The 288-pin DDR4 DIMM form factor carries the 2400 MT/s signal and ECC LRDIMM protocol; the platform’s memory controller determines the final operating speed.
