64 GB DDR4 LRDIMM for HPE servers

This module adds 64 GB of DDR4 ECC memory to compatible HPE servers and workstations. It uses a 288-pin LRDIMM form factor with a 4Rx4 rank structure. The load-reduced design helps maintain signal integrity on heavily populated memory channels. It is intended for administrators expanding capacity in supported HPE platforms.

DDR4 2933 MHz interface limits

The DDR4 2933 MHz (PC4-23400) interface sets the maximum data rate for this module. Load-reduced DIMMs reduce electrical load on the memory bus, allowing more modules per channel than standard RDIMMs. However, the platform memory controller and BIOS determine the final operating speed and supported population rules. Mixing ranks or speeds can force the system to run at a lower common frequency.

Capacity headroom and constraints

A single 64 GB module provides substantial capacity for virtualisation, database buffering or large dataset caching. The 4Rx4 organisation delivers high density within one slot, leaving other slots free for further expansion. Systems limited to fewer memory channels or lower maximum capacity per channel may not utilise the full module size. Buyers needing higher per-channel bandwidth or lower latency at smaller capacities should consider alternative rank configurations.

Questions about this item

Should I choose the single 64 GB module or add multiple sticks to reach the capacity I need?

This listing is a single 64 GB LRDIMM. Add one module per available DDR4 slot; each stick provides the full 64 GB capacity.

What does the 2933 MHz rating deliver in an actual HPE server?

The module runs at DDR4 2933 (PC4-23400) with CL21 latency, giving the rated bandwidth when the platform memory controller operates at that speed.

How does the 288-pin LRDIMM interface affect maximum memory per channel?

The 288-pin DDR4 LRDIMM uses load-reduced buffering, allowing higher total capacity per channel than standard RDIMMs while keeping the 1.2 V operating voltage.
