Capacity and Form Factor

This is a single 64GB DDR4 2400 LRDIMM built for HP server and workstation platforms that accept load-reduced registered memory. The 288-pin module delivers ECC protection and a 4Rx4 organisation for high-density configurations.

Speed and Voltage Constraints

The module runs at the standard DDR4 2400 MT/s data rate with a CL17 latency and operates at the JEDEC 1.20 V level. Systems limited to lower DDR4 speeds or different voltage rails will not support this part.

Rank Architecture Decides Fit

The 4Rx4 rank structure determines whether the memory controller can address the full capacity; platforms that only support single- or dual-rank LRDIMMs cannot use this module.

Questions about this item

Should I choose the 64 GB module or a smaller capacity for my HP server?

This is a single 64 GB DDR4 2400 ECC LRDIMM; select it when your system needs that capacity in one slot and supports Load Reduced modules.

What does the DDR4 2400 speed deliver once installed?

The module runs at 2400 MHz with CL17 latency at 1.20 V, giving the bandwidth and timing specified for PC4-19200 operation.

How does the LRDIMM interface affect maximum memory scaling?

The 4Rx4 Load Reduced design reduces electrical load on the memory bus, allowing higher total capacity than standard RDIMMs on supported platforms.
