High-Density Server Memory

This 64GB DDR4-2666 LRDIMM is built for HP-compatible servers that need maximum installed capacity. The load-reduced design places less electrical load on the memory bus, allowing denser population of DIMM slots. ECC protection and 1.20V operation suit enterprise workloads that demand data integrity.

Upgrade from Smaller Modules

Replacing lower-capacity RDIMMs or LRDIMMs with these 64GB modules lets you fill fewer slots for the same total memory, or reach higher totals when every slot is occupied. The jump is worth it when current memory limits the number of virtual machines or causes frequent swapping and paging.

64GB Capacity Headroom

A single module delivers 64GB at CL15 latency, supporting large in-memory databases, dense virtualization hosts and heavy analytics jobs. Headroom ends when the platform's maximum memory per socket or total slot count is reached, or when workloads need speeds beyond DDR4-2666.

Questions about this item

What slot type does the 288-pin DDR4 LRDIMM require?

The module fits a standard 288-pin DDR4 DIMM socket on the server motherboard.

How do I install the LRDIMM correctly, and what step is often missed?

Align the notch with the socket key, press firmly until both retention clips click, then verify the BIOS recognises the full 64GB at DDR4-2666.

When should the LRDIMM be replaced or serviced?

No scheduled maintenance is required; replace only if memory diagnostics report uncorrectable ECC errors or the module fails to initialise.
