Server-grade 64 GB DDR4 LRDIMM

This 64 GB DDR4 module is built for servers and workstations that require ECC load-reduced memory. It operates at 3200 MHz with CL22 latency and 1.20 V standard voltage. The 288-pin LRDIMM form factor uses a 4Rx4 quad-rank x4 organisation with major-brand chips. It is not compatible with desktop or laptop computers.

DDR4 3200 interface and platform limits

The module runs at the DDR4 3200 (PC4-25600) data rate and presents a quad-rank electrical load per DIMM slot. System memory controllers must support LRDIMM buffering and 4Rx4 rank multiplication to address the full capacity. Maximum usable speed and total installed memory depend on the specific server or workstation platform and its qualified vendor list.

Capacity headroom for virtualisation and databases

A single 64 GB module provides substantial headroom for memory-intensive workloads such as virtualisation hosts, in-memory databases and large-scale analytics. Multiple modules can scale total system memory into the multi-terabyte range where the platform allows. Workloads that exceed per-channel rank limits or total socket capacity will require a platform with higher memory-channel count or larger DIMM support.

Questions about this item

Should I pick a single 64GB module or combine smaller modules to reach 64GB?

This listing is a single 64GB LRDIMM; adding more modules depends on your server's slot count and maximum supported capacity per channel.

What does the 3200 MHz rating deliver in an actual server workload?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency, giving higher bandwidth for memory-intensive tasks when the platform supports that speed.

How does the LRDIMM interface affect compatibility and performance limits?

Load Reduced DIMM buffers the data lines, lowering electrical load on the memory controller so servers can populate more slots at 3200 MHz without signal degradation.
