Server-grade ECC LRDIMM kit

This OWC kit supplies 64GB of DDR4 memory in a matched pair of 32GB modules. Each stick is a 288-pin load-reduced DIMM with ECC and a 4Rx4 organisation, built for servers, workstations and NAS systems that require registered error-correcting memory. It will not work in standard desktop platforms or alongside unbuffered DIMMs.

Thermals and power profile

Operating at 1.2V, the modules run at the standard DDR4 voltage for reduced power draw in densely populated memory channels. No heat spreader is fitted, so airflow across the bare PCB manages thermals in typical server chassis. Backward compatibility with 2133MHz systems allows the kit to clock down automatically when installed in older platforms.

Build integration notes

The dual-channel kit occupies two DIMM slots and delivers 64GB total capacity for memory-intensive workloads. Compliance with JEDEC PC4-19200 specifications ensures broad OEM compatibility, while the load-reduced design lowers electrical load on the memory controller. Buyers needing unbuffered memory, non-ECC operation or desktop consumer platforms cannot use this product.

Questions about this item

How do I install the 288-pin LRDIMM modules and what step is often missed?

Power off the server, open the chassis, align each 288-pin module with the slot key and press firmly until the retention clips click; the step often missed is confirming the platform requires Load Reduced ECC memory and will not accept unbuffered DIMMs.

What maintenance or replacement will this 64GB kit need over time?

No routine maintenance is required; if a module fails it is replaced individually under the manufacturer's limited lifetime warranty, and the dual-channel kit means you can swap a single 32GB stick without breaking the pair.

What limit appears first when the 2400MHz CL17 LRDIMMs run under sustained load?

The CAS latency of CL17 at 1.2V sets the timing ceiling; sustained throughput is bounded by the DDR4 2400 PC4-19200 data rate and the 4Rx4 rank organisation, which the memory controller manages automatically.
