Server-grade DDR4 LRDIMM for enterprise workloads

This 32GB OWC module uses DDR4 2400MHz CL17 load-reduced ECC technology on a 288-pin form factor. It targets administrators upgrading servers, workstations or NAS systems that require registered memory with error correction. The single 32GB stick operates at 1.2V and carries a 4Rx4 rank configuration for high-density slots.

Load-reduced design limits mixing and platform fit

LRDIMM architecture buffers both data and address lines, so this module cannot be combined with unbuffered or standard registered DIMMs in the same system. It runs at PC4-19200 speed and will downclock to 2133MHz when the platform demands it. JEDEC compliance ensures baseline interoperability, but the memory controller must explicitly support load-reduced topology.

Verify slot type, rank allowance

Before ordering, confirm your motherboard accepts 288-pin DDR4 LRDIMMs and permits 4Rx4 modules in the target slots. Check the qualified vendor list for 32GB density at 2400MHz and note any channel-population limits that restrict total rank count per channel. Mixing with other rank counts or unbuffered memory is not supported.

Questions about this item

Is this a single 32GB module or a kit of multiple sticks?

It is a single 32GB DDR4 2400MHz PC4-19200 CL17 4Rx4 ECC Load Reduced LRDIMM 1.2V 288-pin module.

Will the 2400MHz speed actually run at that frequency in my server?

The module is rated for DDR4 2400 (PC4-19200) CL17 and also compatible with 2133MHz systems, running at the speed your platform supports.

What does the Load Reduced ECC LRDIMM interface mean for my system?

Load Reduced ECC LRDIMM reduces electrical load on the memory bus, allowing higher capacity per channel in servers and workstations; it cannot be mixed with unbuffered memory.
