32GB DDR4 2133 ECC RDIMM kit

This 32GB kit contains two 16GB DDR4 2133 ECC Registered DIMMs built for servers and workstations. Each module runs at 1.20V with CL15 latency and a single-rank x4 organisation. The 288-pin form factor fits DDR4 RDIMM slots in compatible enterprise systems.

Upgrade from non-ECC or lower-capacity RDIMMs

Replacing unbuffered or non-ECC memory with this registered ECC kit adds error correction and signal buffering for data integrity under heavy workloads. The dual-channel pair increases total capacity to 32GB when the platform supports 16GB single-rank modules per slot.

Suits DDR4 servers needing registered ECC memory

Builders maintaining DDR4-based servers or workstations that require 1Rx4 RDIMMs at 2133 MT/s will find this kit a direct fit. Systems limited to unbuffered UDIMMs, desktop platforms, laptops or higher-speed DDR4 generations cannot use these modules.

Questions about this item

Will these 288-pin DDR4 RDIMMs fit my server's memory slots?

These are 288-pin DDR4 registered DIMMs, the standard form factor for DDR4 server platforms. They install only in DDR4 RDIMM slots.

What is the correct order for installing the two 16GB modules in a dual-channel kit?

Install one module per memory channel following your system manual's slot sequence, usually the same-coloured slots first, to enable dual-channel operation.

When should I expect to replace these ECC registered modules?

These modules have no heat spreader and run at standard 1.2V; they typically last the server's service life unless a correctable error count rises or a module fails.
