32GB DDR4-2400 ECC Registered Kit

This 32GB kit contains two 16GB DDR4 modules rated at 2400 MT/s with PC4-19200 bandwidth. Each module uses a 288-pin registered DIMM layout with ECC and a 2Rx4 organisation. It is built for servers and workstations that require error correction and signal buffering.

Upgrading from non-ECC or unbuffered memory

Systems running consumer UDIMMs cannot use these registered modules; the memory controller must support registered DIMMs and ECC. The jump is worth it when data integrity and larger per-channel capacity are required for virtualisation, databases or long-running compute tasks.

32GB capacity with dual-rank density

Two dual-rank 16GB DIMMs fill two slots and leave remaining channels open for further expansion. The registered design reduces electrical load on the memory controller, allowing higher total system capacities than unbuffered alternatives. Workloads exceeding 32GB will need additional modules.

Questions about this item

Will these 288-pin DDR4 modules fit my server's DIMM slots?

Yes, each 16 GB stick uses the standard 288-pin DDR4 form factor used by registered server boards.

What is the correct order for populating the two 2Rx4 sticks during installation?

Install the pair in the same memory channel, typically slots 1 and 3 or 2 and 4, following the motherboard manual's ranked-population guide.

When should I plan to replace this 32 GB kit in a 24/7 server?

Registered ECC DDR4 modules commonly run five to seven years before preventive replacement is considered.
