Server ECC UDIMM for DDR4 platforms

This 16 GB DDR4 2400 ECC UDIMM module is built for servers and workstations that require error-correcting unbuffered memory. The dual-rank 2Rx8 organisation and CL17 latency deliver reliable throughput for multi-threaded workloads. It operates at the standard 1.2 V DDR4 voltage and fits 288-pin DIMM slots. Desktop and laptop systems cannot use this module.

Upgrade from non-ECC or lower capacity

Replacing standard unbuffered memory without error correction adds data-integrity protection for critical applications. Moving from an 8 GB module to this 16 GB stick doubles per-slot capacity, reducing the number of populated slots needed for a given total. The jump is worth it when your workload exceeds current memory headroom or when ECC becomes a requirement for data accuracy.

DDR4 2400 interface limits

The PC4-19200 rating caps maximum bandwidth at the DDR4 2400 MT/s data rate, so faster DDR4 speeds will downclock to this frequency. Mixing ranks or speeds across channels can further restrict achievable throughput. ECC UDIMM topology also limits maximum module count per channel compared to registered DIMMs, constraining total system capacity on some platforms.

Questions about this item

Does the 288-pin DDR4 DIMM fit a standard server UDIMM slot?

Yes, the 288-pin DDR4 DIMM matches the standard UDIMM slot used by DDR4 servers and workstations that support ECC unbuffered memory.

What is the correct way to seat this ECC UDIMM, and what step do installers often miss?

Align the notch with the slot key, press firmly until both retention clips click, then verify the module is fully seated by checking the clips are locked; many forget to engage both clips evenly.

Will the 2Rx8 dual-rank modules need any firmware updates or replacement after prolonged server use?

No firmware updates are required for the memory itself; the modules are tested for reliable long-term operation at 1.2 V and CL17 latency.
