Server-grade DDR5 RDIMM

This 32GB Kingston DDR5 module is built for server motherboards that require registered ECC memory. The dual-rank 2Rx8 organisation and 288-pin RDIMM form factor make it a direct fit for multi-socket platforms needing error correction and signal buffering.

Registered ECC with CL40 latency

The single specification that decides compatibility is the registered ECC design combined with CL40 timing at 4800 MT/s. Only systems that explicitly support DDR5 RDIMM modules with on-die ECC and registered signalling can use this part; unbuffered or non-ECC boards will not accept it.

Fits DDR5 RDIMM slots at 1.10 V

Installation requires a server board with DDR5 RDIMM slots operating at the standard 1.10 V. The module has no heat spreader, so airflow across the DIMM area must be adequate. It frees the builder from sourcing separate ECC and buffering components because both functions are integrated on the stick.

Questions about this item

How does the 4800 MHz speed translate to real-world server performance?

The module runs at DDR5-4800 with CL40 timing (40-39-39) at 1.10 V, delivering the rated data rate when the platform memory controller is configured for that speed.

What does the PC5-38400 designation mean for bandwidth limits?

PC5-38400 is the JEDEC standard name for DDR5-4800; the memory controller and channel population determine the usable bandwidth in your server.

Will the 288-pin registered DIMM fit my server motherboard slots?

This is a 288-pin DDR5 RDIMM with 2Rx8 organisation and no heat spreader; it requires DDR5 RDIMM slots that support registered ECC modules.
