System-specific 32 GB DDR5 module

This 32 GB DDR5 registered DIMM is built for the THINKMATE RAX-XS4-21S4 rackmount server. It delivers ECC protection and registered signalling for workloads that require data integrity and stable operation in multi-slot configurations.

Fits a single 288-pin DDR5 slot at 1.1 V

The module occupies one RDIMM slot and runs at the standard 1.10 V, leaving remaining slots free for further capacity expansion. Its 2Rx8 organisation works with the server's memory controller without requiring additional cooling hardware.

Sustained throughput at 4800 MT/s with CL40 latency

Rated at 4800 MT/s (PC5-38400) and CL40, the module maintains rated bandwidth during extended compute or virtualisation tasks. ECC correction and registered buffering keep error rates low under continuous load.

Questions about this item

Will the 1.10V operating voltage limit headroom during sustained server workloads?

The module runs at the standard DDR5 1.10V, which is the JEDEC voltage for 4800 MT/s operation and does not restrict sustained throughput.

How much heat does a registered 2Rx8 module generate when running continuously in a rack chassis?

The RDIMM has no heat spreader and draws 1.1V at CL40; registered buffering keeps power per module low enough for typical server airflow.

Does the ThinkMate RAX-XS4-21S4 need any specific BIOS setting or firmware revision before this RDIMM will post?

The part number MR38400-328K1 is validated for the RAX-XS4-21S4 and installs without additional configuration.
