Thinkmate RAX-XS4-21S4 compatible DDR5 kit

This 96 GB kit delivers six 16 GB DDR5 4800 RDIMM modules built for the Thinkmate RAX-XS4-21S4 rackmount server. Registered ECC operation protects data integrity in mission-critical workloads. The 1.1 V modules run at PC5-38400 speed with CL40 latency. IT teams can install the kit in minutes using standard 288-pin slots.

96 GB capacity with registered ECC headroom

Six single-rank 1Rx8 modules provide 96 GB total capacity for virtualisation, database and compute tasks. Registered buffering reduces electrical load on the memory controller, allowing full population of all channels. The kit handles sustained enterprise workloads without parity errors. Capacity limits are reached when the server's maximum supported memory per processor is exceeded.

DDR5 4800 RDIMM interface constraints

The DDR5 4800 interface sets the peak transfer rate at PC5-38400 with CL40 timing. Registered DIMMs add one clock cycle of address/command buffering, which slightly increases latency versus unbuffered modules. Bandwidth scales with the number of populated channels on the server platform. The 288-pin form factor fits only DDR5 RDIMM slots and cannot be used in UDIMM or previous-generation sockets.

Questions about this item

Will the six 16 GB DDR5 4800 CL40 RDIMMs work together with any DDR5 modules already installed in the THINKMATE RAX-XS4-21S4?

The kit contains six 1Rx8 registered ECC modules rated at DDR5 4800 with CL40 latency and 1.10 V operation; adding them to other DDR5 RDIMMs of the same speed, voltage and rank organisation will keep the channel stable.

How can I verify the 96 GB kit is running at the rated 4800 MT/s and CL40 timings after installation?

Check the BIOS memory information screen or a tool such as CPU-Z — it should report DDR5 4800 (PC5 38400), CAS latency 40, 1.10 V and registered ECC mode for all six modules.

Does the MR38400-618K6 package include only the six 288-pin RDIMMs or are any cables or brackets supplied?

The box holds the six 16 GB DDR5 4800 ECC RDIMMs and nothing else; no cables, brackets or additional hardware are included.
