ThinkMate RAX-XS4-21S4 server memory kit

This 384GB kit contains twelve 32GB DDR5 4800 registered ECC RDIMM modules built for the ThinkMate RAX-XS4-21S4 rackmount server. It targets IT teams who need maximum supported capacity in that specific platform. The modules run at 1.1V with CL40 latency and use a 2Rx8 organisation.

DDR5 4800 registered ECC RDIMM specification

The single specification that decides fit is the DDR5 4800 registered ECC RDIMM form factor with 2Rx8 ranking and 1.1V operation. Only systems that accept this exact module type and speed will post correctly; desktop or unbuffered memory will not work.

Twelve-module kit simplifies deployment

The package delivers all twelve 32GB modules in one matched kit so the server can be fully populated in a single maintenance window. No additional accessories or software are included beyond the memory modules themselves.

Questions about this item

Will 4800 MT/s run at that speed in my Thinkmate RAX-XS4-21S4?

The kit is rated DDR5-4800 (PC5-38400) CL40; the server’s memory controller will set the final speed, but the modules are validated for 4800 MT/s operation at 1.10 V.

Is the registered ECC design required for the Thinkmate RAX-XS4-21S4?

Yes — the modules are 288-pin DDR5 RDIMM with on-die ECC and register buffers, matching the registered ECC requirement of the Thinkmate RAX-XS4-21S4 platform.

Do the 12 sticks fit the 288-pin DDR5 slots without a heat-spreader?

Each 32 GB module is a standard-height 288-pin DDR5 RDIMM without a heat spreader, so all 12 install directly into the server’s DDR5 DIMM sockets.
