Thinkmate RAX-XS4-21S4 Compatible Memory

This 64 GB kit is built for the Thinkmate RAX-XS4-21S4 rackmount server. It delivers two 32 GB DDR5 4800 registered ECC modules that install in minutes and are validated for mission-critical workloads.

Who Should Use This and Who Should Not

IT teams running the specified Thinkmate platform gain error-correcting registered memory at 1.1 V without compatibility guesswork. Buyers who need unbuffered UDIMM modules, a different DDR5 speed grade, or memory for any other server model should look elsewhere.

The Deciding Specification

Registered ECC RDIMM with 2Rx8 organisation and CL40 latency at DDR5 4800 is the single attribute that determines fit. Only systems that require this exact registered ECC configuration will accept the kit.

Questions about this item

Should I choose the 64 GB kit or a different capacity for my ThinkMate RAX‑XS4‑21S4?

This kit provides 64 GB as two 32 GB modules, matching the server's validated configuration for registered ECC memory.

What does the DDR5 4800 speed mean once installed in the ThinkMate server?

The modules run at 4800 MT/s with CL40 latency at 1.10 V, delivering the rated PC5‑38400 bandwidth in the registered ECC configuration.

How does the 288‑pin RDIMM interface affect compatibility and performance?

The 288‑pin DDR5 RDIMM form factor with 2Rx8 organisation and registered ECC is the exact interface the ThinkMate RAX‑XS4‑21S4 requires for stable server operation.
