System-specific DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 64 GB of DDR5 4800 registered ECC memory in a matched pair of 32 GB modules. It is built for ThinkMate server and workstation platforms that require 288-pin RDIMM modules with error correction. The modules operate at 1.1 V with CL40 latency and use a 2Rx8 organisation.

Suited for ThinkMate RAX and Q-series servers

This memory fits administrators upgrading ThinkMate RAX-QE12, QS12, QH12, QT12, QT16, QH24, QH4, QN12 or QH8 systems that support DDR5 RDIMM slots. It is not for desktop motherboards, laptops or any platform that accepts only unbuffered UDIMM modules or a different DDR generation.

Registered ECC with 2Rx8 organisation

The decisive specification is the registered ECC RDIMM design with 2Rx8 rank structure, which the target ThinkMate server chipsets require for stability and capacity scaling. Buyers whose systems need UDIMM, LRDIMM or a different rank configuration must choose another part.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the ThinkMate RAX-QE12 server?

Yes, the 288-pin DDR5 RDIMM is built for ThinkMate RAX-QE12, QS12, QH12, QT12, QT16, QH24, QH4, QN12 and QH8 servers.

What is the correct slot order when installing the two 32 GB modules?

Install the two 32 GB modules in the channels specified by the ThinkMate motherboard manual; the common mistake is populating a single channel instead of using both channels.

Will the Samsung, Micron or Hynix chips on these ECC RDIMMs need replacement?

The ECC RDIMMs are stress-tested for server workloads and are not a scheduled replacement item; replace only if a module fails.
