128GB DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 128GB of DDR5 registered memory across four 32GB modules. It runs at 4800MHz with CL40 latency and 1.1V operation. The 2Rx8 ECC RDIMM design targets ThinkMate RAX-XS4-21S4 rackmount servers requiring registered error-correcting memory.

Suited for ThinkMate server upgrades

IT administrators expanding capacity in compatible ThinkMate RAX-XS4-21S4 systems will find this matched quad-channel kit straightforward to install. Builders needing unbuffered UDIMMs, non-ECC modules, or different form factors such as SODIMM should look elsewhere.

Registered ECC with 2Rx8 organisation

The registered buffer and ECC functionality are mandatory for the target platform; systems expecting unregistered or non-ECC memory will not accept these modules. Verify your server requires DDR5 RDIMM before purchasing.
