768GB DDR4 3200 ECC RDIMM Kit

This NEMIX RAM kit provides 768GB of DDR4 3200MHz registered ECC memory in six 128GB modules. It is built for THINKMATE rackmount servers that require high-capacity, error-correcting registered DIMMs. The modules run at 1.2V with CL22 latency and use 4Rx4 organisation. They are designed for enterprise workloads where data integrity and maximum density per slot are priorities.

Suited for THINKMATE RAX servers needing maximum RAM

This kit targets the THINKMATE RAX-XS4-21S1-10G, RAX-XS4-11S1-10G and RAX-XH2-11S3 platforms listed in the compatibility data. It is not for consumer desktops, laptops or workstations that accept only unbuffered non-ECC UDIMMs. It is also not for systems limited to lower per-slot capacities or those that cannot address 4Rx4 registered modules. Buyers needing non-ECC memory or standard UDIMM form factors should look elsewhere.

768GB total across six slots for heavy workloads

The six 128GB RDIMMs deliver 768GB total capacity, allowing large in-memory databases, virtualisation clusters and high-throughput analytics to run without swapping. Each module operates at DDR4 3200 (PC4-25600) with ECC protection active. Headroom ends when the server's memory controller reaches its maximum supported density per channel or total system limit; beyond that point additional modules cannot be addressed.

Questions about this item

Which Thinkmate rackmount servers accept this 768GB DDR4-3200 ECC RDIMM kit?

The kit is validated for Thinkmate RAX-XS4-21S1-10G, RAX-XS4-11S1-10G and RAX-XH2-11S3 rackmount servers.

Can I mix these 4Rx4 128GB modules with existing 2Rx4 or 2Rx8 DDR4-3200 RDIMMs in the same server?

Mixing different rank configurations is not recommended; the server's memory controller expects identical 4Rx4 modules across all populated channels for stable operation.

How do I confirm the full 768GB is recognised and running at 3200 MT/s with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode — each of the six slots should show 128GB, 3200 MT/s, registered ECC, 1.20 V and CAS 22.
