NEMIX RAM
A 128 GB DDR4 3200 ECC registered dual-rank kit in two 64 GB modules for ThinkMate GPU-optimised servers
This NEMIX RAM kit provides 128GB of DDR4 3200 registered ECC memory in a two-module configuration. Each 64GB module operates at 1.2V with CL22 latency and uses a 4Rx4 organisation. The 288-pin RDIMM form factor is built for server motherboards that require registered DIMMs with error-correcting code support.
Administrators expanding memory in the specified ThinkMate platform will find this kit validated for compatibility. Systems that require unbuffered UDIMMs, non-ECC modules, or a different DDR generation cannot use these registered ECC RDIMMs. Buyers needing lower capacities or consumer desktop memory should look at other product lines.
Check the motherboard documentation for maximum supported capacity per slot and total system limit before ordering. Confirm the platform supports 4Rx4 module organisation and 1.2V operation. Ensure the BIOS version in use recognises 64GB registered DIMMs and that the memory controller can address the full 128GB kit.

Yes, the kit is validated for THINKMATE GPX-XT6-24S3-8NVLINK GPU-optimised servers; other platforms are not qualified by the supplier.
Mixing different rank configurations is not recommended; the server memory controller typically requires identical rank-per-channel layouts for stable operation.
Check the BIOS memory information screen or OS tools such as dmidecode to verify speed shows 3200 MT/s, ECC is enabled and total capacity reads 128 GB.
