NEMIX RAM
Eight 16 GB DDR5 4800 ECC registered DIMMs at CL40 and 1.1 V deliver 128 GB for ThinkMate Supermicro servers
This NEMIX RAM kit delivers 128GB of DDR5 ECC RDIMM memory across eight 16GB modules. It is built for THINKMATE Supermicro SuperServer 611C-TN4R and 621C-TN12R systems requiring registered, error-correcting memory. Each module runs at 4800MHz with CL40 latency at 1.1V. The kit is designed for server and workstation workloads demanding data integrity.
This memory suits administrators upgrading compatible THINKMATE SuperServer platforms with registered DDR5 slots. It is not for systems that require unbuffered UDIMM modules or non-ECC memory. Builders needing higher speeds, lower latencies, or consumer desktop compatibility should look elsewhere. The 1Rx8 organisation and 288-pin form factor limit use to matching registered channels.
The decisive specification is the DDR5 4800MHz registered ECC RDIMM standard with CL40 timing. Only motherboards qualified for PC5-38400 registered ECC memory at 1.1V can use this kit. Verify the server memory qualified-vendor list before purchase. The 1Rx8 rank structure and 288-pin interface must match the platform requirements exactly.

The kit runs at the standard DDR5 1.10 V with no heat spreaders, so each 1Rx8 module relies on chassis airflow to stay cool during continuous server workloads.
The memory is validated for THINKMATE Supermicro SuperServer 611C-TN4R and SuperServer 621C-TN12R systems that accept 288-pin DDR5 RDIMMs.
Yes, the 1Rx8 CL40 RDIMMs follow the DDR5 registered specification, allowing them to populate empty slots in the same SuperServer chassis.
