NEMIX RAM
Eight 128 GB DDR5 4800 CL40 1.1 V 4Rx4 ECC registered DIMMs totalling 1 TB for Thinkmate 611C-TN4R and 621C-TN12R servers
This NEMIX RAM kit delivers 1 TB of registered DDR5 memory across eight 128 GB modules. It runs at 4800 MT/s with CL40 latency at 1.1 V and includes on-die ECC for data integrity. The modules are 288-pin RDIMMs built with major OEM DRAM and are validated for Thinkmate SuperServer 611C-TN4R and 621C-TN12R platforms.
The kit targets administrators expanding memory in the listed Thinkmate SuperServer models where registered ECC DDR5 is required. Buyers needing unbuffered UDIMMs, lower-density modules, or compatibility with other server brands should look at something else.
The single specification that decides fit is the 1 TB capacity delivered as eight 128 GB registered DIMMs; the motherboard must support 4Rx4 organisation and the full population of eight slots at DDR5 4800.

The 1TB kit provides eight 128 GB modules for maximum supported capacity; choose a smaller kit only if your workload does not need the full 1 TB.
The modules run at DDR5 4800 with CL40 latency, delivering the rated PC5-38400 bandwidth when the platform operates at its default memory speed.
The 288-pin registered DDR5 form factor is the native interface for these servers, so the memory operates at the full 4800 MHz without down-clocking.
