NEMIX RAM
Adds 256 GB of DDR5 ECC registered memory across eight 32 GB modules at 4800 MT/s for Thinkmate servers
This NEMIX RAM kit provides 256GB of DDR5 4800 registered ECC memory across eight 32GB modules. It is built for THINKMATE SuperServer 611C-TN4R and 621C-TN12R platforms that require 288-pin RDIMM modules with 1Rx4 organisation. The modules operate at 1.10V with CL40 latency and contain no heat spreaders.
This memory fits the two listed SuperServer models that accept DDR5 4800 ECC RDIMM modules in eight-slot configurations. It is not for systems that use unbuffered UDIMM memory, require a different DDR generation, or need fewer than eight modules to reach the desired capacity. Buyers with other server brands or desktop platforms should verify their exact memory specifications first.
Only motherboards wired for 288-pin DDR5 registered DIMMs at 4800 MT/s can use this kit. The 1Rx4 rank structure and 1.10V operating voltage are fixed by the module design and must match the server memory controller requirements. If the target system calls for a different speed, voltage, or module type, this kit will not function.

Yes, the modules run at DDR5 4800 (PC5-38400) and the platform will operate them at that speed.
The kit uses standard 288-pin DDR5 RDIMMs, which match the registered DIMM slots in those ThinkMate SuperServer models.
Populate the slots following the motherboard's channel sequence — usually one DIMM per channel per CPU — and seat each module until the retention clips click.
