NEMIX RAM 64GB (2x32GB) DDR5 4800 ECC RDIMM THINKMATE memory upgrade

64GB DDR5 ECC RDIMM kit for THINKMATE servers

This NEMIX RAM kit supplies 64GB of DDR5 4800 registered ECC memory across two 32GB modules. It targets IT professionals upgrading THINKMATE Supermicro SuperServer 611C-TN4R and 621C-TN12R platforms that require registered DIMMs with error correction. The 1.1V operating voltage matches the DDR5 server standard.

DDR5 4800 registered ECC limits

The DDR5 4800 interface caps module speed at 4800MT/s with a CL40 latency profile. Registered buffering adds one clock cycle of address-command delay, which is mandatory for the target SuperServer platforms but prevents use in unbuffered consumer boards. ECC functionality depends on motherboard support; systems without ECC logic will ignore the parity bits.

Two-module installation in server chassis

Installing the 288-pin RDIMMs follows the server board population rules documented in the SuperServer manual; mismatched slot order is the most common cause of post failures. Modules lack heat spreaders, so airflow across the DIMM rows must be maintained by the chassis fans. Mixing these 1Rx4 sticks with different ranks or capacities can disable multi-channel operation.
