Purpose-built server memory

This 64 GB DDR5 registered DIMM is designed for THINKMATE Supermicro SuperServer 111C-NR and 121C-TN2R platforms. ECC protection and registered buffering target workloads that require data integrity over raw latency. The single-module layout lets administrators populate slots incrementally without mixing capacities. Buyers who need unbuffered UDIMMs or consumer SO-DIMMs should look elsewhere.

Build and connectivity

A 288-pin edge connector mates with standard DDR5 RDIMM sockets on qualified server boards. The 2Rx4 organisation uses major OEM Samsung, Micron or Hynix die behind a thin green PCB with no heat spreader. Registered signalling reduces electrical load on the memory controller, allowing larger populations per channel. Systems that require low-profile modules or tall heatspreaders for active airflow may need a different form factor.

Thermals, noise and power

Rated at 1.1 V, the module runs at the baseline DDR5 voltage without overclock headroom. Passive operation means zero acoustic contribution inside a chassis that already relies on forced-air cooling. Power draw scales with the 4800 MT/s data rate and CL40 latency under sustained server loads. Environments with restricted airflow or fanless designs must verify thermal margins independently.

Questions about this item

Does the DDR5 4800 RDIMM run at its rated 4800 MT/s on a ThinkMate Supermicro SuperServer 111C-NR?

The module is specified for DDR5 4800 (PC5-38400) with CL40 timing and 1.10 V operation on compatible ThinkMate Supermicro SuperServer 111C-NR and 121C-TN10R platforms.

Will the 288-pin 2Rx4 registered DIMM fit the memory slots in a ThinkMate Supermicro SuperServer 121C-TN2R?

This is a 288-pin DDR5 RDIMM with 2Rx4 organisation and no heat spreader, matching the registered DIMM slot layout used in the listed ThinkMate Supermicro SuperServer models.

What is the correct installation sequence for a single 64 GB registered ECC module in these servers?

Install the module in the primary DIMM slot for the first memory channel as shown in the server manual, ensure the ejector clips lock fully, and verify ECC registered mode is enabled in BIOS before boot.
