32 GB DDR5 ECC RDIMM kit

This 32 GB kit contains two 16 GB DDR5 4800 registered DIMMs built for ThinkMate Supermicro SuperServer 111C-NR and 121C-TN10R platforms. Error-correcting code and registered buffering protect data integrity in mission-critical workloads. The modules operate at 1.1 V and carry a CL40 latency rating. Buyers needing non-ECC consumer memory or higher-frequency kits should look elsewhere.

Sustained-load behaviour

Each module uses 1Rx8 organisation with major OEM Samsung, Micron or Hynix chips validated under extended stress testing. Registered signalling reduces electrical load on the memory controller during continuous throughput. ECC detection corrects single-bit errors without interrupting service. The kit targets stable 4800 MT/s operation rather than short burst overclocks.

Build and daily implications

The 288-pin RDIMM form factor fits standard DDR5 server slots without a heat spreader, allowing tight multi-DIMM population. Registered buffers add a clock cycle of latency but improve signal integrity in dense configurations. Compatibility is limited to the listed ThinkMate SuperServer models; other platforms require separate verification.

Questions about this item

How much power does the 1.10 V DDR5 kit draw when the server runs continuously?

Each module operates at 1.10 V, the standard DDR5 voltage, so total power scales with the 32 GB capacity and 4800 MT/s data rate rather than a higher voltage.

What motherboard feature must the ThinkMate system provide for these registered ECC DIMMs to function?

The board needs a DDR5 RDIMM slot with registered-buffer and ECC support; standard unbuffered consumer slots will not accept the 288-pin registered modules.

Will the CL40 1Rx8 sticks work in the Supermicro SuperServer 111C-NR alongside any existing DDR5 RDIMMs?

Yes, provided the other modules are also DDR5 ECC RDIMMs; mixing ranks or speeds is supported by the platform but all slots must use registered DDR5.
