128GB DDR5 ECC RDIMM for Supermicro servers

This 128GB registered DIMM delivers error-correcting DDR5 memory at 6400MHz for Supermicro Hyper SuperServer SYS-122HA-TN-LCC platforms. The single-module design uses 2Rx4 organisation and major OEM chips from Samsung, Micron or Hynix. It targets administrators who need maximum capacity per slot in registered server configurations.

Sustained throughput with CL52 latency and 1.1V

The module runs at CL52 timings and the standard DDR5 voltage of 1.10V, keeping power draw predictable during continuous workloads. Registered buffering reduces electrical load on the memory controller, helping stability when all channels are populated. ECC corrects single-bit errors in real time without halting the system.

DDR5 RDIMM limits defined by 288-pin interface

The 288-pin DDR5 RDIMM form factor fits only DDR5 registered DIMM slots; it cannot be used in unbuffered or previous-generation sockets. Bandwidth is capped at the PC5-51200 specification, so overall throughput scales with the number of populated channels rather than per-module frequency headroom.

Questions about this item

How much heat or power does this 1.10V 6400MHz RDIMM generate when running continuously in a server?

Operating at 1.10V and DDR5 6400MHz, the module draws standard registered DIMM power for its density; the 2Rx4 organisation and lack of a heat spreader mean it relies on chassis airflow for cooling.

What motherboard slot and platform are required for this 288-pin DDR5 RDIMM to function?

It needs a DDR5 RDIMM 288-pin slot on a Supermicro Hyper SuperServer SYS-122HA-TN-LCC or compatible board that supports registered ECC memory at PC5-51200.

Can this 128GB 2Rx4 CL52 module be mixed with other registered ECC RDIMMs of different capacity or rank in the same system?

Mixing is possible only if the platform's memory controller supports heterogeneous population rules; the module itself is a single 128GB 2Rx4 rank at CL52, so any companion DIMMs must match voltage, speed and registered ECC type.
