192GB DDR5 ECC RDIMM kit for Supermicro

This registered ECC memory kit provides 192GB across six 32GB modules. It is built for the Supermicro Hyper SuperServer SYS-122HA-TN-LCC platform. The dual-rank DDR5 RDIMMs operate at 1.1V with CL52 latency. It suits administrators expanding capacity in that specific server model.

Sustained-load behaviour of DDR5 6400MHz CL52

Registered buffering and on-die ECC maintain data integrity during continuous server workloads. The 1.1V operating voltage supports stable throughput under prolonged utilisation. Dual-rank 2Rx8 organisation allows the memory controller to interleave accesses across ranks. CL52 timing remains consistent without the voltage scaling seen in consumer modules.

Practical limits of the DDR5 RDIMM interface

The 288-pin DDR5 RDIMM form factor fits only DDR5-compatible registered DIMM slots. Maximum kit capacity is defined by the six-module 192GB configuration. Registered signalling adds one clock cycle of latency versus unbuffered modules. ECC functionality requires a platform that supports error-correcting registered memory.

Questions about this item

How much power does the 6400MHz DDR5 kit draw at 1.1V when the server runs continuously?

Each 32GB module operates at 1.10V, so the six-module kit runs at standard DDR5 voltage without elevated power draw under sustained load.

What must the Supermicro SYS-122HA-TN-LCC already have to accept this 288-pin RDIMM kit?

The motherboard needs six free DDR5 RDIMM slots and a CPU that supports registered ECC memory at 6400MHz.

Will the CL52 2Rx8 modules work alongside any existing DDR5 RDIMMs I keep in the same server?

Mixing ranks or latencies can prevent the system from posting; populate all six slots with this matched 192GB kit for stable operation.
