System-Specific DDR5 Kit

This 512GB kit contains eight 64GB DDR5 registered DIMMs validated for the Supermicro SYS-122HA-TN-LCC platform. It targets administrators who need maximum ECC capacity in that specific server chassis.

Build Integration

Each module uses the 288-pin DDR5 RDIMM form factor and operates at 1.1V with a 2Rx4 organisation. The registered buffer and on-die ECC reduce electrical load on the memory controller, freeing signal margin for the full eight-channel population.

Sustained Load Behaviour

Rated at 6400MHz PC5-51200 with CL52 latency, the modules maintain specified throughput during continuous enterprise workloads. Major-brand Samsung, Micron or Hynix DRAM ensures consistent timing stability without thermal throttling in dense configurations.

Questions about this item

Does CL52 latency limit sustained throughput on the DDR5 6400MHz RDIMMs?

CL52 is the rated CAS latency; sustained throughput depends on the Supermicro SYS-122HA-TN-LCC memory controller and workload, not on the module latency alone.

How much heat or power do the 1.1V 2Rx4 modules generate under all-day load?

Each module runs at 1.10V; total kit power scales with all eight 64GB DIMMs active, and registered ECC buffering adds minor controller overhead.

What must the Supermicro SYS-122HA-TN-LCC already have to accept this 512GB kit?

The board needs eight free 288-pin DDR5 RDIMM slots and a BIOS that supports 2Rx4 registered ECC modules at 6400MHz.
