Capacity and Compatibility

This 384GB kit delivers six 64GB DDR5 modules validated for the Supermicro SYS-422GS-NBRT-LCC GPU SuperServer. Registered ECC RDIMM construction ensures data integrity for mission-critical workloads. The modules operate at 6400MHz with CL52 latency at 1.1V. Builders targeting other platforms or non-ECC consumer boards should select a different kit.

Thermals and Power

Bare modules without heat spreaders rely on server chassis airflow for cooling in normal operation. The 1.1V DDR5 voltage reduces power draw per module compared with previous DDR generations. Registered buffering adds negligible latency while stabilising heavy memory loads across all populated slots. Environments with restricted airflow may require directed cooling.

Build Integration

The 288-pin RDIMM form factor occupies six DIMM slots in the supported Supermicro system. 2Rx4 organisation maximises density within the platform memory architecture. ECC and registered features require a compatible server chipset and BIOS. Systems lacking DDR5 RDIMM support or the specified Supermicro validation cannot use this kit.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the Supermicro SYS-422GS-NBRT-LCC, and what step is often missed?

Power down the server, open the chassis, align each 288-pin DDR5 RDIMM with the slot key notch, press firmly until both retention clips click, then verify all six 64 GB modules are recognised in the BIOS memory map before closing the case.

What maintenance or replacement will the 384 GB DDR5 ECC RDIMM kit need over its service life?

The registered ECC modules have no moving parts and require no scheduled maintenance; replacement is only necessary if a module fails, which is covered by the manufacturer lifetime replacement warranty.

What limit appears first when the 6400 MHz CL52 2Rx4 kit runs sustained workloads?

The CAS latency of CL52 at 6400 MHz sets the timing boundary, while the 1.1 V registered design and dual-rank 2Rx4 organisation keep signal integrity and thermal load within the server platform specifications during continuous operation.
