Capacity and compatibility

This 576GB kit contains six 96GB DDR5 ECC RDIMM modules built for the SuperMicro GPU SuperServer SYS-422GS-NBRT-LCC. Registered buffering and 2Rx4 organisation suit multi-socket server workloads that demand large memory footprints. The kit targets administrators expanding capacity on this specific platform.

Registered ECC operation

Registered signalling reduces electrical load on the memory controller, allowing all six modules to run at 6400MHz with CL52 latency. On-die ECC corrects single-bit errors and detects multi-bit faults, protecting data integrity in continuous compute tasks. The 1.1V operating voltage matches the DDR5 baseline for this module class.

Platform verification

Confirm the SuperServer SYS-422GS-NBRT-LCC motherboard accepts 96GB RDIMMs at 6400MHz and supports 2Rx4 density across all populated slots. Check the vendor memory-qualified list for the exact part number MR51200-9624K6 and verify BIOS revision requirements. Systems needing unbuffered DIMMs or lower-density ranks cannot use this kit.

Questions about this item

Will the 1.10V operating voltage of these DDR5 ECC RDIMMs change over the kit's lifespan?

The modules run at a fixed 1.10V; DDR5 voltage regulation is handled on the DIMM itself, so no external adjustment is needed as the hardware ages.

At 6400MHz and CL52, does the CAS latency become the first bottleneck during sustained server workloads?

With a CL52 timing at 6400MHz, the latency window is the primary limit you will hit before bandwidth saturates in typical multi-threaded server tasks.

How much heat do six 96GB registered DIMMs produce when the SuperMicro SYS-422GS-NBRT-LCC runs continuously?

Six 2Rx4 RDIMMs at 1.1V draw modest power; the kit has no heat spreaders, so adequate chassis airflow across the 288-pin slots is the only cooling requirement.
