Exact-match 768GB kit for Supermicro H13SST-GC

This NEMIX RAM kit delivers 768GB of DDR5 memory across eight 96GB registered DIMMs. It is built for the Supermicro H13SST-GC motherboard and matches the board's required 288-pin RDIMM form factor, voltage and timing profile.

Registered ECC architecture with CL52 timing

The 2Rx4 registered design buffers address and command signals so the memory controller can drive every slot at full population. On-die ECC detects and corrects single-bit errors in flight, preventing silent data corruption in production workloads.

1.1V operation and 288-pin RDIMM connectors

Modules run at the standard 1.10V DDR5 voltage and plug directly into the board's 288-pin slots without adapters. Buyers who need a different capacity, a UDIMM form factor or non-ECC memory should look elsewhere.

Questions about this item

Will the 96GB modules need individual replacement if one fails?

The kit is sold as an 8-module matched set; a single module failure typically means replacing that one DIMM, but the remaining seven stay in service because they are not paired in a way that requires a full-kit swap.

What limits sustained throughput first on this 768GB kit?

The memory controller on the Supermicro H13SST-GC motherboard sets the practical ceiling; the modules run at DDR5 6400 with CL52 latency, so the board's maximum supported speed and population rules become the bottleneck before the DIMMs themselves.

How much extra heat does the registered ECC design add during all-day operation?

Registered RDIMMs add a small buffer chip per module, and the 1.10V operating voltage keeps power draw modest; with no heat spreaders fitted, airflow across the 288-pin slots is the main factor for temperature control.
