  • 2 TB total capacity for memory-intensive workloads from sixteen 128 GB modules
  • DDR5 4800 speed matches the server controller for rated performance
  • Registered ECC design corrects single-bit errors and supports full population
  • 2Rx4 rank and 1.1 V voltage meet the board's exact electrical requirements
  • 288-pin RDIMM form factor fits the Supermicro H13SSH motherboard

Exact-fit DDR5 kit

This 2 TB kit contains sixteen 128 GB DDR5-4800 registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13SSH memory controller expects. Each module runs at 1.1 V with CL40 latency and a 2Rx4 organisation so the board recognises full capacity at rated speed.

Upgrade from partial or mixed populations

Replacing a smaller or mismatched set with this fully populated kit removes the instability that appears when slots run at different ranks or voltages. The jump is worth it when the workload demands the full 2 TB address space and the server must stay online without silent data corruption.

Sustained-load behaviour

Registered buffering offloads the memory controller so all sixteen slots operate together at full capacity under continuous demand. ECC corrects single-bit errors on the fly, preventing unplanned reboots that would otherwise interrupt production workloads.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H13SSH motherboard slots?

Yes, the kit is built as an exact-match upgrade for the H13SSH and uses the 288-pin Registered RDIMM form factor that board requires.

What is the correct population order when installing all 16 modules of 128 GB each?

Follow the motherboard manual's approved DIMM population sequence; the board's memory-population rules dictate which slots must be filled first for full 2 TB capacity.

Do the modules need any active cooling or heat-spreader maintenance over time?

No heat spreader is fitted and none is required; registered ECC DDR5 runs at 1.1 V and relies on standard server airflow, so only periodic dust removal is needed.
