  • DDR5 5600 speed (PC5-44800) delivers rated bandwidth on Supermicro H13SST-GC
  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically
  • 1 V operation at CL46 matches the motherboard's voltage and timing requirements
  • 288-pin RDIMM form factor fits the board's memory slots and population rules

Exact-Match Server Upgrade

This NEMIX RAM kit provides 384GB across six 64GB DDR5 5600 PC5-44800 registered ECC RDIMMs. It is built for administrators upgrading a Supermicro H13SST-GC motherboard to its full supported capacity with modules that match the board's required rank, voltage and timing.

DDR5 Registered Interface Limits

DDR5 5600 RDIMMs operate at 1.1V with a CL46 latency and 2Rx4 organisation. The registered buffer reduces electrical load on the memory controller, allowing all slots to run fully populated at the rated 5600MT/s speed. ECC corrects single-bit errors but the interface does not support unbuffered or SODIMM form factors.

Installation Guidance

Each 288-pin module keys into the board's DDR5 RDIMM slots in the order specified by the Supermicro manual. Population rules for six DIMMs must be followed exactly or the system will not recognise the full 384GB. No heat spreaders are fitted so airflow across the chips must be maintained by the chassis fans.

Questions about this item

Should I choose the 384 GB kit or a smaller capacity for my Supermicro H13SST-GC?

The 384 GB kit provides six 64 GB modules that fill the board's slots for maximum registered ECC capacity. Choose it when your workloads need the full 384 GB; otherwise select a smaller kit that matches your actual memory requirement.

What does the 5600 MT/s speed mean once the modules are installed in the server?

The DDR5-5600 rating means each module transfers data at 5600 million transfers per second, delivering PC5-44800 bandwidth when the memory controller runs them at the rated CL46 latency and 1.1 V.

How does the 288-pin RDIMM interface limit performance in this platform?

The 288-pin registered DIMM interface is required by the Supermicro H13SST-GC; it caps the memory to DDR5-5600 operation with ECC and registered buffering, preventing use of faster or unbuffered module types.
