384GB DDR5 ECC RDIMM kit for Supermicro H13SST-GC

This 384GB kit contains twelve 32GB DDR5 4800 registered ECC modules built to the exact rank, voltage and timing the Supermicro H13SST-GC memory controller expects. It targets administrators who need maximum supported capacity in every slot for virtualisation hosts, database servers or compute clusters.

Verify DIMM population rules

Consult the Supermicro H13SST-GC manual for approved population order, maximum capacity per channel and any BIOS version requirements. The board requires 288-pin registered RDIMMs; unbuffered UDIMMs or SODIMMs will not function. Confirm that your configuration supports twelve 2Rx8 modules at the rated voltage.

Registered architecture maintains stability under

The registered buffer reduces electrical load on the memory controller so all twelve slots can run fully populated at the rated 4800 MT/s without down-clocking. ECC corrects single-bit errors in real time, preventing silent data corruption during sustained workloads such as large in-memory databases or long-running render jobs.

Questions about this item

What comes in the box and do I need to buy anything else to install this kit?

The kit contains twelve 32 GB DDR5 4800 CL40 1.1 V 2Rx8 ECC registered RDIMM modules for a total of 384 GB. No extra parts are required for installation.

How do I decide between the 384 GB kit and a smaller capacity for my Supermicro H13SST-GC?

Choose this 384 GB kit when your workload needs the maximum supported memory and you can populate all twelve slots with 2Rx8 registered ECC modules.

What does the DDR5 4800 CL40 rating mean once the modules are running in the server?

The modules operate at 4800 MT/s with a CAS latency of 40 cycles at 1.1 V, delivering the rated bandwidth and error-correction the motherboard expects when fully populated.
