Exact-match DDR5 upgrade for Supermicro H13SST-G

This 32 GB kit contains two 16 GB DDR5 6400 modules built to the PC5-51200 standard. Each DIMM is a 288-pin registered ECC RDIMM with 1Rx8 organisation, CL52 latency and 1.10 V operation. The specification matches the memory controller requirements of the Supermicro H13SST-G motherboard so the full capacity is recognised at rated speed.

Sustained-load stability with registered ECC

Registered buffering offloads the memory controller, allowing every populated slot to run at full capacity without signal degradation. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during continuous server workloads. The 1.10 V operating voltage keeps power draw consistent across long duty cycles.

Verify population rules before ordering

Server memory support varies by model and BIOS revision; consult the motherboard manual for approved DIMM population order, maximum supported capacity per channel and any required firmware updates. The kit uses the 288-pin RDIMM form factor and will not fit UDIMM or SODIMM slots. No heat spreader is included, so confirm airflow meets your chassis design.
