  • DDR5-5600 speed with CL46 latency matching the motherboard's rated timing
  • 1 V operation reduces power draw while maintaining registered ECC stability
  • 2Rx8 registered ECC design corrects single-bit errors under full population
  • 288-pin RDIMM form factor verified for Supermicro H13SST-GC motherboard

Exact-match upgrade kit

This 64GB kit contains two 32GB DDR5-5600 registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13SST-GC memory controller expects. The modules are recognised at full capacity and run at their rated speed without manual tuning.

Registered ECC stability

Registered architecture offloads the memory controller so every slot operates fully populated at full capacity, while ECC catches and corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. Builders who need unbuffered UDIMMs or non-ECC modules cannot use this kit.

DDR5-5600 interface limits

The DDR5 interface tops out at 5600 MT/s with CL46 latency at 1.1V, so bandwidth and response time are fixed by the standard and the motherboard's memory controller. Systems that require higher data rates, lower latency or a different voltage must use a platform that supports faster DDR5 specifications.

Questions about this item

Will the 2Rx8 registered ECC modules need any firmware updates or periodic reseating to stay stable in the Supermicro H13SST-GC?

The modules are an exact-match DDR5-5600 kit with 1.10 V, CL46 timings and registered ECC; no firmware updates or scheduled reseating are required once they are seated in the approved DIMM slots.

What thermal or power ceiling appears first when the 64 GB kit runs at DDR5-5600 continuously?

Each DIMM operates at the standard 1.10 V DDR5 voltage with no heat spreader, so the platform's memory-controller thermal limit will be reached before the modules exceed their rated power envelope.

How much fan noise or extra heat should I expect from the two 32 GB RDIMMs during all-day operation?

The registered ECC DDR5-5600 modules draw only 1.10 V and have no onboard heat spreader, so they add minimal heat and require no additional cooling beyond the server's standard airflow.
