512 GB DDR5 ECC RDIMM kit

This 512 GB kit contains four 128 GB DDR5 registered DIMMs built for Supermicro X13SET-G and X13SET-GC motherboards. It targets server and workstation administrators who need maximum registered ECC capacity in a four-module configuration.

CL40 latency at 4800 MT/s

The modules run at DDR5-4800 (PC5-38400) with a CAS latency of 40, delivering 512 GB of registered ECC headroom for virtualisation, large databases and memory-intensive compute workloads. Four ranks per module (4Rx4) increase density but limit further expansion on boards with only four slots.

1.1 V operation without heat spreaders

Each DIMM operates at 1.10 V and ships without heat spreaders, relying on chassis airflow for cooling in typical 1U or 2U server enclosures. Power draw scales with all four modules populated, so adequate case ventilation is required to maintain stable temperatures under sustained load.

Questions about this item

Will this DDR5 4800 kit run alongside any existing DDR5 modules already in my SuperMicro X13SET-G?

The kit is tested for the SuperMicro X13SET-G and X13SET-GC. Mixing with other DDR5 modules is possible but not validated; for guaranteed stability use identical 4800 CL40 4Rx4 registered ECC RDIMMs.

How can I confirm the 512 GB kit is detected and running at 4800 MT/s after installation?

Enter the system BIOS or UEFI and check the memory information screen — it should show 512 GB total, DDR5 4800 (PC5-38400), CL40 timings and registered ECC status for each of the four slots.

Does the package include only the four 128 GB RDIMMs or are any extra brackets or cables supplied?

The box contains the four 288-pin DDR5 RDIMM modules (4 × 128 GB) and nothing else; no brackets, cables or additional hardware are included.
