NEMIX RAM DDR5 512GB 16x32GB 6400MHz CL52 1.1V 2Rx8 ECC RDIMM Supermicro H13DSH

Exact-match upgrade for Supermicro H13DSH

This 512 GB kit contains 16 registered DDR5 ECC RDIMM modules at 32 GB each. The 2Rx8 organisation, 1.10 V operation and CL52 timing match the H13DSH memory controller specification so the system recognises full capacity at DDR5-6400 speed. It is intended for administrators who need maximum supported memory on this platform. Builders using other motherboards or unbuffered DIMM slots cannot use this kit.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller, allowing all 16 slots to remain populated at the rated 6400 MT/s data rate during continuous workloads. On-die ECC corrects single-bit errors in real time, preventing silent data corruption that would otherwise accumulate under heavy utilisation. The modules maintain their specified CL52 latency without downclocking when the server runs at full capacity for extended periods.

Thermals and power

Operating at 1.10 V keeps per-module power draw low even with every slot filled, helping the chassis cooling subsystem maintain stable inlet temperatures. No heat spreaders are fitted, so airflow across the bare DRAM packages is the primary cooling path; the server's standard fan profile is sufficient for normal operation. Acoustic output remains unchanged from the baseline platform configuration.
