Exact DDR5-6400 upgrade for Supermicro H13SRH

This 64GB NEMIX RAM module is a 288-pin DDR5 RDIMM rated at 6400 MT/s with CL52 latency and 1.1V operation. It uses a 2Rx4 registered ECC design built on major OEM DRAM chips. The specification matches the memory controller requirements of the Supermicro H13SRH motherboard so the system recognises the full capacity and runs at the rated speed without manual tuning.

Suited for administrators expanding a Supermicro

The registered ECC architecture supports fully populated slots while correcting single-bit errors to protect data integrity. Buyers who need unbuffered UDIMMs, SODIMMs, non-ECC memory, or a different voltage, rank, or speed should look elsewhere because this module will not fit or function in those configurations.

The registered ECC RDIMM form factor decides fit

The Supermicro H13SRH requires 288-pin registered DIMMs; this module meets that requirement exactly. A UDIMM or SODIMM will not seat in the board's slots, and a non-ECC or unbuffered DIMM will not satisfy the platform's memory population rules.

Questions about this item

Will the 2Rx4 registered ECC DDR5 RDIMM require any periodic maintenance or component replacement during its service life?

No, the module has no moving parts or heat spreader and is designed to operate continuously without scheduled maintenance or user-replaceable components.

What limit appears first when the 64 GB DDR5 6400 CL52 module runs at full load for extended periods?

The CAS latency of CL52 and the fixed 1.10 V operating voltage set the timing and power boundaries that the memory controller enforces under sustained use.

How much heat and power does the 288-pin 64 GB DDR5 RDIMM generate when it runs all day in a Supermicro H13SRH server?

Operating at 1.10 V with no heat spreader, the module relies on chassis airflow to dissipate the modest heat produced by its registered ECC design during continuous operation.
