768GB DDR5 5600 ECC RDIMM kit

This NEMIX RAM kit delivers 768GB of DDR5 5600 memory across twelve 64GB registered ECC RDIMMs. It is built for the Supermicro H13DSG-O-CPU motherboard and operates at 1.1V with CL46 latency. The 2Rx4 rank configuration matches the board's memory controller requirements for full-capacity recognition.

Upgrade from lower-capacity DDR5 RDIMMs

Replacing smaller DDR5 registered modules with this 12x64GB kit lets the H13DSG-O-CPU run all slots populated at the rated 5600 MT/s speed. The jump is worthwhile when workloads need the full 768GB addressable space and the registered architecture that keeps the memory controller stable under sustained load.

Suits Supermicro H13DSG-O-CPU deployments

This kit suits administrators populating every DIMM slot on a compatible Supermicro H13DSG-O-CPU board with validated 2Rx4 registered ECC modules. Builders using unbuffered UDIMMs, SODIMMs, or motherboards with different population rules should look at memory specified for those platforms instead.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H13DSG-O-CPU motherboard?

Yes, the kit is verified for that board and uses the 288-pin registered RDIMM form factor the motherboard requires.

What is the correct population order when installing all twelve 64 GB modules?

Follow the motherboard manual's approved DIMM population sequence; the most common mistake is skipping the prescribed slot order, which prevents full-capacity recognition.

Do the modules have heat spreaders that might need cleaning or replacement later?

No heat spreaders are included, so no spreader maintenance is required; the RDIMMs rely on server chassis airflow for cooling.
