768GB DDR5 ECC RDIMM kit

This 768GB kit contains six 128GB DDR5 6400MHz CL52 registered ECC modules. It is built for the Supermicro Hyper SuperServer SYS-222HA-TN and other platforms that accept 288-pin DDR5 RDIMMs. The 2Rx4 organisation and 1.1V operation suit enterprise workloads that require error correction and high density.

Verify DDR5 RDIMM slot count and population rules

Confirm your motherboard provides at least six DDR5 RDIMM slots and supports 128GB 2Rx4 modules at 6400MHz. Check the vendor memory-qualified list for this exact part number and ensure the BIOS is updated to recognise the full 768GB capacity. Registered ECC modules will not function in consumer boards that only accept unbuffered memory.

Kit delivers matched six-module population

The six matched modules allow full-channel population without mixing capacities or ranks. No heat spreaders are included, so airflow across the modules must be provided by the server chassis. The package contains only the memory kit; no additional software, cables or mounting hardware are supplied.

Questions about this item

Does the kit include anything besides the six 128GB modules?

The package contains only the six 128GB DDR5 6400MHz CL52 ECC RDIMM modules; no heat spreaders, cables or tools are supplied.

When should I choose the 6x128GB 768GB kit instead of a smaller capacity?

Select this kit when the Supermicro SYS-222HA-TN has six available DDR5 slots and the workload requires the full 768GB registered ECC capacity.

What does the 6400MHz rating deliver once installed in the SYS-222HA-TN?

The modules run at DDR5 6400MHz PC5-51200 with CL52 latency at 1.1V, providing registered ECC bandwidth for the supported Supermicro server platform.
