384GB DDR5 6400 ECC RDIMM Kit

This 384GB kit contains six 64GB DDR5 6400 registered ECC RDIMMs. The modules run at 1.1V with CL52 latency and a 2Rx4 rank structure. They are built to the exact specification the Supermicro H14DSG-O-CPU motherboard expects.

Who This Kit Suits

It suits administrators upgrading a Supermicro H14DSG-O-CPU server that requires registered ECC DDR5 at 6400 MT/s in a six-module population. It does not suit systems that need unbuffered UDIMMs, SODIMM form factors, non-ECC memory, or speeds other than DDR5 6400.

Deciding Specification

The motherboard must accept 288-pin registered DDR5 RDIMMs at 6400 MT/s with 2Rx4 organisation and 1.1V operation. If the board's qualified-vendor list calls for a different rank, voltage, or speed, these modules will not be recognised at full capacity.

Questions about this item

Does the kit include all six 64 GB modules or do I need to buy any DIMMs separately?

The package contains the full 384 GB kit with six 64 GB DDR5 6400 CL52 2Rx4 ECC RDIMMs, so no additional modules are required.

Should I choose a different capacity kit or is this 384 GB 6 x 64 GB version the right match for the Supermicro H14DSG-O-CPU?

This exact 384 GB kit (6 x 64 GB) is spec-matched to the H14DSG-O-CPU motherboard's population rules and registered ECC requirements.

What does the 6400 MT/s rating mean once the memory is installed in the server?

The modules run at DDR5-6400 (PC5-51200) with CL52 latency at 1.1 V, delivering the rated throughput the board's memory controller expects.
