Server DDR5 ECC RDIMM Kit

This 384GB kit contains twelve 32GB DDR5 6400 RDIMMs with CL52 latency and 1.1V operation. It is built for Supermicro H13SSW motherboards that require registered ECC memory in a 288-pin form factor. The 2Rx8 organization matches the board's memory controller expectations for full-capacity recognition.

Motherboard Population Rules

Verify the H13SSW manual for supported capacities per channel and the approved DIMM installation order before ordering. The board requires registered RDIMMs, not unbuffered UDIMMs or SODIMMs, and population rules change with the number of modules installed. Confirm your CPU and BIOS revision support the full 384GB configuration at DDR5 6400 speed.

Enterprise Stability Features

Registered buffering reduces electrical load on the memory controller when all twelve slots are populated, while on-die ECC corrects single-bit errors without halting the system. These mechanisms protect data integrity in continuous production workloads. The modules ship without heat spreaders, so chassis airflow must meet the server vendor's thermal requirements.

Questions about this item

What comes in the 12-module kit and is anything else required to install it?

The kit contains twelve 32 GB DDR5 6400 CL52 2Rx8 1.10 V 288-pin ECC Registered RDIMM modules for a total of 384 GB; no additional parts are needed for installation in a compatible server.

How do I decide between this 384 GB kit and a smaller capacity for my Supermicro H13SSW?

Choose this 384 GB kit when your workload needs the maximum supported memory and the motherboard manual confirms all twelve slots can be populated with 2Rx8 Registered DIMMs at DDR5 6400.

What does the DDR5 6400 CL52 rating deliver once the modules are running in the server?

The modules operate at 6400 MT/s with a CAS latency of 52 cycles at 1.10 V, providing the exact speed and timing the H13SSW memory controller expects for full-capacity, error-corrected operation.
