Exact-Match DDR5 Kit for Supermicro H13SVW-NT

This 64GB kit contains four 16GB DDR5 RDIMMs rated at 6400MT/s with CL52 latency and 1.1V operation. It is built as a direct memory upgrade for the Supermicro H13SVW-NT motherboard, matching the board's required 288-pin registered form factor and 1Rx8 rank structure.

Registered ECC Architecture for Full-Population

Registered buffering reduces electrical load on the memory controller, allowing all four slots to run at the rated 6400 speed without downclocking. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption that can crash production workloads or corrupt databases.

64GB Capacity Across Four Slots for Multi-Threaded

The four-module layout populates every channel on supported boards, giving each CPU core direct memory bandwidth for virtualization, container clusters, or in-memory analytics. Systems needing more than 64GB or a different rank configuration will require a separate kit validated for that specific motherboard.

Questions about this item

What maintenance or replacement will the 4x16GB DDR5 RDIMM kit need later?

DDR5 RDIMMs have no user-serviceable parts; the modules are solid-state and require no periodic maintenance beyond keeping the server chassis airflow clear.

What limit shows up first when the 6400 CL52 registered DIMMs run fully populated all day?

The memory controller on the Supermicro H13SVW-NT board sets the maximum supported capacity and population rules; consult the board manual for the exact ceiling.

How much heat or power do the 1.1V 288-pin ECC modules add during continuous operation?

Each 16GB 1Rx8 module operates at 1.10V, so the kit draws minimal power and produces little heat compared to higher-voltage DDR5; ensure standard server cooling.
