Exact-Match DDR5 Upgrade

This 48GB DDR5-6400 registered ECC RDIMM is built for the Supermicro H13SVW-NT motherboard. It delivers the precise rank, voltage, and timing the memory controller expects so the module is recognised at full capacity and runs at its rated speed without manual tuning.

Build Integration

The 288-pin registered form factor matches the board's slot requirements and population rules, offloading the memory controller to allow every slot to run fully populated at full capacity. No heat spreader is fitted, so the module fits in dense server chassis where taller DIMMs would interfere with airflow or neighbouring components.

Sustained Operation

ECC circuitry catches and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during continuous workloads. Registered buffering stabilises the signal across all populated slots, maintaining consistent throughput and reliability under prolonged load.

Questions about this item

How does the 1.10V operating voltage affect sustained thermal load in a fully populated Supermicro H13SVW-NT?

The 1.10V DDR5 standard voltage keeps per-module power draw low, so even with every slot filled the registered DIMMs add minimal heat to the chassis airflow path.

What acoustic impact should I expect when this 48GB RDIMM runs continuously in a dense server rack?

The module has no heat spreader or moving parts, so it adds zero noise; only the system fans respond to the slight extra thermal load from the 2Rx8 registered chips.

Which motherboard feature must already be present for this 288-pin ECC RDIMM to function at 6400 MT/s?

The Supermicro H13SVW-NT must provide a DDR5 RDIMM slot with registered-buffer support and ECC enabled in the BIOS for the kit to operate at its rated speed.
