Targeted Server Upgrade

This 512GB kit delivers four 128GB DDR5 6400 Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H13SVW-N memory controller expects. It is intended for administrators who need maximum capacity in every slot without mixing modules.

Thermals and Power

Each module operates at 1.1V with no heat spreader, relying on the server's directed airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping power draw predictable even with all four slots populated.

Registered ECC Requirement

The motherboard requires 288-pin Registered (RDIMM) DDR5 with ECC; UDIMM or non-ECC modules will not function. Verify your system manual for supported population rules and maximum capacity per channel before ordering.

Highlights

  • 512 GB total capacity from four 128 GB modules
  • DDR5 6400 speed with CL52 latency for rated performance
  • Registered ECC design prevents silent data corruption
  • 1 V operation matches server memory controller requirements
  • Verified fit for Supermicro H13SVW-N motherboard

Questions about this item

How do I install the 288-pin RDIMM modules in the Supermicro H13SVW-N, and what step is often missed?

Power down and unplug the server, then open the chassis. Insert each 128 GB module into the slots specified by the motherboard manual, pressing until the latches click. The step people skip is verifying the exact population order for a 4 x 128 GB configuration.

What maintenance or replacement will the 512 GB DDR5 ECC RDIMM kit need over its service life?

No scheduled maintenance is required for the modules themselves. Keep the server's air filters clean and firmware current so the registered ECC memory operates within its 1.10 V spec. Replace a module only if the system logs uncorrectable ECC errors.

What limit appears first when the 6400 MHz CL52 kit runs fully populated under sustained load?

The registered 2Rx4 architecture is designed to let all four slots run at the rated 6400 MT/s without downclocking. The first practical limit is the server's thermal envelope; if chassis airflow is insufficient, the memory controller may throttle speed to protect stability.
