Speed 4800MHz

  • 512 GB total capacity in a matched 4 × 128 GB kit for full server population
  • DDR5 4800 MHz speed with CL40 latency delivers rated throughput for Supermicro H13SVW-NT
  • Registered ECC architecture offloads the memory controller and corrects single-bit errors on the fly
  • 10 V operation at 2Rx4 rank matches the board's exact voltage and timing requirements
  • 288-pin RDIMM form factor fits the Supermicro H13SVW-NT motherboard without adapters

Exact-fit 512GB DDR5 kit

This 512GB kit delivers four 128GB DDR5 4800 Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H13SVW-NT memory controller expects. It is intended for administrators expanding a single server to its maximum supported capacity with modules that post at full speed on first boot.

Rank and voltage alignment

The 2Rx4 organisation and 1.10V operating point match the board's population rules so every slot can be filled without down-clocking or training failures. Registered buffering offloads the controller while ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads.

288-pin RDIMM form factor

Modules use the standard 288-pin Registered DIMM edge connector required by the H13SVW-NT, not UDIMM or SODIMM alternatives. No heat spreaders are fitted, ensuring clearance in dense multi-socket chassis where airflow is managed by the system fans.

Questions about this item

Will the 128 GB RDIMMs need any firmware updates or periodic reseating after installation?

No firmware updates or scheduled reseating are required; the registered DDR5 modules are validated for continuous operation in the Supermicro H13SVW-NT once seated correctly.

What thermal or power limit appears first when all four slots run at 4800 MHz continuously?

Each module draws 1.1 V at the rated 4800 MHz speed, so the platform's memory-controller power budget is the first constraint under full sustained load.

How much fan noise or case heat should I expect from the kit running 24/7 without heat spreaders?

Bare DRAM at 1.1 V produces minimal heat; typical server chassis airflow keeps temperatures well within spec with no audible increase over baseline fan speeds.
