Speed 5600MHz

  • 128 GB module runs at full DDR5-5600 speed with CL46 latency
  • Registered ECC design corrects single-bit errors to prevent silent data corruption
  • 1 V operation matches the server memory controller's exact voltage requirement
  • 2Rx4 288-pin RDIMM form factor fits Supermicro H13SVW-NT population rules
  • Major OEM Samsung, Micron or Hynix chips deliver enterprise-grade stability

Exact-match DDR5 RDIMM for Supermicro H13SVW-NT

This 128GB DDR5 5600 registered ECC module delivers the precise 2Rx4 rank structure, 1.1V operating voltage and CL46 timing the motherboard's memory controller expects. It installs as a single 288-pin RDIMM so the server recognises the full capacity at rated speed without manual configuration.

Upgrade from lower-capacity or mixed-rank kits

Replacing smaller RDIMMs or mismatched ranks with this spec-matched module removes population-rule conflicts and lets every slot run fully populated at 5600 MT/s. The jump is worth it when your workload needs maximum registered memory bandwidth and ECC integrity across all channels.

128GB per module headroom

A single stick provides 128GB of registered ECC capacity, giving ample room for virtualisation hosts, database buffers and large-scale compute jobs. Headroom ends when the platform's maximum supported memory per socket or total slot count is reached, so consult the board manual for the final limit.

Questions about this item

Will this 288-pin RDIMM fit the DIMM slots on my Supermicro H13SVW-NT motherboard?

Yes, the module uses the 288-pin DDR5 RDIMM form factor that the H13SVW-NT requires, so it seats directly in the server's registered DIMM slots without adapters.

What is the correct population order when installing this 2Rx4 registered ECC module?

Follow the motherboard manual's approved DIMM population sequence; the board's memory controller expects registered ECC modules in a specific slot order to initialise at the rated 5600 MT/s speed.

Does this DDR5 ECC RDIMM require any firmware updates or periodic maintenance after installation?

No firmware updates are needed for the memory itself; ECC error correction runs automatically, and the module has no heat spreader or moving parts that would require scheduled servicing.
