Exact-Match DDR5 ECC RDIMM Kit

This 384 GB kit contains six 64 GB DDR5 4800 registered ECC RDIMMs built to the specifications of the Supermicro H13SVW-NT-OS2 motherboard. It is intended for administrators who need to populate every slot with validated modules that run at rated speed and capacity.

Verify Population Rules First

Check your motherboard manual for the approved DIMM population order, maximum supported capacity per channel, and any BIOS version requirements before ordering. The registered architecture and 2Rx4 rank layout must match the platform's memory controller expectations for full recognition.

Replaces Smaller or Unvalidated Kits

The jump is worth it when your current configuration cannot reach the desired capacity or mixes modules that force the controller to downclock. This kit eliminates population guesswork and provides ECC protection across the full 384 GB address space.
