  • 512GB total capacity from four 128GB modules maximizes server memory density
  • DDR5-6400 speed with CL52 latency delivers rated bandwidth for compute workloads
  • Registered ECC architecture offloads the controller and corrects single-bit errors
  • 1V operation matches the platform voltage spec for stable full-population runs
  • Verified fitment for Supermicro X14SDV-36C-SP3F motherboard with 288-pin RDIMM slots

Exact-match DDR5 ECC RDIMM kit

This 512GB kit contains four 128GB DDR5 6400 RDIMMs rated at CL52 and 1.1V. Each module is a 4Rx4 registered ECC part built with major OEM chips. The 288-pin form factor matches the Supermicro X14SDV-36C-SP3F motherboard memory slots exactly.

Suited for fully populating that board

Administrators expanding a Supermicro X14SDV-36C-SP3F to its maximum supported capacity with registered ECC modules will find the correct rank, voltage and timing pre-validated. Builders needing unbuffered UDIMMs, SODIMMs, lower densities or non-ECC memory should look elsewhere.

Verify population rules before ordering

Consult the motherboard manual for approved DIMM population order, maximum capacity per slot and any BIOS version requirements. Confirm the server chassis can accommodate four 288-pin RDIMMs and that the memory controller supports 4Rx4 registered modules at the rated speed.

Questions about this item

Do I need a Supermicro X14SDV-36C-SP3F motherboard with free 288-pin DDR5 RDIMM slots to use this 512GB kit?

Yes, this kit is validated for the Supermicro X14SDV-36C-SP3F motherboard and requires four available 288-pin DDR5 RDIMM slots running at 1.1V to operate as specified.

Will these 4Rx4 registered ECC modules work alongside any existing DDR5 RDIMMs already installed in the board?

Mixing ranks or capacities can change the memory controller's population rules; the board manual should be consulted to confirm supported mixed-configuration layouts before adding this 4Rx4 kit.

How can I verify the kit is running at DDR5 6400 CL52 with ECC active after installation?

Enter the BIOS or UEFI and confirm the memory frequency reads 6400 MT/s, CAS latency shows CL52, and ECC status reports enabled for all 512GB.
