  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Rated voltage1.1 V
  • Buffer typeRegistered

Size 512GB 4X128GB

  • 512 GB capacity across four 128 GB modules for maximum server density
  • DDR5 5600 speed with CL46 latency matches the motherboard's rated timing
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation meets the board's voltage spec for reliable operation
  • 288-pin RDIMM form factor fits the Supermicro X14SDV-36C-SP3F memory slots

Targeted server upgrade

This 512 GB kit delivers four 128 GB DDR5 RDIMMs built for the Supermicro X14SDV-36C-SP3F motherboard. It targets administrators who need maximum registered ECC capacity on this specific platform without mixing module densities.

Capacity and headroom

The 4Rx4 organization and 1.10 V operation let all four slots run at the rated 5600 MT/s CL46, giving the full 512 GB the board can address. Population rules or BIOS limits on this platform may restrict larger configurations, so the manual should be checked before ordering.

Build integration

Modules use the 288-pin RDIMM form factor this motherboard requires, not UDIMM or SODIMM. Registered buffering reduces electrical load on the memory controller when fully populated, and on-die ECC corrects single-bit errors in flight. No heat spreaders are fitted, so chassis airflow must handle thermal management.

Questions about this item

Will this 512GB DDR5 5600 4Rx4 kit run alongside any existing RDIMMs in my Supermicro X14SDV-36C-SP3F?

The kit is an exact-match upgrade for the Supermicro X14SDV-36C-SP3F. Mixing ranks or speeds can prevent full-capacity recognition, so populate all four slots with this 4x128GB set for guaranteed DDR5-5600 operation.

How do I verify the kit is running at DDR5-5600 CL46 1.1V after installation?

Enter the server BIOS or UEFI and confirm the memory frequency reads 5600 MT/s, CAS latency shows 46, and voltage reports 1.1V with all four 128GB modules detected as registered ECC.

What comes in the box and do I need any extra brackets or cables?

The package contains four 128GB 288-pin DDR5 RDIMM modules only. No heat spreaders, brackets, cables or additional hardware are included or required for installation.
