  • 512 GB total capacity from four 128 GB modules for maximum server density
  • DDR5 5600 speed with CL46 latency delivers rated throughput on supported platforms
  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically
  • 10 V operation matches the motherboard specification for stable full-population performance
  • Exact-fit 288-pin RDIMM kit validated for Supermicro H14DSG-OD memory population rules

Exact-match DDR5 ECC RDIMM kit

This 512 GB kit contains four 128 GB DDR5-5600 registered ECC modules built to the PC5-44800 standard. Each 288-pin RDIMM runs at 1.10 V with CL46 latency and a 2Rx4 rank layout. The registered design offloads the memory controller so all four slots can be populated at full rated speed on the Supermicro H14DSG-OD motherboard.

Verify motherboard population rules

Check the Supermicro H14DSG-OD manual for approved DIMM population order and maximum supported capacity per channel before ordering. Confirm that your system requires registered DDR5 RDIMMs rather than unbuffered UDIMMs or SODIMMs. Ensure the BIOS is updated to a version that recognises 128 GB dual-rank modules at DDR5-5600.

Suited for fully populated server builds

Ideal for administrators expanding a Supermicro H14DSG-OD platform to its maximum supported memory with ECC protection against silent data corruption. Not suitable for workstations or desktops that accept only unbuffered memory, nor for systems limited to lower-density modules or slower DDR5 speeds. Buyers needing non-ECC or UDIMM form factors should look elsewhere.

Questions about this item

What is included in the NEMIX RAM 512GB kit and is any additional hardware needed for installation?

The kit contains four 128GB DDR5 5600 CL46 ECC registered RDIMMs. No extra hardware is required; the modules plug directly into the 288-pin DIMM slots on the Supermicro H14DSG-OD motherboard.

Why choose the 512GB 4x128GB DDR5-5600 CL46 kit instead of a smaller capacity or different speed?

This exact-match kit provides the full 512GB capacity the board supports with four 2Rx4 registered modules at the rated 5600 MT/s speed and 1.1V voltage, ensuring the memory controller recognises every slot at its specified timing.

What does the DDR5-5600 (PC5-44800) rating mean for real-world server performance?

The modules run at 5600 MT/s with CL46 latency at 1.1V, delivering the bandwidth and error-correcting stability the H14DSG-OD platform expects when fully populated with registered ECC memory.
