  • Exact 128 GB (8×16 GB) DDR5-5600 kit matches the Supermicro H14DSG-OD memory controller for full-capacity operation
  • Registered ECC RDIMM architecture offloads the controller and corrects single-bit errors to prevent silent data corruption
  • 1Rx8 organisation at 1.1 V CL46 delivers the precise rank, voltage and timing the board expects
  • 288-pin RDIMM form factor is the only module type the H14DSG-OD accepts — no UDIMM or SODIMM fit
  • Lifetime replacement warranty with free US-based technical support backs every module in the kit

Exact-match DDR5-5600 ECC RDIMM kit

This 128GB kit contains eight 16GB DDR5-5600 Registered ECC RDIMMs built to the precise 1Rx8 rank, 1.1V voltage and CL46 timing the Supermicro H14DSG-OD memory controller expects. The 288-pin modules install directly into the server board without adapters.

Suited for full-population server upgrades

It fits administrators populating every DIMM slot on a compatible Supermicro H14DSG-OD platform who need registered ECC stability at the board's rated 5600 MT/s speed. Builders using unbuffered UDIMMs, SODIMM form factors, or non-ECC memory should look elsewhere because those types will not be recognised by this registered-DIMM-only controller.

Straightforward slot-in installation

Align the 288-pin edge connector with the keyed RDIMM socket and press until the retention clips lock; no tools or firmware flashes are required. The most common issue is ignoring the motherboard manual's population order, which can leave capacity unrecognised or force the system to run at a lower speed.

Questions about this item

What motherboard must I already have for this 128GB DDR5 5600 kit to be recognized at full capacity?

The kit is spec-matched for the Supermicro H14DSG-OD motherboard and its 288-pin RDIMM slots, so the board will recognize all 128GB at the rated 5600 speed.

Can I keep any existing DDR5 RDIMMs in the H14DSG-OD while adding this 8x16GB CL46 kit?

The board's memory-population rules decide whether mixed ranks or speeds are allowed; consult the motherboard manual for the approved DIMM order before mixing modules.

How do I confirm the kit is running at DDR5 5600 with CL46 and ECC active after installation?

Enter the BIOS or use a tool like dmidecode to verify the reported speed is 5600 MT/s, CAS latency is 46, voltage reads 1.1V, and ECC status shows enabled.
