Exact-match DDR5-6400 kit for Supermicro H14DSG-OD

This 64GB kit contains four 16GB DDR5-6400 registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H14DSG-OD memory controller expects. It is intended for administrators who need the full 64GB recognised at rated speed without manual tuning.

288-pin registered form factor with ECC

Each module uses the 288-pin RDIMM form factor this board requires, not a UDIMM or SODIMM. Registered architecture offloads the memory controller so every slot runs fully populated at full capacity, while ECC catches and corrects single-bit errors on the fly to stop silent data corruption and unplanned reboots before they reach production.

Four-module kit with lifetime support

The package delivers the complete 4x16GB configuration in one matched set, removing the risk of mixing incompatible sticks. Buyers who need a different total capacity or a non-ECC unbuffered kit for a workstation should look elsewhere.

Questions about this item

What DDR5 speed and CAS latency does this 64GB kit run at?

This kit operates at DDR5-6400 (PC5-51200) with a CL52 latency, the exact timing the Supermicro H14DSG-OD memory controller expects for full-speed operation.

Will these 288-pin RDIMMs physically fit the H14DSG-OD DIMM slots?

Yes, the modules are 288-pin Registered DDR5 RDIMMs, the precise form factor the H14DSG-OD requires; they are not UDIMMs or SODIMMs.

How should I populate the four 16GB modules on the H14DSG-OD, and what step is commonly missed?

Install all four 1Rx8 RDIMMs following the motherboard manual's approved population order, then verify in BIOS that the full 64GB is recognised at DDR5-6400 — skipping the population-order check is the step most often missed.
