Exact-match DDR5 kit for Supermicro H14DSH

This 128GB kit contains four 32GB DDR5-6400 registered ECC RDIMMs built to the precise rank, voltage and timing the motherboard expects. Each module runs at 1.1V with CL52 latency and a 2Rx8 organisation so the memory controller recognises the full capacity at rated speed.

Installation follows standard RDIMM procedure

Insert the 288-pin modules into the slots specified by the Supermicro H14DSH manual in the approved population order. The registered architecture offloads the memory controller allowing full population, while ECC corrects single-bit errors on the fly. Verify the board's supported capacities and population rules before starting.

Suited for administrators upgrading a Supermicro

This kit serves environments that require registered ECC memory at DDR5-6400 with 1.1V operation and 2Rx8 density. It is not for systems that accept only unbuffered UDIMMs, SODIMM form factors, different DDR generations, lower capacities, or non-ECC configurations.

Questions about this item

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

Enter the BIOS or use a tool like CPU-Z and confirm each module shows 6400 MT/s, CL52 timings, 1.10 V, and 2Rx8 registered ECC operation.

What does the package contain and is anything else required?

The box includes four 32 GB DDR5 288-pin RDIMM modules for a total of 128 GB; no extra parts are needed if your Supermicro H14DSH has four free DIMM slots.

Should I choose a different capacity or speed for this motherboard?

This 128 GB kit matches the exact DDR5 6400 CL52 1.10 V 2Rx8 registered specification the H14DSH expects, so select this version for guaranteed compatibility.
