64GB DDR5-4800 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5-4800 (PC5-38400) registered ECC modules built to the 288-pin RDIMM form factor. It is designed for the Supermicro H14SST-G motherboard where registered memory is required for full-capacity operation.

Upgrade from non-ECC or UDIMM memory

Replacing unbuffered or non-ECC modules with this registered ECC kit enables the memory controller to address every populated slot at the rated 4800 MT/s speed while adding single-bit error correction. The jump is worth it when your workload demands data integrity and the board's population rules call for 2Rx8 registered DIMMs at 1.1V.

Suits Supermicro H14SST-G server builds

This kit suits administrators populating a Supermicro H14SST-G with validated 64GB of registered ECC DDR5. Builders needing unbuffered UDIMMs, SODIMM form factors, speeds other than DDR5-4800, or capacities beyond this 2x32GB configuration should look at something else.

Questions about this item

Does the 288-pin RDIMM form factor fit the Supermicro H14SST-G motherboard slots?

Yes, the 288-pin Registered DIMM form factor matches the DDR5 slots required by the Supermicro H14SST-G motherboard.

What is the correct population order for the two 32GB modules on the Supermicro H14SST-G?

Consult the motherboard manual for the approved DIMM population sequence; the kit must be installed in the specific slot order the board defines for dual-channel operation.

Will the ECC and registered features require any special configuration after installation?

ECC error correction and registered buffering operate automatically once the modules are recognised by the memory controller; no extra software setup is needed.
