256GB DDR5-6400 ECC RDIMM kit

This 256GB kit contains sixteen 16GB DDR5-6400 Registered ECC modules built for the Supermicro H14DST-F motherboard. Each DIMM runs at 1.1V with CL52 latency and a 1Rx8 organisation. The registered design lets the board run fully populated without overloading the memory controller.

Verify motherboard population rules

Check the Supermicro H14DST-F manual for approved DIMM population order, maximum supported capacity per slot and any BIOS version requirements before installing. The board requires 288-pin Registered RDIMMs; UDIMM or SODIMM modules will not fit or function. Confirm your configuration matches the 1Rx8 rank and 1.1V voltage specified for this kit.

Sixteen-module kit simplifies deployment

The package delivers all sixteen 16GB modules in a single matched kit so you can fill every supported slot at once. Pre-validated rank, voltage and timing eliminate the guesswork of mixing individual sticks. No heat spreaders are included, so ensure your chassis airflow meets the server's thermal design.

Questions about this item

Does the kit contain all 16 modules or do I need to buy extra DIMMs?

The package includes 16 modules totalling 256 GB, so no additional DIMMs are required for a full population.

My board has 16 DDR5 slots — is this 16×16 GB kit the right match?

Yes, the kit provides one 16 GB RDIMM for each of the 16 slots, matching the board's maximum supported capacity.

Will the DDR5-6400 speed run at 6400 MT/s on my Supermicro H14DST-F?

The modules are specced for DDR5-6400 CL52 at 1.1 V, and the kit is verified for that motherboard, so the memory controller will recognise and run them at the rated speed.
