768GB DDR5 RDIMM kit for Supermicro H14DST-F

This 768GB kit contains 16 modules of 48GB each, delivering DDR5-6400 registered ECC memory for the Supermicro H14DST-F motherboard. It targets administrators who need maximum supported capacity in every slot for virtualisation, databases or high-performance computing workloads.

288-pin registered modules without heat spreaders

Each module uses a 288-pin RDIMM form factor with 2Rx8 organisation and operates at 1.1V, matching the board's registered-memory requirement. The absence of heat spreaders keeps the profile low for dense server chassis, while the registered buffer reduces electrical load on the memory controller when all slots are populated.

DDR5-6400 CL52 bandwidth ceiling

The kit runs at PC5-51200 with CL52 latency, setting the practical throughput limit for this platform. Population rules in the motherboard manual dictate which slots must be filled first and may restrict maximum frequency when all 16 slots are occupied, so consult that documentation before installation.

Questions about this item

What DDR5 speed and CAS latency does this 16-module kit run at?

The kit is rated for DDR5 6400 (PC5-51200) with a CL52 latency at 1.10 V.

What physical slot type and module height does the Supermicro H14DST-F require?

The board takes 288-pin RDIMMs; these modules have no heat spreader so they fit standard server DIMM sockets.

In which order should the 16 RDIMMs be populated on the H14DST-F?

Follow the motherboard manual's population sequence — typically fill one DIMM per channel per CPU first, then add the second rank per channel.
