Exact-Match 768GB DDR5 Kit

This 12-module kit delivers 768GB of DDR5 6400 ECC registered memory built to the Supermicro H14DST-FL motherboard specifications. Each 64GB module operates at 1.1V with CL52 latency and a 2Rx4 organization. The 288-pin RDIMM form factor matches the board's registered DIMM requirement precisely.

Upgrade From Lower-Capacity Kits

Replacing a smaller DDR5 kit with this fully populated 12-module set lets the server address its maximum supported memory capacity in a single step. The jump is worth it when workloads exceed the limits of a partial fill and the board's population rules allow all slots to be occupied.

Sustained Load Stability

Registered buffering reduces electrical load on the memory controller so every slot runs at the rated 6400 speed continuously. ECC corrects single-bit errors on the fly to prevent silent data corruption during long-running compute jobs. The 1.1V operation keeps power draw consistent across the full kit.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H14DST-FL motherboard slots?

Yes, the kit uses 288-pin DDR5 RDIMMs, which is the exact form factor the H14DST-FL requires; UDIMM or SODIMM modules would not fit.

What is the correct population order for the 12 modules on the H14DST-FL?

Follow the motherboard manual's approved DIMM population sequence; the kit's 2Rx4 registered modules must be installed in the specified slot order so the memory controller recognises the full 768 GB capacity.

Do these modules have a heat spreader that could need cleaning or replacement later?

No, the modules are supplied without a heat spreader, so there is no spreader to maintain or replace during the product's lifetime.
