288GB DDR5 ECC RDIMM kit for Supermicro H14SSF

This 288GB kit contains six 48GB DDR5-6400 registered ECC modules built for the Supermicro H14SSF motherboard. It targets server administrators who need maximum memory capacity in every available slot with full error correction.

Registered 2Rx8 DDR5-6400 at 1.1V with CL52

The single specification that determines compatibility is the registered 2Rx8 DDR5-6400 configuration running at 1.1V with CL52 latency. The motherboard's memory controller expects this exact rank, voltage and timing combination to recognise the full 288GB and operate at rated speed.

288-pin RDIMM installation follows board

Installation uses standard 288-pin RDIMM slots, but the Supermicro H14SSF requires a specific DIMM population order when all slots are filled. The most common issue is inserting modules in the wrong sequence, which prevents the system from booting or recognising the full capacity. Consult the motherboard manual for the approved installation steps before starting.

Questions about this item

What does the 6400 MT/s rating mean once the modules are installed in the Supermicro H14SSF?

The kit runs at DDR5 6400 (PC5 51200) with CL52 latency at 1.1 V, so the memory controller recognises the full 288 GB and operates at the rated speed when all six slots are populated.

How does the registered ECC RDIMM interface affect real-world operation?

Registered buffering offloads the memory controller, allowing every slot to run fully populated at full capacity, while ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

What physical requirements must the Supermicro H14SSF meet to accept this kit?

The board needs six free 288-pin DDR5 RDIMM slots and must follow its documented DIMM population order for 2Rx8 registered modules.
