  • 288-pin RDIMM form factor fits the Supermicro H14SSF motherboard's memory slots

System-Specific DDR5 Kit

This 256 GB kit contains two 128 GB DDR5-5600 Registered ECC RDIMMs built for the Supermicro H14SSF motherboard. It targets administrators who need to populate every slot with the exact rank, voltage and timing the board expects.

Registered ECC Architecture

Registered buffering offloads the memory controller so all slots run fully populated at the rated 5600 MT/s, while ECC corrects single-bit errors on the fly to prevent silent data corruption.

Sustained Enterprise Load

The 1.10 V operating voltage and CL46 latency are specified for continuous server workloads rather than short bursts, keeping signal integrity stable across long-running production tasks.

Questions about this item

What does the 5600 MHz rating mean once the kit is installed in a Supermicro H14SSF?

The modules will run at DDR5 5600 (PC5-44800) at the rated CL46 latency and 1.10 V, provided the motherboard populates the slots according to its validated sequence.

How does the 288-pin RDIMM interface limit or enable capacity on this board?

The 288-pin Registered DIMM form factor is the only type the H14SSF accepts; it allows the two 128 GB modules to be recognised at full 256 GB capacity when installed in the correct slot order.

What physical clearance does the 288-pin RDIMM need to seat in the H14SSF?

Standard 288-pin DDR5 RDIMM height fits the H14SSF DIMM slots; the kit has no heat spreader, so it clears typical CPU coolers and chassis lids without extra space.
