Exact-Match DDR5 Kit for Supermicro H14SSF

This 576GB kit contains twelve 48GB DDR5 6400 RDIMM modules built to the exact rank, voltage and timing the Supermicro H14SSF memory controller expects. Registered ECC architecture with CL52 latency and 1.1V operation delivers full-capacity recognition at rated speed for enterprise workloads.

Installing Twelve Registered DIMMs

The 288-pin RDIMM form factor matches the board's required slot type — not UDIMM or SODIMM — so modules seat in the standard DIMM sockets. Population order and maximum supported capacity vary by BIOS revision; follow the motherboard manual's approved sequence to avoid a no-post condition when all twelve slots are filled.

Suited for Fully Populated H14SSF Servers

This kit targets administrators who need every slot occupied with validated Registered ECC memory on the Supermicro H14SSF platform. Builders using consumer boards, workstations requiring UDIMMs, or systems that cannot accept twelve 2Rx8 modules should select a different memory configuration.

Questions about this item

How can I confirm the 576GB kit is running at DDR5 6400 with CL52 after installation?

Check the BIOS memory information screen or a tool such as dmidecode; it should show 12 modules at 6400 MT/s, 1.10 V, CAS 52, and Registered ECC mode.

What comes in the box and is anything else required to populate all slots on the Supermicro H14SSF?

The box contains the 12 x 48 GB DDR5 6400 RDIMM kit (576 GB total); no extra parts are needed if the board has 12 available 288-pin RDIMM slots.

The kit is only offered as 576 GB (12 x 48 GB) — how do I decide if this capacity fits my H14SSF configuration?

Consult the H14SSF manual for maximum supported capacity per socket and the approved DIMM population order; this kit fills 12 slots with 2Rx8 registered modules at 1.10 V.
