Exact-match DDR5 RDIMM for Supermicro H14SSF

This 48GB DDR5-4800 registered ECC module delivers the precise 2Rx8 rank structure, 1.1V operating voltage and CL40 timing the H14SSF memory controller expects. The 288-pin RDIMM form factor matches the board's slot requirement so the full capacity is recognised at rated speed.

Who this suits and who should look elsewhere

Server administrators upgrading a Supermicro H14SSF platform gain enterprise stability from registered buffering and on-the-fly ECC correction that prevents silent data corruption. Builders needing UDIMM, SODIMM or non-ECC memory for workstations or consumer boards cannot use this module.

Installation notes and common pitfalls

The RDIMM seats in the standard 288-pin DDR5 slot like any registered DIMM, but the server manual dictates exact population order and maximum supported capacity per channel. Skipping the manual often leaves slots unrecognised or forces the system to run at reduced speed.

Questions about this item

Does the Supermicro H14SSF motherboard need to support DDR5 RDIMMs at 4800 MT/s and 1.1 V before I install this 48 GB module?

Yes. The board must accept 288-pin registered DDR5 ECC DIMMs rated for PC5-38400 at 1.10 V with CL40 timing, otherwise the module will not be recognized at full capacity or speed.

Can I add this 2Rx8 registered ECC DDR5 DIMM to existing registered ECC DDR5 modules already installed in the H14SSF?

Yes, provided the installed modules are also registered ECC DDR5 RDIMMs and the motherboard's population rules allow mixing ranks; the 2Rx8 organization and 1.1 V operation must match the other DIMMs for stable operation.

How can I confirm the module is running at its rated 4800 MT/s CL40 after installation?

Check the BIOS memory information or an OS tool such as dmidecode to verify the reported speed shows 4800 MT/s (PC5-38400), CAS latency 40, voltage 1.1 V, and the full 48 GB capacity per module.
