Supermicro H14SSF DDR5 kit

This 192GB kit contains four 48GB DDR5 RDIMMs built for the Supermicro H14SSF motherboard. Registered ECC modules with 2Rx8 organisation run at 4800 MT/s and CL40 latency on 1.1V. The exact-match specification ensures the memory controller recognises full capacity at rated speed.

Installation and population rules

Modules use the standard 288-pin RDIMM form factor and must be seated in the board's approved slot order. Registered buffering reduces electrical load so all slots can be populated, while ECC corrects single-bit errors automatically. The manual's population table and DIMM orientation notches prevent mis-installation.

DDR5 RDIMM practical limits

DDR5 RDIMM topology allows higher densities than unbuffered alternatives, yet maximum capacity per channel and supported ranks depend on the platform's memory controller. Mixed-rank or mixed-speed configurations can force the system to run below 4800 MT/s. Always verify the motherboard's qualified-vendor list before adding modules.

Questions about this item

How can I confirm the kit is running at DDR5-4800 CL40 after installation?

Check the BIOS or a tool such as CPU-Z: all four slots should show 4800 MT/s, CAS latency 40, 1.1 V and registered ECC operation.

What does the package contain and is anything else required?

The box holds four 48 GB DDR5 RDIMMs for a total of 192 GB; no extra cables, brackets or software are needed.

Why choose the 192 GB (4 × 48 GB) 2Rx8 kit instead of a different capacity?

This exact 2Rx8 registered ECC configuration matches the Supermicro H14SSF memory-controller requirements for full-speed, fully-populated operation.
