  • 288 GB total capacity from six 48 GB modules for maximum memory density
  • DDR5-4800 speed with CL40 latency delivers rated throughput for server workloads
  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically
  • 1 V operation matches the board's voltage requirement for stable full-population runs
  • Verified compatibility with the Supermicro H14SSL-N motherboard ensures correct fit and recognition

Exact-Match DDR5 RDIMM Kit

This 288GB kit contains six 48GB DDR5 4800 Registered ECC RDIMMs built for the Supermicro H14SSL-N motherboard. Each module runs at 1.1V with CL40 latency and a 2Rx8 organisation so the memory controller recognises the full capacity immediately. It targets server administrators who need maximum registered memory in every slot without manual tuning.

DDR5 4800 Registered Limits

The DDR5 4800 standard caps transfer rate at 4800 MT/s and the registered buffer adds one cycle of latency versus unbuffered modules. Population rules on the H14SSL-N dictate which slots must be filled first, so full-speed operation depends on following the board's validated sequence. Buyers who need higher bandwidth or lower latency than the JEDEC 4800 baseline cannot meet that need with this kit.

Build and Daily Implications

Modules ship without heat spreaders, relying on chassis airflow to manage thermals in dense configurations. The 288-pin RDIMM keying prevents accidental insertion into UDIMM or SODIMM slots, and the registered architecture keeps electrical loading stable when all channels are fully populated. Technicians who prefer heatsinks or who run open-air test benches should verify cooling adequacy before deployment.

Questions about this item

Should I choose the 6x48GB kit or a different capacity for the Supermicro H14SSL-N?

The 6x48GB kit provides 288GB total capacity across six slots, matching the board's RDIMM population rules for full-speed operation at DDR5-4800 with CL40 timing and 1.1V.

What does the 4800MHz rating mean once installed in the H14SSL-N?

The modules run at DDR5-4800 (PC5-38400) with CL40 latency at 1.1V, and the registered design lets the memory controller drive all six slots at that rated speed without downclocking.

How does the DDR5 RDIMM interface affect performance on this motherboard?

The 288-pin registered DDR5 interface buffers address and command signals, allowing the H14SSL-N to run all six 2Rx8 modules at the full 4800MT/s data rate while ECC corrects single-bit errors in real time.
