Exact-match DDR5 ECC RDIMM for Supermicro H14SSL-N

This 48GB DDR5 4800 RDIMM delivers registered ECC memory built to the Supermicro H14SSL-N motherboard's specifications. It operates at 1.1V with CL40 latency in a 2Rx8 configuration. The 288-pin module installs directly into the server's DDR5 RDIMM slots.

Verify DDR5 RDIMM slot population rules before

Check your motherboard manual for supported capacities per slot and the required DIMM population order. The board only accepts registered DDR5 RDIMMs, not UDIMMs or SODIMMs. Confirm the BIOS is current enough to recognise 48GB modules at full speed.

Registered ECC architecture offloads the memory

The registered design buffers address and command signals so every populated slot runs at the rated 4800MT/s without overloading the controller. On-die ECC corrects single-bit errors in real time, preventing silent data corruption. No heat spreader is fitted, so ensure chassis airflow meets the server's thermal guidelines.

Questions about this item

Does the 48GB DDR5 4800 CL40 RDIMM kit include anything besides the memory module itself?

The package contains only the single 48GB DDR5 4800MHz PC5-38400 2Rx8 1.1V CL40 288-pin ECC Registered RDIMM. No heat spreader, cables, tools or documentation are included.

My Supermicro H14SSL-N has multiple DIMM slots — should I choose this 48GB 2Rx8 module or a different capacity?

This specific 48GB 2Rx8 Registered ECC RDIMM is verified for the H14SSL-N. Check your motherboard manual for approved population order and maximum supported capacity per slot before deciding whether to add one module or fill additional slots.

What does the 4800 speed rating actually deliver once the module is installed in the H14SSL-N?

At 4800 MT/s (PC5-38400) with CL40 latency and 1.1V, the module runs at the server's rated DDR5 speed, providing the full 48GB capacity with ECC error correction and registered buffering for stable operation across all populated slots.
