  • 384 GB total capacity across eight 48 GB modules for dense server workloads
  • DDR5 6400 speed with CL52 latency delivers rated throughput for the Supermicro H14SSL-NT
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated channels
  • 1 V operation matches the board's memory-controller specification exactly
  • 288-pin RDIMM form factor fits the required server slots without adapters

Targeted Server Memory Upgrade

This 384GB kit contains eight 48GB DDR5 6400 registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H14SSL-NT motherboard expects. It is intended for administrators expanding memory capacity in compatible Supermicro servers that require fully populated registered DIMM slots.

Build Integration Requirements

The modules use the 288-pin RDIMM form factor and registered architecture, so the motherboard must support registered ECC DDR5 and the specific population order outlined in its manual. The kit frees the installer from mixing capacities or speeds because every slot receives an identical 48GB 2Rx8 module validated for this platform.

Thermals and Power Profile

Operating at 1.1V without heat spreaders, the modules rely on the server's directed airflow for cooling. Registered buffering reduces electrical load on the memory controller when all eight slots are populated, and ECC corrects single-bit errors in real time to maintain stability under continuous enterprise workloads.

Questions about this item

Will the 1.10 V operating voltage hold steady under continuous server load without heat spreaders?

The modules run at the standard 1.10 V DDR5 level; registered buffering reduces electrical load on the memory controller so all eight slots can stay populated at the rated 6400 speed.

How much heat and fan noise will eight 48 GB RDIMMs add to a fully populated chassis?

No heat spreaders are fitted; registered ECC modules typically run cooler than unbuffered equivalents at the same 1.10 V, but actual thermals depend on your server's airflow design.

What motherboard features must already be present for this 384 GB kit to function?

The board needs 288-pin DDR5 RDIMM slots that support registered ECC memory and a population rule allowing eight 2Rx8 modules at 6400 MT/s.
