  • 128 GB total capacity across four 32 GB modules for high-density server workloads
  • DDR5-4800 speed with CL40 latency delivers rated throughput for the Supermicro H14SSF
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated channels
  • 1 V operating voltage matches the platform's memory controller specification
  • 288-pin RDIMM form factor fits the motherboard's DDR5 slots without adapters

Server-grade DDR5 ECC RDIMM kit

This 128GB kit contains four 32GB DDR5 4800 CL40 registered ECC RDIMMs built for the Supermicro H14SSF motherboard. It targets administrators and integrators who need maximum registered memory capacity in a validated configuration.

Registered design for full-slot population

The 2Rx8 registered architecture buffers address and command signals so the memory controller can drive all four 288-pin slots at rated speed without signal degradation. ECC corrects single-bit errors on the fly, protecting data integrity in continuous workloads.

Replaces unbuffered or lower-capacity DDR5 RDIMMs

The jump is worth it when your workload demands the full 128GB at 4800 MT/s with registered stability and on-die ECC. Builders using consumer UDIMMs or mixed-rank modules cannot meet the board's population rules or error-correction requirements.

Questions about this item

What is the registered ECC DDR5-4800 CL40 limit that shows up first under sustained use?

The kit runs at the rated DDR5-4800 speed with CL40 latency and 1.10 V across all four 32 GB modules, so the first sustained limit is the memory controller's maximum supported frequency and rank population.

How much heat or power does the 128 GB registered ECC kit draw when running all day?

Each module operates at 1.10 V without a heat spreader, so total power scales with the four 2Rx8 ranks under load; airflow across the 288-pin RDIMM sockets keeps temperatures in check.

What must the buyer already own for this 4 x 32 GB DDR5 kit to work?

A Supermicro H14SSF motherboard with 288-pin RDIMM slots that support registered ECC DDR5-4800 2Rx8 modules and the correct population order for four DIMMs.
