128GB DDR5-4800 ECC RDIMM Kit

This 128GB kit contains two 64GB DDR5 Registered DIMMs rated at 4800MHz with CL40 latency and 1.1V operation. It is built for the Supermicro H14DSG-O-CPU motherboard where the memory controller expects 2Rx4 registered modules with ECC.

Suited for servers needing registered ECC memory

This kit fits administrators upgrading a Supermicro H14DSG-O-CPU platform that requires 288-pin RDIMMs. It is not for systems that accept only unbuffered UDIMMs or SODIMMs, nor for builds that cannot use registered ECC modules.

2Rx4 Registered ECC at 1.1V

The dual-rank 2Rx4 registered design with on-die ECC at 1.1V is the specific electrical signature the H14DSG-O-CPU memory controller validates during training. If your board's qualified-vendor list calls for a different rank structure or voltage, the modules will not initialise at rated speed.

Questions about this item

Will the 288-pin RDIMM modules need any firmware updates or re-seating after extended server uptime?

No firmware updates or scheduled re-seating are required; the registered ECC design is validated for continuous operation at the rated 1.10 V and CL40 timings.

What electrical or thermal limit appears first when the kit runs at DDR5 4800 continuously?

The memory controller's 1.10 V rail and CL40 timing budget set the boundary; sustained loads stay within the JEDEC DDR5 4800 specification without throttling.

How much heat and power does the 2Rx4 registered kit generate under 24/7 load?

Each 64 GB module draws 1.10 V at standard DDR5 4800 current; with no heat spreaders, airflow across the 288-pin slots keeps temperatures in the normal server range.
