Server-Specific DDR5 Kit

This 64GB kit contains four 16GB DDR5 Registered ECC RDIMMs built to the exact specifications required by the Supermicro H14SSF motherboard. It targets administrators upgrading or populating that specific server platform with validated memory.

Registered Architecture and ECC

The Registered (buffered) design reduces electrical load on the memory controller, allowing all four slots to run fully populated at the rated 6400MHz speed. On-die ECC detects and corrects single-bit errors automatically, preventing silent data corruption in production workloads.

288-Pin RDIMM Form Factor

Modules use the standard 288-pin DDR5 RDIMM connector with no heat spreader, fitting the board's DIMM slots directly. Installation must follow the motherboard manual's population rules to ensure the memory controller initializes every module at full capacity.

Questions about this item

Will the 1.1 V DDR5 RDIMMs need any firmware updates or reseating over their service life?

The modules run at the standard 1.10 V DDR5 voltage and are validated for the Supermicro H14SSF memory controller, so no firmware updates or periodic reseating are required under normal operation.

What limits sustained throughput when all four 16 GB 1Rx8 modules are fully populated at 6400 MT/s?

The registered buffer and CL52 latency set the timing ceiling; with every slot filled the memory controller reaches its maximum electrical load before thermal or power limits appear.

How much heat does the kit produce when running continuously in a 288-pin RDIMM configuration?

Operating at 1.10 V without heat spreaders, the four 1Rx8 RDIMMs generate only modest heat that standard server airflow handles without additional cooling.
