  • 256 GB total capacity from four 64 GB modules for maximum server density
  • DDR5 5600 speed with CL46 latency delivers rated throughput for Supermicro H14DSG-O-CPU
  • Registered ECC RDIMM architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation at 2Rx4 rank matches the board's memory controller requirements
  • 288-pin DDR5 form factor ensures exact fitment in the target motherboard

Exact-match DDR5 kit

This 256GB kit contains four 64GB DDR5 5600 RDIMMs built to the Supermicro H14DSG-O-CPU memory controller specification. Registered ECC modules with 2Rx4 organisation run at 1.1V CL46 so the server recognises full capacity at rated speed without manual tuning.

Registered ECC stability

Registered buffering offloads the memory controller allowing every slot to stay fully populated at full capacity. On-die ECC corrects single-bit errors in flight preventing silent data corruption and unplanned reboots in production workloads.

256GB headroom

Four 64GB modules fill the board's supported population and deliver 256GB of addressable memory for large databases and virtualisation clusters. Capacity stops at this kit maximum; workloads needing more memory require a platform with higher per-slot limits.

Questions about this item

Will the 288-pin DDR5 RDIMMs need any firmware updates or reseating after the server has been running for months?

Registered ECC DDR5 modules are designed for continuous operation; no periodic firmware updates or reseating are required once the kit is installed and recognised by the Supermicro H14DSG-O-CPU board.

What limits sustained throughput first when all four 64 GB modules run at DDR5 5600 CL46?

The memory controller on the Supermicro H14DSG-O-CPU board governs maximum sustained bandwidth; with four 2Rx4 ranks populated the controller reaches its electrical and timing ceiling before the DRAM chips do.

How much heat and power does the 256 GB kit draw at 1.1 V during all-day workloads?

Each module operates at 1.1 V without a heat spreader; total power draw stays within standard DDR5 RDIMM limits and passive airflow in a server chassis keeps temperatures in the normal operating range.
