  • 256 GB total capacity from eight 32 GB modules for dense server workloads
  • DDR5 5600 speed with CL46 latency delivers rated throughput on supported platforms
  • Registered ECC RDIMM architecture offloads the controller and corrects single-bit errors
  • 10 V operation matches the board's voltage requirement for stable full-population runs
  • Verified 288-pin fitment for the Supermicro H14SSF motherboard memory slots

Exact-fit server memory kit

This 256 GB kit delivers eight 32 GB DDR5 RDIMM modules built to the Supermicro H14SSF memory-population rules. Registered ECC architecture and 1.10 V operation let the board recognise full capacity at the rated 5600 MT/s speed without manual tuning.

Capacity and headroom

Eight dual-rank 2Rx8 modules populate every slot the platform supports, giving 256 GB of addressable memory for virtualisation hosts, database buffers or large-scale analytics. Workloads that exceed this footprint will require a platform with higher per-slot density or additional memory channels.

Thermals noise and power

Bare modules without heat spreaders rely on chassis airflow, so fan speed and inlet temperature determine thermal margin. Registered buffering reduces electrical load on the memory controller, keeping per-module power draw low at the standard 1.10 V operating point.

Questions about this item

Will this 288-pin DDR5 RDIMM kit work in a Supermicro H14SSF that already has other DDR5 modules installed?

The Supermicro H14SSF requires 288-pin DDR5 RDIMMs; mixing different DDR5 kits can prevent the system from running at 5600 MT/s or recognizing the full 256 GB capacity. For guaranteed operation, populate all eight slots with this matched 8×32 GB kit.

How can I confirm the kit is running at DDR5-5600 CL46 1.1 V with ECC active after installation?

Enter the BIOS or use a hardware-info tool and verify the memory speed shows 5600 MT/s (PC5-44800), CAS latency 46, voltage 1.10 V, and that ECC is reported as enabled for all 256 GB.

What exactly ships in the box and is anything else required to install it?

The box contains eight 32 GB DDR5 5600 CL46 1.10 V 2Rx8 288-pin ECC registered RDIMMs — a complete 256 GB kit. No additional parts are needed; the modules install directly into the H14SSF DIMM slots.
