256 GB DDR5 ECC RDIMM kit for Supermicro H14SST-G
This 256 GB kit consists of two 128 GB DDR5 5600 RDIMMs built for the Supermicro H14SST-G motherboard. Registered ECC architecture and 2Rx4 organisation let the board run every slot at rated speed while correcting single-bit errors. The modules operate at 1.1 V with CL46 latency and use the 288-pin RDIMM form factor required by the platform.
Registered ECC with 2Rx4 rank layout
Registered buffering reduces electrical load on the memory controller so all channels remain stable when fully populated. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unexpected reboots. The 2Rx4 rank configuration matches the density the board expects, ensuring the full 256 GB is recognised without down-clocking or capacity limits.
Verify DIMM population rules before ordering
Server memory support varies by model and BIOS revision. Consult the Supermicro H14SST-G manual for approved capacities, slot population order and any firmware requirements before installation. The kit contains two 128 GB modules only; no additional cables, brackets or software are included.

Questions about this item
Will the 2Rx4 registered ECC modules require any firmware updates or periodic replacement on the Supermicro H14SST-G?
The 2Rx4 registered ECC DIMMs are designed to run continuously without scheduled replacement; ECC corrects single-bit errors on the fly and the registered buffer reduces electrical load on the memory controller.
What limit appears first when the 256 GB kit runs at DDR5-5600 CL46 under sustained load?
The CAS latency of CL46 at 5600 MT/s sets the timing boundary; the memory controller will throttle before voltage or thermal limits are reached.
How much heat and power do the two 128 GB RDIMMs generate when the server runs all day at 1.1 V?
Each module operates at 1.1 V without a heat spreader; registered buffering keeps per-DIMM power low enough for standard server airflow to maintain stable temperatures.
