System-Specific DDR5 Kit

This 256 GB kit contains two 128 GB DDR5 Registered ECC RDIMMs built for the Supermicro H14DSG-OM motherboard. It targets administrators who need exact-match memory that the board recognises at full capacity and rated speed.

Registered ECC 2Rx4 Configuration

Each module uses a 2Rx4 organisation with on-die ECC and a registered buffer that offloads the memory controller. The combination lets every slot run fully populated without signal degradation.

Low-Voltage 1.1 V Operation

Running at 1.1 V reduces power draw and heat output compared with higher-voltage DDR5 server DIMMs. The modules ship without heat spreaders, relying on the chassis airflow that Supermicro platforms already provide.

Questions about this item

Will the DDR5 6400 speed run at full rate on my Supermicro H14DSG-OM?

The kit is spec-matched to the H14DSG-OM memory controller, so the 6400 MT/s rating is recognised and sustained when all slots are populated per the board's population rules.

Does the registered ECC design change how the memory controller behaves?

Registered buffering offloads the controller, allowing every slot to run fully populated at 256 GB total while ECC corrects single-bit errors on the fly to prevent silent data corruption.

What physical slot and keying does this 288-pin RDIMM need?

It requires a standard 288-pin DDR5 RDIMM slot; the module has no heat spreader, so it fits the H14DSG-OM DIMM sockets without clearance issues.
