Server memory upgrade for Supermicro H14SSL-N

This 64GB DDR5 registered ECC RDIMM is built to the exact rank, voltage and timing the Supermicro H14SSL-N memory controller expects. The 2Rx4 organization and 1.10V operation match the board's qualified-vendor list so the module is recognised at full capacity and runs at its rated 6400 MT/s speed.

Registered architecture under sustained load

Registered buffering offloads the memory controller, allowing every populated slot to operate at full 64GB capacity without signal degradation during continuous operation. ECC circuitry detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during extended production workloads.

2Rx4 rank organisation decides fit

The module uses a 2Rx4 rank configuration that must match the motherboard's qualified memory population rules. Consult the Supermicro H14SSL-N manual for approved DIMM slot order and maximum supported capacity per channel before ordering.

Questions about this item

How much power does the 1.10V DDR5 RDIMM draw when the server runs continuously?

The module operates at 1.10V, the standard DDR5 voltage for registered ECC RDIMMs, keeping power draw low even with all slots populated.

What motherboard slot and memory population rules does the Supermicro H14SSL-N require for this 288-pin RDIMM?

The board needs 288-pin DDR5 RDIMM slots; consult the H14SSL-N manual for supported capacities per channel and the approved DIMM installation order.

Will this 64GB 2Rx4 CL52 kit work alongside older DDR5 modules already installed in the H14SSL-N?

Mixing ranks, speeds or latencies can force the controller to downclock all channels; for full 6400 MT/s stability use identical 2Rx4 CL52 modules in every populated slot.
