Exact-match server upgrade

This NEMIX RAM module provides a 128 GB DDR5 ECC Registered DIMM built to the precise specifications the Supermicro H14SSF motherboard expects. It arrives new and ready for installation in enterprise environments that require registered memory with error correction. The 288-pin form factor matches the board's DIMM slots exactly.

2Rx4 registered ECC at CL46

The single specification that determines fit is the 2Rx4 rank organisation combined with registered ECC operation at CL46 latency. This rank structure and buffering type must match the motherboard's memory-population rules; a UDIMM or different rank configuration will not be recognised at full capacity or rated speed.

Low-voltage DDR5 thermals

Operating at 1.1 V, the DDR5 modules draw minimal power for their density and run without a heat spreader in normal server airflow. Registered buffering reduces electrical load on the memory controller, helping maintain stable temperatures and quiet operation across fully populated channels.

Questions about this item

What does the 5600 MHz speed mean once this module is installed in a Supermicro H14SSF server?

The module runs at DDR5-5600 (PC5-44800) data rate with CL46 latency when the motherboard memory controller is configured for that speed.

How does the 288-pin RDIMM interface limit what this memory can do in practice?

The 288-pin Registered DIMM form factor is required by the H14SSF; it will not fit UDIMM or SODIMM slots and the registered buffer lets the board run every slot fully populated at rated capacity.

What physical clearance and slot requirements does this 128 GB kit need to fit?

It uses a standard-height 288-pin RDIMM PCB with no heat spreader, so it fits any H14SSF DIMM slot that accepts registered modules; verify the board's population order in the manual before installing.
