Exact-Match Server Upgrade

This NEMIX RAM kit delivers 256 GB as two 128 GB DDR5 Registered ECC RDIMMs rated for 5600 MT/s at CL46 and 1.1 V. The 2Rx4 dual-rank organisation and 288-pin form factor match the Supermicro H14SSL-NT motherboard's memory controller expectations so the full capacity is recognised at rated speed without manual tuning.

Registered ECC Stability

Registered buffering reduces electrical load on the memory controller, allowing every populated slot to run at the full 256 GB capacity. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots that would otherwise reach production workloads.

Verify Population Rules First

Server memory support varies by model and BIOS revision, so consult the Supermicro H14SSL-NT manual for approved DIMM population order, maximum capacity per channel and any required firmware updates before ordering. This kit is not suitable for systems that require unbuffered UDIMMs, SODIMMs or a different DDR generation.

Questions about this item

Will the 2Rx4 registered ECC modules need any firmware updates or periodic reseating after installation?

No firmware updates or reseating are required; the 2Rx4 registered ECC design is recognised by the Supermicro H14SSL-NT memory controller at full 256 GB capacity and rated DDR5 5600 speed.

What limits sustained throughput first — the CL46 latency or the 1.1 V power envelope?

The CL46 CAS latency at DDR5 5600 sets the timing ceiling, while the 1.1 V operating voltage keeps power draw within the server platform's memory-subsystem budget.

How much heat do the bare 288-pin RDIMMs generate when the server runs all day at full load?

Without heat spreaders the modules rely on chassis airflow; at 1.1 V and DDR5 5600 the registered ECC design keeps thermals within normal server operating limits.
