NEMIX RAM 16GB DDR5 4800 ECC RDIMM

This NEMIX RAM module provides 16GB of DDR5 ECC registered memory rated at 4800MHz with CL40 latency. It is built for Supermicro server and workstation platforms such as the SYS-211E-FRN2T and X13SEM-F. The 1Rx8 organisation and 1.1V operation suit high-density registered DIMM slots in mission-critical environments.

Check Supermicro DDR5 RDIMM compatibility

Verify that your Supermicro system accepts DDR5 288-pin RDIMMs and supports the 4800MHz PC5-38400 speed grade. Consult the motherboard manual for approved population order and maximum registered DIMM count per channel. Ensure the BIOS is current enough to initialise DDR5 ECC registered modules correctly before installation.

Passive design runs at 1.1V with no heat spreader

The module operates at 1.10V without an integrated heat spreader, relying on chassis airflow for cooling. Registered buffering adds negligible latency while maintaining signal integrity under sustained loads. Power draw remains low for a 16GB DDR5 RDIMM, keeping thermals and acoustic impact minimal in densely populated server configurations.

Questions about this item

Does the 16GB DDR5 4800 CL40 ECC RDIMM arrive as a single stick or do I need to order extra modules?

The package contains one 16GB 288-pin DDR5 RDIMM rated at 4800 MT/s with CL40 latency and 1.1 V operation; no additional modules are included.

Should I choose the 1Rx8 16GB version or look for a different rank configuration?

This module is a single-rank 1Rx8 design, which typically allows higher memory density per channel on Supermicro platforms that support DDR5 4800 registered ECC memory.

What does the 4800 MT/s rating mean once the RDIMM is installed in a Supermicro server?

The module will run at up to 4800 MT/s (PC5-38400) with CL40 timings at 1.1 V, providing registered ECC error correction for stable server workloads.
