NEMIX RAM 128GB DDR5 ECC RDIMM

This registered DDR5 module provides 128GB of error-correcting memory for servers and workstations. It operates at 4800 speed with CL40 latency and runs at 1.10V. The 4Rx4 organisation and 288-pin form factor suit dense, mission-critical deployments.

Upgrading from lower-capacity DDR5 RDIMMs

Replacing smaller registered modules with this single 128GB stick increases total memory without consuming extra slots. The jump is worthwhile when workloads exceed current capacity or when ECC protection becomes mandatory for data integrity.

Build integration for registered DDR5 platforms

The module requires a motherboard with DDR5 RDIMM slots and registered memory support. No heat spreader is fitted, so airflow across the PCB must be adequate. ECC and registration free the system from single-bit errors and reduce electrical load on the memory controller.

Questions about this item

Does the 288-pin DDR5 RDIMM fit my server's memory slots?

The module uses the standard 288-pin DDR5 RDIMM form factor and 1.10V voltage, so it fits any server motherboard that accepts registered DDR5 ECC memory.

What is the correct way to seat this 128GB registered DIMM, and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify in BIOS that the 4Rx4 rank and CL40 timing are recognised.

Will this ECC RDIMM need any firmware updates or component replacements over its service life?

The memory has no heat spreader or moving parts; it requires no firmware updates or scheduled replacements if operated within the rated 1.10V specification.
