Server memory upgrade

This NEMIX RAM module provides 16 GB of DDR5 ECC registered memory for SuperMicro servers and workstations. It operates at 4800 MT/s with a CL40 latency and runs at 1.1 V. The single-rank 1Rx8 design uses major OEM chips from Samsung, Micron or Hynix.

Sustained workload behaviour

ECC circuitry detects and corrects single-bit errors during continuous operation, protecting data integrity in long-running server tasks. Registered buffering reduces electrical load on the memory controller, helping stability when multiple modules populate a channel. The 1.1 V supply limits heat output under extended load.

Pre-installation checks

Verify that your SuperMicro system accepts 288-pin DDR5 RDIMM modules and supports the PC5-38400 speed grade. Confirm the motherboard or server manual lists compatibility with registered ECC memory of this rank and voltage. Ensure an available DIMM slot exists for the single 16 GB module.

Questions about this item

How much power does the 1.10V 4800MHz registered DIMM draw when the server runs continuously?

The module operates at 1.10V, the standard voltage for DDR5 4800, so power draw stays within the JEDEC limit for that speed grade; actual watts depend on workload and the platform's memory controller.

What motherboard slot and chipset support are required for this 288-pin ECC RDIMM to function?

You need a Supermicro server or workstation board with DDR5 RDIMM slots and a chipset that supports registered ECC memory; the 288-pin keying prevents insertion into non-DDR5 or unbuffered slots.

Can this CL40 1Rx8 registered DIMM share channels with other DDR5 ECC RDIMMs of different capacities or ranks?

Yes, DDR5 registered ECC modules of varying capacities and ranks can populate the same channel provided the platform's memory controller supports mixed configurations; populate slots per the vendor's population rules.
