NEMIX RAM 8GB DDR5 4800 Module

This NEMIX RAM module provides 8GB of DDR5 memory rated at 4800MHz with CL40 latency. It is built as a 1Rx6 unbuffered UDIMM for SuperMicro workstation and server platforms. The 288-pin design fits compatible DDR5 motherboard slots directly.

Thermals and Power at 1.1V

Operating at 1.10V, the module draws minimal power during normal workloads. No heat spreader is included, so airflow across the PCB manages thermals. The unbuffered design keeps electrical load low on the memory controller.

Build Integration for SuperMicro Systems

This single 8GB stick installs into an available 288-pin DDR5 UDIMM slot on supported SuperMicro boards. It leaves remaining slots free for further capacity expansion. Compatibility is validated for the SuperMicro MEM-DR580L-SL01-UN48 part number.

Questions about this item

How do I install this 288-pin DDR5 UDIMM in a Supermicro workstation and what step is often missed?

Align the notch on the 288-pin module with the slot key, press straight down until both retention clips click, then verify the system sees 4800 MT/s in BIOS — the step often missed is enabling the correct memory profile after install.

What maintenance or replacement will this 1.10 V non-ECC module need over time?

No scheduled maintenance is required; keep slots dust-free and ensure airflow. Replacement is only needed if a module fails, which is covered by the lifetime replacement warranty.

What limit appears first when this CL40 1Rx6 kit runs sustained workloads?

The CL40 latency at 4800 MT/s sets the throughput ceiling; sustained loads will hit that timing bound before voltage or thermal limits on this unbuffered 1.10 V design.
