Supermicro Certified DDR4 Module
This 4GB DDR4 module carries Supermicro certification under part number MEM-DR440L-CL01-UN21 and uses Micron chips. It is built for desktop systems that require non-ECC unbuffered memory at the standard 1.2V operating voltage. The single 288-pin DIMM targets users upgrading or repairing compatible Supermicro platforms.
Sustained Load Behaviour
Rated at 2133MHz with CL15 latency, the module maintains its JEDEC standard timing without relying on overclock profiles. Because it runs at the default 1.2V, thermal output stays predictable during extended workloads such as virtualization or compilation tasks. No heat spreader is fitted, so airflow in the chassis determines long-term temperature stability.
Installation Notes
The 288-pin DIMM keys into any standard DDR4 desktop slot; alignment notches prevent backward insertion. Common issues arise when mixing this stick with modules of different rank, speed or voltage, which can prevent the system from posting. Verify the motherboard qualified-vendor list for the exact MEM-DR440L-CL01-UN21 part number before installing.
