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.

商品問答

How much heat and power does the 1.20V DDR4 2133MHz module produce when running continuously?

The module operates at the standard 1.20V DDR4 voltage, keeping power draw low during all-day workloads.

What must my motherboard provide for this 288-pin DIMM to function?

A desktop board with a DDR4 DIMM slot that accepts 2133MHz unbuffered non-ECC memory at 1.20V.

Will this CL15 4GB stick work alongside older DDR4 modules I already have installed?

It will run at the lowest common speed and latency; mixing capacities or timings is supported but may limit performance.
