Capacity & purpose

This 4 GB DDR4 module adds memory capacity to compatible Supermicro desktop systems. The single DIMM is built with Micron components and operates at the standard DDR4 voltage of 1.2 V.

Compatibility check

Verify that your motherboard accepts non-ECC unbuffered DDR4 DIMMs running at 2133 MHz with a CAS latency of 15. Confirm the board has a free 288-pin slot and that the memory population rules allow a single 4 GB rank.

Certification & testing

Supermicro certification means the module has passed the vendor’s validation suite for specific platforms. A-Tech supplements this with its own quality-assurance testing and provides lifetime warranty coverage plus US-based technical support.

Questions about this item

What comes in the box with the Supermicro Certified MEM-DR440L-CL02-UN21 module and do I need anything else to install it?

The package contains a single 4GB DDR4 2133MHz DIMM. No extra cables or brackets are required; it plugs directly into any standard 288-pin desktop slot.

Should I choose the 4GB CL15 version or a higher-capacity kit for my Supermicro system?

This module is a single 4GB stick rated at CL15. Add one if your board has a free slot and you need a modest boost; populate multiple slots with identical modules for larger capacity.

What does the 2133MHz rating actually deliver once the DIMM is seated in my machine?

The stick runs at 2133MHz with CL15 timing at the standard 1.20V, giving your Supermicro system the exact speed and latency the platform expects for stable operation.
