16GB DDR4 UDIMM for Dell OptiPlex 7040

This 16GB DDR4 2133MHz CL15 module is built specifically for the Dell OptiPlex 7040 SFF and Tower. It uses a 288-pin unbuffered non-ECC design at 1.2V. The part targets owners of those exact systems who need a single 16GB stick to expand memory capacity.

JEDEC compliance and lifetime warranty

The memory meets JEDEC standard specifications and is ROHS compliant, ensuring a warranty-safe upgrade that will not void the original system coverage. OWC includes an advanced replacement programme and limited lifetime warranty with free technical support. There are no bundled accessories, software or heat spreaders in the package.

Simple DIY installation with video guide

Installation is a straightforward DIY task on the compatible OptiPlex 7040 chassis; OWC provides a basic installation video for reference. The module is unbuffered and non-ECC, so it will not work in systems that require registered or ECC memory. Buyers needing ECC or registered DIMMs should look elsewhere.

Questions about this item

Will the 288-pin DDR4 module need any firmware updates or cleaning over its lifetime?

No firmware or cleaning is required; the 16GB DDR4 2133MHz CL15 1.2V 288-pin UDIMM is a passive component with no moving parts or updatable firmware.

What limit appears first when the 16GB DDR4 2133MHz CL15 kit runs at full load for hours?

The memory controller caps throughput at the rated 2133MHz PC4-17000 speed; latency stays at CL15 and voltage remains at 1.2V under sustained use.

How much heat and power does the 1.2V unbuffered DDR4 DIMM produce during all-day operation?

At 1.2V the module draws minimal power and runs cool without a heat spreader, adding negligible heat or noise inside the Dell OptiPlex 7040 SFF or Tower.
