Dell desktop upgrade

This 4 GB DDR4 DIMM is built for the Dell Inspiron 3268, OptiPlex 5050 SFF or Tower and OptiPlex 7040 Mini Tower. It adds a single 288-pin module to systems that accept non-ECC unbuffered memory. Buyers who need ECC error correction or registered modules cannot use this kit.

Thermals and power

The module runs at the standard DDR4 voltage of 1.2 V and has no heat spreader. Passive cooling relies on case airflow, so temperatures stay low in typical office workloads. Silent operation is assured because there are no moving parts on the stick itself.

What the bundle changes

The package contains only one memory stick, so a second slot must be populated separately to enable dual-channel bandwidth. A limited lifetime warranty from Computer Memory Solutions covers manufacturing defects for the original purchaser.

Questions about this item

How do I install the 288-pin DDR4 DIMM in my OptiPlex 7040 Mini Tower, and which step do people often miss?

Power off and unplug the system, open the case, align the notch on the module with the slot key, press firmly until both retention clips click, then verify the module is seated evenly; the step most often missed is confirming both clips have fully engaged.

What maintenance or replacement will this 4GB DDR4 2400MHz CL17 module need over time?

No scheduled maintenance is required; keep interior dust-free for airflow, and replace only if memory errors appear or if you upgrade to the supported 64GB maximum across four slots.

What limit appears first when this 1.2V unbuffered non-ECC memory runs sustained workloads on a Dell Inspiron 3268?

The 4GB capacity is the first constraint; heavy multitasking will exhaust available memory before thermal or voltage limits become an issue.
