Dell Vostro 220 upgrade kit

This 4 GB kit contains two 2 GB DDR2 modules built for the Dell Vostro 220 mini tower. Each stick runs at 800 MHz with CL6 timings and 1.8 V operation. The unbuffered, non-ECC design matches the system's two memory sockets and 4 GB maximum capacity. Buyers needing ECC or registered memory cannot use this kit.

Thermal and power behaviour

Standard DDR2 voltage of 1.8 V keeps power draw modest for the platform. No heat spreaders are fitted so airflow through the Dell chassis handles cooling. The modules produce no audible noise during operation. Systems with restricted ventilation should verify adequate case airflow.

Included components

Two 240-pin DIMMs are supplied in the package. No software, drivers or additional accessories are bundled. The limited lifetime warranty from Computer Memory Solutions applies when purchased directly from the manufacturer. Product appearance may vary from the reference image.

Questions about this item

How do I install the 240-pin DDR2 modules in my Dell Vostro 220, and which step is often missed?

Power off and unplug the tower, open the case, align each module's notch with the slot key, press firmly until both side clips click shut, then verify the BIOS shows 4GB total.

What maintenance or replacement will this 2×2GB kit need over time?

No scheduled maintenance is required; keep interior dust-free for airflow. If a module fails, replace the pair with another DDR2 800MHz CL6 1.8V kit to retain dual-channel operation.

What limit appears first when the memory runs under sustained load?

The 4GB capacity ceiling is reached before bandwidth or thermal limits, causing the system to use slower virtual memory once all 4GB are occupied.
