Dell Vostro 220S Compatible Memory

This 4GB kit contains two 2GB DDR2 modules built specifically for the Dell Vostro 220S slim tower. The unbuffered, non-ECC DIMMs operate at 800 MHz with CL6 timings and 1.8V voltage. It suits owners restoring or maintaining this exact legacy desktop platform.

Two-Module Kit Fills Both Slots

The package provides a matched pair of 240-pin sticks totalling 4GB, which matches the system's two-socket maximum. Installing both modules enables dual-channel operation where supported by the board. No heat spreaders are included, keeping the low profile required by the slim chassis.

Verify Slot Count Before Ordering

Confirm the motherboard has two free 240-pin DDR2 slots and that the BIOS recognises 2Rx8 density modules. The board accepts a maximum of 4GB, so this kit reaches that limit. Systems already populated with other modules may require removal of existing memory first.

Questions about this item

Will the 240-pin DDR2 modules need any active cooling or heat-spreader upgrades over time?

No, the kit ships without heat spreaders and runs at the standard 1.8 V, so no extra cooling is required during normal operation.

What limits total memory to 4 GB on the Dell Vostro 220S?

The system has only two DIMM slots and the chipset caps addressable memory at 4 GB, so the 2 x 2 GB kit already fills the maximum.

How much power and heat does the 800 MHz CL6 kit draw when the PC runs all day?

Each module operates at 1.8 V without ECC or buffering, keeping power draw and heat output low for continuous use.
