4GB DDR3 SODIMM for 21.5-inch iMac

This 4GB DDR3 SODIMM module is built specifically for the 21.5-inch iMac equipped with a 3.06GHz Core 2 Duo processor. It provides a direct memory upgrade for that model. The component is new and sourced from a supplier with 25 years of experience in computer parts.

Replaces factory memory in compatible iMac

This module upgrades the original memory installed in the target iMac system. The jump is worth it when the existing configuration limits multitasking or application responsiveness. Adding this 4GB stick increases the total memory available to the operating system and active programs.

Handles everyday workloads within 4GB limit

The 4GB capacity comfortably handles standard desktop tasks such as web browsing, office applications and media playback. It runs out when multiple memory-intensive programs are open simultaneously or when the operating system requires more space for caching. The 1066MHz speed matches the system bus of the specified iMac model.

Questions about this item

Will this 21.5-inch iMac SODIMM fit the factory memory slot without a spacer?

The module is a standard DDR3 SODIMM built for the 21.5-inch iMac 3.06 GHz Core 2 Duo, so it seats directly in the factory slot with no spacer required.

What is the correct way to seat the 1066 MHz DDR3 module so the iMac recognises the full 4 GB?

Power off, unplug, open the bottom memory door, align the notch, press firmly until both side latches click, then close the door before booting.

How often should the 4 GB DDR3 SODIMM be reseated or replaced in this iMac?

DDR3 SODIMMs have no moving parts and require no scheduled reseating; replace only if memory diagnostics report errors.
