Apple iMac 20-Inch Early 2008 upgrade

This 2 GB DDR2 SO-DIMM is built for the Apple iMac "Core 2 Duo" 2.4 20-Inch Early 2008. It arrives as a single unbuffered, non-ECC module ready to install in one of the system's two memory slots.

Suitable for owners of the specified iMac

The kit suits users who need a direct 2 GB replacement or addition for this exact iMac model. It will not help buyers who require ECC error correction, registered buffering, larger single-module capacities, or a different DDR generation for other hardware.

DDR2 800 PC2-6400 CL6 1.8V specification

The module runs at DDR2 800 (PC2-6400) with CL6 6-6-6 timings at 1.8 V. This speed, voltage and latency combination is the single specification that decides whether the part matches the iMac's memory controller requirements.
