Computer Memory Solutions 4GB DDR2 667MHz SODIMM for Apple iMac 20-Inch 2.4GHz

System-Specific DDR2 SODIMM

This 4 GB DDR2 667 MHz SODIMM is built for the Apple iMac 20-Inch 2.4 GHz Intel Core 2 Duo. It matches the exact pin count, voltage and timing that the original logic board expects. The module arrives as a single 4 GB stick using unbuffered, non-ECC chips.

Straightforward slot installation

The 200-pin edge connector drops into the iMac’s two SO-DIMM slots without tools or firmware updates. Because the system caps total memory at 6 GB, pairing this 4 GB module with the existing 2 GB stick fills the limit; a second 4 GB stick would exceed it. No heat spreader means the board sits flush in the tight chassis.

Steady output during long sessions

Running at 1.8 V with CL5 5-5-5 timings, the stick maintains its rated 667 MHz speed through extended workloads such as video encoding or large photo batches. Unbuffered major-brand chips keep signal integrity stable, so the iMac avoids throttling or memory errors even when both slots are populated for hours.
