In this review of the CMS 6GB DDR2 6400 800MHz SODIMM memory kit, the bottom line is simple: it is a focused upgrade for owners of the Early 2008 20-in iMac who need a straightforward capacity and compatibility boost. The kit includes one 4GB and one 2GB module to reach the iMacs maximum supported 6GB, and the reviewer found the package helpful for speeding up everyday tasks and extending the useful life of that specific Core 2 Duo 2.4 20-in model. Installation is easy and the product carries a lifetime warranty when purchased from the maker, which adds confidence for buyers.

Key Features

• Guaranteed compatibility: The kit is designed specifically for the Early 2008 iMac Core 2 Duo 2.4 20-in model, reducing guesswork when upgrading.
• Balanced 6GB capacity: The combination of one 4GB and one 2GB module provides the 6GB total that this iMac supports, improving multitasking and responsiveness.
• Industry standard speed: DDR2-6400 800MHz modules match the iMacs memory bus requirements for stable operation under expected loads.
• SODIMM 200-pin form factor: The compact 200-pin SODIMM design fits the laptop-style memory slots used in the iMac without modification.
• Lifetime warranty option: When bought directly from the manufacturer, the product includes a limited lifetime warranty for long-term peace of mind.

Who It's For

This kit is aimed at owners of the Apple iMac Core 2 Duo 2.4 20-in Early 2008 (model identifiers like MB323LL/A, iMac8,1, A1224) who want to reach the maximum supported 6GB memory without buying newer hardware. It suits users who run multiple browser tabs, office apps, or light photo editing and who prefer a low-cost way to speed up an older iMac.

It is not for users with newer iMac models or those needing very high memory capacity or ECC memory for professional servers. Buyers who require the absolute fastest memory speed available for modern systems should look at newer DDR3 or DDR4 upgrades compatible with their hardware.

Pros & Cons

Pros

• Easy installation makes it accessible to most users comfortable opening the iMac for memory access.
