Crucial CT2G3S1067M 2GB DDR3 SODIMM Memory

Name: Crucial CT2G3S1067M 2GB DDR3 SODIMM Memory
Brand: Crucial
SKU: CT2G3S1067M

Overview

The Crucial CT2G3S1067M is a 2GB DDR3 SODIMM running at 1066 MT/s (PC3-8500), built to upgrade or replace memory in older Mac laptops and desktops. Crucial is Micron's consumer brand, and their Mac-specific modules are tested for compatibility with Apple hardware, which helps avoid the fitment and stability issues that sometimes arise with generic memory in Mac systems. The module supports both DDR3 (1.5V) and DDR3L (1.35V) operation, so it will work in systems that require either voltage standard.

With only 2GB of capacity, this module is realistically suited for topping off a system that already has some memory installed or for replacing a failed stick. Pairing it with a matching module enables dual-channel mode for a small bandwidth improvement. For anyone still running a 2008–2010 era MacBook or iMac, this is an inexpensive way to keep the machine functional for basic tasks like web browsing and document editing. It ships with Crucial's limited lifetime warranty, which provides some peace of mind given the low price point.

Pros & Cons

👍 Pros

Designed and tested specifically for Mac compatibility, reducing the risk of incompatibility issues.
DDR3/DDR3L dual-voltage support ensures it works across a wider range of older systems.
Backed by Crucial's limited lifetime warranty for long-term reliability.
204-pin SODIMM form factor matches the standard slot used in most Mac laptops and compact desktops of its era.

👎 Cons

2GB capacity is very modest by current standards and will not meaningfully improve heavily loaded systems.
Only useful for older Mac models that accept DDR3 1066 MT/s memory, limiting its relevance today.
A single module does not enable dual-channel mode on its own.
1066 MT/s speed is slow compared to DDR4 or DDR5 memory in newer machines.

Frequently Asked Questions

Which Mac models is this memory module compatible with?

The Crucial CT2G3S1067M is compatible with various Mac systems that use DDR3 1066 MT/s (PC3-8500) SODIMMs, including certain MacBook, MacBook Pro, and iMac models from approximately 2008 to 2010. Check Crucial's compatibility tool with your specific Mac model to confirm.

Is this a single module or a kit of two?

This is a single 2GB module. If your Mac has two memory slots and you want to run in dual-channel mode, you would need to purchase two modules separately.

Does this module support both DDR3 and DDR3L voltages?

Yes. It is listed as DDR3/DDR3L compatible, meaning it can operate at both 1.5V and 1.35V depending on what your system requires.

Will adding this module require any tools or technical knowledge?

Installing SODIMM memory in most compatible Macs requires only a small Phillips screwdriver and a few minutes. Crucial provides installation guides specific to each Mac model on their website.
