What do I need to know when buying memory for my Mac?

First thing you need to know is your Mac model and series, processor and capacity and year of make ( for example Apple iMac 3.06GHz Intel Core 2 Duo (21.5-inch - DDR3) Late 2009 ).

Then you need to determine, what type of memory is supported by your Mac ( it could be DDR,DDR2 or DDR3 ). You can easily find out this information by following step by step guide below:

If you aren't sure what Mac model you have or what kind of memory it takes, you can get your System Profile through the Apple menu. The profile will tell you what kind of memory and how much memory is in your system.

STEP 1:   Open the Apple menu ( do this by click on Apple icon located in left hand side upper corner )
Open the Apple menu, and then select About This Mac.

STEP 2:   Select "System report..."

 

STEP 3:   Hardware overview
The System Profile screen opens, showing the Hardware Overview. The Hardware Overview provides you with all the information you will need to use the Memory selector tool, such as your Mac model, model identifier, system serial number, CPU type/speed, and total memory capacity. (picture above is for illustration purpose only and actual info on your Mac may be different, depends of your Mac model)

 

STEP 4:   Current memory information
In the Contents section on the left side of the screen, click Memory. The Memory Slot information appears, showing your current memory configuration. This information helps you determine which slots are filled with which type of memory, and how many slots are still available to install new memory. ( picture above is for illustration purpose only and actual info on your Mac may be different, depends of your Mac model ( it is 667 or 800MHz if you have DDR2 model, or 1067, 1333 or 1600MHz for DDR3 models) )

 

 

COMPATIBILITY FOR MAC SYSTEMS.

Engineered to be compatible with your Apple® system, Crucial® Memory for Mac takes

the guesswork out of a memory upgrade. Since Apple systems often have very specific

memory requirements, including particular component densities, speeds, and SPD

programming specifications, it’s important to buy your memory from people who know

Apple computers inside and out. With over a decade of experience manufacturing and

developing memory for Apple systems, we make it easy to find memory that’s been

designed specifically for your system.

 

RELIABILITY FOR MAC SYSTEMS.

If you’re an Apple computer user, you probably expect intuitive, reliable performance

from your system. We think memory should work the same way, too. For each module

we manufacture, we send it through a rigorous testing process to ensure that you’re

getting a reliable, high-performance memory solution. Every module that leaves our

doors has been extensively tested at the component level for voltage and temperature

resistances, signal integrity, and software compatibility. Even better, our modules are

lead and halogen-free.* The result? Reliable memory that meets or exceeds Apple’s own

memory requirements.
