My Macbook came with 2GB of memory. Checking the Applications/Utilities/Activity monitor I could see that it was using all the memory as well as swap space on disk.
Apple only specified a maximum of 4GB memory, but I found references on the Internet that 8GB would also work. I am referring to the Macbook 2010 edition! Other versions may differ.
So, I grabbed 2x 4GB Kingston DDR3 1066 MHz memory modules at a nearby store and installed it.
Here the Apple memory specs for the Macbook 2010 edition:
- Double Data Rate Small Outline Dual Inline Memory Module (DDR SO-DIMM) format
- 1 GB or 2 GB
- PC3-8500 DDR3 1066 MHz Type RAM
As I said, I used 2x 4GB memory. Kingston (that's what I bought) or Samsung should be good choices.
Here is the Apple support page describing how to replace the RAM modules:
All you need is a very small Philips type screwdriver, the memory modules, and some 5 minutes of your time. Shut down (DON'T HIBERNATE !!!) your Macbook and follow the instructions given in the above link (check for the model you have).
After installation and reboot check the Applications/Utilities/System profiler to see that the memory is recognized. Then open the Activity monitor (also under Utilities) and check the System memory. Open Safari and load some 30 webpages in different tabs. Have you reached 5GB memory use yet? If not, open more. See how it responds to switching tabs in Safari, or opening other applications. As I write this, my Activity monitor shows me that I use 5.69GB of memory, 0 swap and 0 page outs.
The result is amazing! My Macbook is like reborn!
This was the best investment I ever made in a notebook.
For reference, I paid Euro 65 for the memory, it should be around $65 in the USA. I can't complain.
