Self-upgraded the iMac (mid-2011) RAM to 16GB
It is Comex (for those who don’t know, it is a computer show in Singapore)! Went down with my colleagues and picked up two sets of 4GB RAM (Kingston 4GB 1333MHz) at $33 each

First thing I did after stepping back into the house? Dug out the screw driver, went to the study room and start installing the RAM sticks. Upgrading the RAM on the iMac 27-inch is a straight forward process, even Apple put up an article on how to install or remove memory. Just be careful not to drop your iMac while shifting it around.
The memory upgrade process took me less than 10 minutes. System booted up normally and the “About this Mac” reflected the correct amount of RAM.

You might ask me why I need so much memory? I do play with a bit of virtual machines (VM) so having some spare memory is always good as sometimes I boot up multiple VM to try some stuffs.
Well, so do you need to add memory to your iMac? If you are seeing the beach ball more often and Activity Monitor shows that you have low amount of free System Memory. It is probably time to add some memory. 🙂
