Will a Memory (RAM) Upgrade speed up my computer?
Here are some typical signs which indicate your computer could benefit from a memory upgrade:
- Applications running slowly and being unresponsive, especially when switching from one application to another.
- Parts of the display on your screen appearing to be missing
- On-screen messages explicitly refer to a lack of memory
- Activity Monitor utility (mac) or Task Manager (windows) shows a lack of free system memory
We also have a more comprehensive list of symptoms that a memory upgrade could help and a video tutorial to help determine if you need more RAM in your PC or Mac.
