My iMac only has 3 GB of RAM and the most it can support is 4 GB (I think? It's an original Al iMac from 2007. It came with 2 GB of RAM in the form of 2x1GB... I replaced one of the sticks with a 2GB 2 years ago or so.)
I'm in too tight a spot to afford a new computer and even another 2 GB stick... actually... only $14 now? That's a good deal cheaper than I expected... (I think I paid $40 a few years ago?) I may just buy one of those sticks...
Anyways, I've found the following for improving RAM usage (most of it having to do with Safari.)
1 - Never ever use the grid view. It's loading every single page that's in that view. I had had it set up to display 3x4 every time I opened a new tab or window. I changed my preferences to open everything with an empty page. This has saved me a lot of memory according to Activity Monitor.
2 - Install the ClickToPlugin extension. It blocks all Flash, Silverlight, Java, etc., from loading automatically. Saves a lot of memory.
3 - Use "purge" in Terminal. Turns all of your inactive memory into free memory... my understanding is "inactive" memory is memory that is being held onto from documents you had open but have now closed, for example. The idea is you might want to open it again right after closing it. Supposedly it's as good as free memory because the OS will go ahead and use it for other things. It seems to me that it's a nice idea, but doesn't work in practice. I have no idea why, but free memory seems a lot better than inactive.
4 - Never ever launch iMessages. I have no idea why, but that app eats memory like nothing else I've ever seen. I've had it use 2.5 GB of real memory (of the 3 GB I have!) and use up 11 GB of virtual (and it was still climbing!) It's insane! It doesn't always behave that way, but it does often enough that I've stopped trying to use it. I suspect the issue is something to do with when it hangs while downloading a picture.
Now...
does anyone have any other tips for making the most of your computers RAM?
Also, can anyone tell me exactly what I should look for when buying RAM? Am I looking at the wrong thing when I see a 2 GB stick for just $14?
