Hi Guys, Im running a late 2009 imac 27inch i5 with 4GB pre installed. Was mulling over the idea of pushing this up to 12GB form crucial as it's so cheap. I was just wondering if I would notice a speed difference on the basic apps on the computer such as start up and shut down, safari, word, ical, mail etc. I am not a heavy user, but would like a general increase in speed on the core programs. Would this upgrade help or would it be a waste of money. Or if anyone can give me a link to some speed results using different amounts of memory for the imac using real applications I would be grateful..Thanks.

iMac Intel i5 Quad Core, Mac OS X (10.6.7)

    Hello B:

    The answer to your question is that benchmarking your applications (and how you run them) is probably the only way to get a definitive answer.

    More memory is usually happiness, but, based on your information, I seriously doubt if you would be able to discern a difference in performance.

    As an aside, adding third-party anything sometimes causes problems….

    Ok Thanks, Barry. I guess I need to find a link if someone has already tested this. Are you saying that a 8GB increase will not speed up any of the core apps and that it is risky for my computer..

    Hello again:

    What I was trying to say (poorly, I think) was that increasing your memory from its current 4 GB to a higher number would not appreciably (or noticeably) increase speed (based on what you posted about your usage).

    I am a "plain vanilla" kind of person, so I view any modifications made by other than the manufacturer with suspicion. I would not say, however, that you would do something risky by adding memory.

    It wouldn't be risky to add more RAM; however, you need to think about whether the expense is worth the result. Doing things such as video editing/rendering, downloading/playing videos and gaming are the heavy CPU and RAM users - basics such as surfing the net, email, and word processing are not. Open Activity Monitor (in Applications > Utilities) and check your RAM usage and how much is free - leave that window open while doing your regular stuff. See how much is being used at any time and you'll better be able to make a decision.
