6GB of RAM on iMac7,1

Hexley said:

I currently have 4GB of RAM on my MA876LL iMac7,1. Is it worth upgrading to 6GB? I also have a MB133LL MacBookPro4,1 also with 4GB of RAM and can be upgrade to 6GB. Is it worth upgrading as well?

Are there any drawbacks in moving the RAM up to 6GB other than spending $150 worth of upgrades on 5yo Macs?

To determine if you can benefit from more RAM, launch Activity Monitor and click the System Memory tab at the bottom to check your page outs. Page outs are cumulative since your last restart, so the best way to check is to restart your computer and track page outs under your normal workload (the apps, browser pages and documents you normally would have open). If your page outs are significant (say 1GB or more) under normal use, you may benefit from more RAM. If your page outs are zero or very low during normal use, you probably won't see any performance improvement from adding RAM.
