performance - When do you know you need more ram?


My current system is:
intel core i5-750 quad core
4gig ram 1600
600gb 7200rpm HDD
running on windows 7


When I look at the performance monitor my memory rarely goes above 50% of total memory usage.


What is the preferred memory usage percentage at any given point in time for a system to run smoothly and stable?


Answer



It doesn't really work like that on Vista or Windows 7, not anymore. Both aggressively cache stuff into RAM, and release it if more is needed for an application. I'd say you only need more RAM when you can imagine filling it up with day-to-day applications - similarly to hard drive space, you only have enough when you have more than you can fill up :)
