Memory usage wrong?

post #1 of 9
Thread Starter 
Alright here is the issue, and before I get into it.. I thank all assistance.

On boot, I will be using roughly 30-60% of my memory, my memory is 4gb.

I have included a picture.



As you can hopefully clearly see, I am using 35% of my memory, now if I were to add all of my usage up, I would be using around 440 K.

So, can someone explain this to me?

EDIT: I can just smell it...This is a noob question isn't it.

That's ~1.35GB or so? That sounds about right for 70 processes. I have less processes and yet use more at boot/idle (but that's likely due to having 8GB/more prefetched). That's a thought. Prefetch/superfetch may not be counted, nor may other small things. I doubt anyone will be able to look at that list on their PC, add it up, and have it match (nevermind you don't have the box checked to show all, in which case I still don't think it shows "all"). Mine doesn't either.

That list doesn't look 70 processes long; check show processes from all users.

Also, the system cache will be using some memory.

The rest are all 5kb or lower.

Look at Resource Manager (in Task Manager under Performance). Look at memory under the column Private (KB).

Private is the most important one to look at because that is the memory that will not be freed up for other processes.

I really love how just booting Windows, and playing a game will use all of my memory.

They always say "You don't need more then 4gb of memory!"... Apparently I need 8gb just to run Windows, and a game without using all of mine.

I will check, but this needs to be fixed.

Can't even enjoy my games.

Download process explorer. Check the process eating it then home in on the dll by checking properties.

If its that amount of ram at boot do a clean boot and have a look. But remember its virtual ram your applications don't see the ram only virtual space set out for them by the OS. SO clear your prefetch folder as well

Both of these two things will explain the discrepancy.

Unused RAM is wasted RAM. Whenever you see a percentage of your RAM as unused, think of it as unused resources. Windows will typically allocate around 35% of your RAM to cached programs, files, etc. for quick loading. You can disable superfectch if you'd rather see more free RAM, but it's only going to hurt loading times for programs and other frequently accessed items. And windows will pretty quickly and efficiently dump cached data/programs if there's an instant need to allocate more RAM to other processes.

I wouldn't infer performance in gaming to how much RAM windows is showing when you're at your desktop. I've had a system with 4GB of RAM showing 90% of physical memory being used (superfetch is enabled), but opening up and playing a game is no problem. Monitor RAM usage in gaming, I assure you that you aren't maxing out 4GB unless there's a memory leak.

they can't unless most games is 64bit
