Windows 7 On My Laptop Uses More Than Desktop

post #1 of 4
Thread Starter 
I learned today that my family's desktop computer, with 6 GB of RAM and a quad-core 2.5 GHz CPU, uses 900-1.1 GB of ram while idle. My personal Acer Aspire 5553g, now with 8 GB of RAM and a dual-core 2.4 GHz , uses about 1.3 -1.7 GB while idle. I understand that the more RAM you have, the more Windows will use, and since my Acer has 2 GB more, this may be contributing to the problem. BUT, when I had only 4 GB of RAM (last month), my Acer used about 1-1.2 GB of RAM.

I run maintenance on my computer daily and keep it in much better shape than my family's desktop. I also wiped-wiped my HD recently (DBAN) so I know my HD isn't causing any problems, as the use of DBAN did nothing to increase performance and decrease usage of anything. Neither computers have an SSD, so I think that can be ruled out.

Is my Acer's monster RAM use attributed to its lesser CPU, as compared to the desktop? Could I be "leaking" memory? Is this just a fact of life for a laptop owner?

Side question: My paging file's min. is 16MB, recommended is 11901MB, with 7934 MB, and Superfetch is enabled. Could these be of any consequence?

This week, I've been working with Ubuntu linux 12.04 and that was running idle with 200 - 700 MB of RAM, with roughly as many background programs going. So there is also that.

Very normal. I have about 2GB usage at idle with my PC 8GB ot RAM.

Your desktop uses 1.1 GB RAM and the laptop is roughly 1.3. So you're worried about this small 200 MB difference because??? MMurph, you have 8 GB of total memory - that 200 MB difference is a drop in the bucket! Why are you so worried about this 200 MB difference? Just because both machines are running the same exact OS doesn't mean it's going to consume EXACTLY the same. Factors such as what services/ drivers/ and/ software program processes running in the background will affect that.

If you're really obsessed about it - look in msconfig and see what items you can get rid of on the startup tab. Keep in mind that unchecking the items will not uninstall anything - all you're doing is preventing those programs from loading at system bootup.

    Depending on where you are getting your numbers from, much of that memory is probably being used by Superfetch.  To find out, open Task Manager and go to the Performance tab.  In the Physical Memory box, look at the "Cached" value.  Please note that the "Cached" memory is really as good as free, since Windows will immediately make it available to other applications if it is needed.  Superfetch can be using more memory on your laptop simply because you are using more (or larger) programs.
    Superfetch basically monitors what files are accessed at which times of the day, and loads them into RAM in the background shortly before that time, so that they don't have to be read from the disk on demand.  It is really like having a RAM disk caching many of your frequently used programs all the time, and since RAM can supply files much faster than a HDD, this improves performance.

    If you want to disable Superfetch (not recommended unless you have < 4 GB of RAM), open Services (press [Win]+[R], type "services.msc", and press [Enter]), scroll down to "Superfectch", double-click it, and set its Startup Type to Disabled.  Then click [OK] and reboot your computer.  With it disabled, expect programs to take longer to load.  To re-enable it, set its Startup Type back to Automatic, click [Start], and click [OK]. thumb.gif
