Available Physical Memory

Total 3319 MB? You have the latest or at least version 1.6 of the bios? Reason for asking is your specs say 4 GB and Task Manager is showing well short of that. That and MSI has this to say about the 1.6 bios,

Update M-Flash module.
- Improved memory compatibility.
- Add Energy Star LOGO.
- Fixed system report incorrect memory size when install 4G memory.

I've learned to ignore the memory usage in Win 7. It does a great job with Super pre-fetching as well as releasing memory when needed.

I run CS5, AutoCad Architecture 2011, Office 2010 and a few other memory intensive programs on a regular basis. My "free" (or available) physical memory is never really high as Win 7 keeps a lot of information at the ready. If I use a different program, Win 7 happily reallocates the memory seamlessly and without any obvious performance degradation.

In Win 7, don't make it big deal. It is what it is and it's good! :)

Hi i have a very big problem, i just installed 8 GB of DDR3 memory, along with an intel i7 3770k. The thing is that my free physical memory is around 100-200 mb(even lower) and i don't know why. For example when i watch youtube videos they are very laggy, when i play battlefield 3 it's laggy too.

O i see, but the thing is that in task manager i found a program called pravy.exe(another program that might cause th problem was cmdhosts.exe, but i deleted it), every time the program is running the pc becomes laggy. I tried to delete it but it continues reapearing now i installed avast antivirus and deleted all the infected and now it runs better.

But for my curiosity, does anyone encounterd such problem with these executables ?
