do you not think it takes memory to run the system, I have read that win 7 can easily use 2gig of memory in just a few min, he is talking about usable memory not total system memory, or he needs to re word his post.
In Vista, at the desktop, running task mgr. with nothing running other than system and anti virus I am using 1.7gig of my 8gig of memory which effectively leaves me with 6.3gig of "usable" memory.
I'm going to apologize up front if my following post sound brash and harsh, but I can't be fluffy and nice at a time like this.
What OP is describing is Windows is only seeing 4GB out of 6GB. I can infer that OP has no parts that eat up main memory because the only one I'm aware of is integrated GPUs, and OP's system has no such thing. I'm also going to going to assume that, based on what OP has posted, that nothing would appear out of the ordinary to eat up the 2GB that's missing. When Windows detects something like an integrated GPU eating up some system memory, it will literally say something like "Physical memory available to Windows: 6.00GB available (5.50GB usable)" because Windows has dedicated 500MB just to the integrated GPU. It can't use it, and it won't let other programs use it.
Also "usable" in this context does not mean memory that's "free", i.e., you have 6.3GB of memory available to use by other programs. 1.7GB that's marked as used may or may not be Windows. And besides that, this only accounts for the private working set: data and instructions that only are useful to one program. It may account for currently used shared libraries as well.At least with Windows 7, the amount of actual "free" memory may be in hundreds of megabytes or less, because the rest of the "free" memory is used for either caching or that part hasn't been flushed yet.
