Thanks for the tip of the 0.5GB more... I'm googling it! that might be all I need...
Just to let you know that one of the machines I tested my app in is 64 bit and happened the same. The RAM consumed by the OS and other processes is already included in the 2.2 I'm telling... my app enters to work when the RAM is already consumed in ~600 MB in the 3- 32 bit machines ... in the 64 bit machine was exactly the same only that it started a little bit higher because it has windows 7... Do you know if this is normal? should I believe I have a memory bug in my application?
Thank you again,

Unfortunately, Windows 32bit only allows roughly 2.5 gbs of memory in
total regardless of the amount of memory on the system. This is a limit of
all 32bit OSs. You could try putting the /3GB switch in your c:\boot.ini
file (google it for specifics) which should give you another .5gbs of ram.
You might need to switch to a 64bit machine. Sorry...
