How come the “Total RAM” figure doesn exactly match the amount of RAM in my PC?
The “Total” RAM shown is the figure Windows believes is available in the machine. It doesn’t include memory that was allocated for DOS drivers before Windows was loaded. Note: If the figure you see is significantly lower than you expected, you should investigate to see if there are DOS drivers you can remove, (in CONFIG.SYS and AUTOEXEC.BAT). How does RAMpage free memory? Is Swap Space being used? Is it defragmenting memory? RAMpage frees memory by grabbing it and releasing it. For example, say you have 20M free and you have RAMpage set to free 10M. When you double-click, the program requests 30M from Windows and then frees that memory. What exactly Windows is doing is a closely guarded secret out of Redmond WA. My best educated guess is that Windows does some “garbage collection”, (that is it frees memory that has been discarded by processes but not yet added back to the free memory pool), unloads any unnecessary dlls, and moves current applications out to the swap file.
