Theoretically... NO. The principle of Virtual Memory is to "enlarge" RAM size with a portion (file) of the hard disk. For example you have 128 MB RAM and use a page file (Virtual Memory) of 256 MB, the applications (and Windows itself) will see a total of available memory of 128+256=384 MB RAM!! (even if you have phisycally only 128).

A RAM drive is a hard disk emulation in RAM, therefore for 256 MB RAM and a 128 MB RAM drive you get a total memory of 256-128=128 MB RAM available! You practically decrease the amount of the phisycal RAM by using a RAM drive. yYou cannot use somthing you don't have (extra emulated RAM...).

Therefore what you want to do is a contradiction of terms. What you should do (or at least I think you want to do)is to DISSABLE VIRTUAL MEMORY if you do have 256+ MB RAM. In this way, Windows will not use the Virtual Memory at all (no hard disk space for RAM emulation), limiting itself to the phisycal RAM installed.

I do hope that this clarify the things for you...

Lusu.
