How much physical RAM do you have? It still is a bad idea, even on a separate physical drive to have the PF setup at even the same initial size as the actual physical RAM available, unless you don't mind wasting space. I have 2g of RAM, with the PF on a separate physical drive set @150min/900max. I can see that my swap file is only using 7mgs of actual physical memory when I am running Windows, even using a lot of normal apps. I can edit a 650mg WAV file in Sound Recorder (which will take oodles of memory), and my PF usage only goes up to 11mgs usage, and I still have 1.2gs of RAM to be used when needed! As you can see, the swap file really didn't come into play.

I would get another NR if I were you; that doesn't sound correct. I use OE, and the biggest it ever got was 25-30mgs!
