How to use a pendrive as RAM [duplicate]

Solution 1:

If you're using Windows (Vista or Seven, I think), you must insert your pendrive in a USB version 2.0 or higher port and windows will show the AutoPlay dialog. One of the options, usually the last, is "Speed up my System". Select it and you will be taken to the properties window of the pen, in the ReadyBoost tab. From there you can make your settings.

Windows will refuse to ReadyBoost your pendrive if it doesn't meet the performance requirements!
My guess is that it also requires the NTFS file system!

Solution 2:

There's no way to use it as physical RAM, but you can page to it, on Vista/7 this can be done with ReadyBoost, on XP you can just set it to do so in My Computer > Properties > Performance > Advanced > Virtual Memory. It should be mentioned that this is no replacement for physical RAM, though.
