PS: There is a reply to this post stating that putting a page file on RAM disk makes no sense. Let me explain. If the system has 4GB RAM and you make a 2GB RAM disk and put the page file there, then yes, this configuration makes no sense. However, if the system has 8GB RAM and you make a 4GB RAM disk (accessing the extra memory that 32 bit Windows can not reach) and put the page file (and temp folder, and turn on "ReadyBoost" and add any other frequently used files) on there, then yes, the speed up is very considerable. And "yes" is the answer, you can get software that allows you to create RAM disks above the 4GB limit on 32bit systems.
