    Ridiculous amounts of caching on startup?

    I just watched my startup from the task manager in Vista 64 ult and saw cached memory go from only a few hundred MB to over 2.25 GB. Since I only have 3.25 GB available and use about 1.0 GB of physical memory for everything else, I am at a loss for why nearly all of RAM gets cached, leaving only 40 MB or so free.

    Is Vista caching as much as possible normal or is there something wrong?

    Its normal. When you will run a memory intensive task, for e.g. Open/Edit large images in Photoshop, Vista will free up memory so that it can be utilized by Photoshop.

    Superfetch uses nearly all of the RAM it can find for caching. Whenever the RAM is needed for anything else, it'll free it up. Then when you close programs, and the programs' RAM is no longer in use, Superfetch will fill up that RAM with cached stuff again.

    Vista operates on a memory management model that unused RAM is wasted RAM. So what you are seeing is normal. As others have said, the moment another app needs that memory, Vista will free it up for the app to use.
