    As the title says, is 8GB ram worth it just for Windows SuerpFetch?

    I rarely go over 2.5GB with 4GB ram but since I've ruled out SSD's as an upgrade and sticking with a Momentus XT which has 4GB NAND Flash for caching would an extra 4GB (8GB total) for SuperFetch caching sorta give me the same effect (make up) for a real SSD?

    I know by going 8GB as oppose to 4GB Windows will use 2GB on idle at the very least as oppose to 1GB idle with 4GB ram add another 2GB for programs that I regular use and the remaining 4GB for SuperFetch caching pretty much equaling the same size of the Momentus XT's NAND Flash cache.

    Worth it, bare in mind I will not go over 4GB even with 8GB ram it's just for SuperFetch caching to give me more pre-cache like the Momentus XT's 4GB NAND Flash since I'm not spending on a SSD anymore.

    That's not how it works s:

    Your HDD would still be the bottleneck for anything you'd be doing I/O wise, you can't just tell windows to dump any specific set of 4GB of data into RAM.

    You're better off getting a 40GB SSD, installing windows to it, and then using your HDD as a media/storage drive.

    Windows will prefetch for buffering IO but after 4GB the benefits are not especially noticeable.

    I ruled out SSD's please don't try to advise me otherwise..

    I've made up my mind and going to be ordering 8GB anways with the current prices for DDR3 I'd have to be crazy not to, besides I can use more ram dedicated for Intel HD 3000 and pretty much set for W8.

    I made up my mind shortly after I posted but wanted to hear what others have to say, I wasn't trying to be a smart a@*.

    Thanks for the inputs,

    Edit:

    Too bad I do not my HM65 chipset does not support Intel's Smart Response Technolgy or else I'd be more than willing to invest $100 on a Intel 311 20GB for caching.

    Superfetch in Windows 7 won't use the 8 gb, only Vista did. You could look into some third-party caching software like Fancy Cache.

    FancyCache Overview

    Other than that, get more RAM when you need more RAM.

    T1mur, what is that based on? As far as I know Windows 7 absolutely will use that 8GB... for prefetching.

    Windows superfetch is based on usage. It can use almost all available ram or it barely use much. The Intel HD 3000 can only use so much system RAM. You may want to find out exactly how much. The address space available to the Intel HD is dependent on it's design, BIOS and motherboard address mapping.

    Superfetch only prefetches data that it deems worth. On my system it only fills about 1 gb of RAM by itself, even though I often load data where even a single file can be more than 1 gb in size.

    Standby + Modified = Cached data

    What you need to understand is that Superfetch is *not* equal to Cached data. Anything you *manually* load yourself will be put into the cache, which is a way to fully utilize the 8 gb. But Superfetch won't do it for you anymore, because people found it to be too aggressive with Vista and were unnerved by constant HD "trashing noise".
