    Is this RAM usage normal for Windows 8?


    Below is a screenshot showing my RAM usage when nothing much is running. It shows that I am using 2 GB with 1.9GB cached. What does this mean exactly and does this reduce the amount of RAM available to other programs to 2GB out of the 4? Thanks.

    you can read all about cached memory here

    CPU cache - Wikipedia, the free encyclopedia

    Think of the it as like "stored energy"

    Quite normal. Here is what mine presently looks like:

    Everything looks very good, about as close to the ideal as to not matter.

    The 2 GB in use might seem high but that is only because there is currently no better use for it. The memory manager always maintains control over memory usage, always with the goal of maximizing overall system performance. If you were to run a large application the current usage would be trimmed back as necessary. This is all very complex and usually works very well.

    It is normal and good to have a large value for Cached memory. In this case almost all of cached memory is on what is called the standby list. This memory serves a dual role. It is available to any application that needs it but until that happens it holds useful data. This is superior to free memory in every way. Caching has a long and distinguished history in computer systems and Windows 8 has a highly advanced version.

    Please understand that all of this is very complex. There is much going on that would be very time consuming to describe.

    I have 6GB and mine is always within a few percent of 50% also. This remains the same no matter how many programs I have running. I think this display is bogus, just giving us numbers that look good so we won't bother MS support. :-)

    It depends on how much you have running at any given time. The more programs you use the more memory required to keep your computer running smoothly.

    I.e. I do a fairly good bit of heavy program running at all times as I work with videos and such in my leisure so I sometimes can use up to around 11-12GB of memory easily. I have 16GB memory in my computer.

    One of the "secrets" Win 8 runs faster is that it keeps in RAM as much as it can, so it does not use much slower disk for that. Empty RAM is wasted RAM.

    Very true.

    And this isn't a new idea. In fact all modern operating systems do this and have done so for a long time. All versions of Windows released in the last 20 years (actually somewhat longer) follow this principle. It is just that Windows 8 does it more efficiently than older systems. The memory manager always tries to find some use for as much memory as possible, always with the goal of maximizing performance.

    Yeah, remember old "Unload DLLs" trick in XP and before ? Win7 did it much better but W8 manages them dynamically almost to perfection, excluding an occasional "Memory leak" that is difficult to diagnose and fix, caused by a bad program or driver. Some Intel network drivers seem to cause it a lot.

    Superfetch is way too overrated, it can actually slow down some application in order to start others, but you are not in control, you let Windows to decide, what you want, sometimes it is good, sometimes not.
