MemInfo – A Real-time Memory & Page file Usage Monitor

I’m one of those people who like to know what is going on in the background on my Windows computer. I used to manage them with the Task Manager, Widgets and freeware to find out which  program is running, what is my memory usage, etc. And then I came across this nifty little utility called MemInfo!

MemInfo will display  the current memory usage of Windows in the system tray. Current memory means both the Physical memory and the Page file in real-time. It’s highly customizable as well. Under settings you can choose to show page file instead of physical memory or change the display to show free memory and the actual percentage.


You can right click on MemInfo in System tray to make it show you more details about the Memory usage like the top 5 processes, Physical memory usage, Page file usage and Memory Defragmenter.


You can also set up alerts if your usage crosses a certain percentage, it can be done from the Settings window. You have a couple of themes from which you can choose apart from being able to change the font and display options as well.


I was not sure about the Memory Defragmentation option because I didn’t find any visible changes but according to developer the way to test is:

The defrag memory module should be instant, but there is no guarantee that a significant gain in memory is obtained. The best way to test the defrag module is to open some applications, then close them, and try to defrag. A drop in memory should be visible in MemInfo own tray value (you can also open the Windows Task Manager to confirm)

Sometime if you have more GB of RAM, under Settings make sure you select “Optimize GB values” otherwise the display won’t be shown correctly.

Go to the developer’s website to download the application.

  1. In serious independent testing, memory-freeing and management apps like this tend to not really be very effective. In Windows XP, maybe; but starting with Vista and continuing on into Win7 (and I’ll bet Win8, too), these kinds of apps tend to be kinda’ pointless.

    Among the ones that sit in the system tray, the little “Memory Optimizer” in Glary Utilities is actually, surprisingly, about as good as any out there. But even it doesn’t do what most users would like.

    The truth is that the hands-down best tool for memory management is this one…

    ….called “CleanMem” by PCWinTech. The freeware version is all anyone needs.

    Its salient benefit is that, unlike nearly every other memory tool out there, CleanMem launches every few minutes (however often you specify), then quickly cleans stuff, and closes. It’s actually the Windows Scheduler that periodically runs it. If you seriously read, and bother to really and truly understand, everything on the webpage to which I link, above, you will understand what makes this little app special… and also superior to pretty much anything else out there.

    It’s not that the one recommended in the article to which this is a comment is bad. It is not. It’s fine… just about as good as most of the rest out there. The problem, though, is that starting with Vista, they’re all kinda’ pointless… even, to some degree, the little Glary Utilities one that I mentioned, herein (although of the ones out there, it’s one of the best… unassuming little tool that it is).

    For the real deal, though, I could not more strongly recommend “CleanMem” by PCWinTech. It’s definitely functional, and VERY cool. And free.

    Hope that helps!
