Wise Memory Optimizer

Wise Memory Optimizer is a free memory optimization software. This freeware supports both Manual as well as Auto-Optimization feature and you can use either or both to optimize system’s memory.

Auto Optimization has to be enabled from the extended interface (click Settings icon) and henceforth, this freeware will start to auto optimize your PCs memory. You can use and adjust the slider bar to set the limit of auto-optimization process as well a Run it when CPU is idle.

To Manually optimize your PC’s memory, you can just click on Optimize button on the interface. This will free up RAM (300-400 MB for my PC), which can be used for other process requirements.

You can view Used Memory and Free Memory of PC and a Donut chart for the same is also displayed.  You can also set it to Run When Windows Starts and it can be Minimized to System Tray when closed.

I have added this free memory optimizer software at the top of this list as I was pretty much impressed by its easy optimization process without any hassle. During the optimization, I didn’t encounter any sort of program crash or any kind of error.

HLP Free Memory Optimizer

HLP Free Memory Optimizer is another free memory optimization software that automatically optimizes the memory. It keeps monitoring the consumed memory, and auto optimizes it whenever the available memory is low. You can set the percentage of free RAM at which this software should automatically start optimizing the memory.

In addition to auto memory optimization, it lets you optimize memory manually as well. Just click on “Optimize” button for the same.

It comes with 3 different memory optimization levels: Best, Better, Good. These basically control how much memory should be freed up.

This software also works in similar manner to the one mentioned above; it moves older running programs to system page file, so as to free up available RAM.

Memory Washer

Memory Washer is another good Memory Optimizer software. With Auto Optimization feature, this free memory optimizer program can automatically optimize your PC’s memory.

Although, Auto-optimization is not a default feature but once enabled (Memory Optimizer> Program options), it starts to monitor for any memory leak or memory space consumed by unnecessary files and eventually frees them to be used when needed.

You can even set the time frame for automatic optimization and memory monitoring with this feature.

You can even limit the memory space to be freed with the slider bar (up to 2047 MB). It displays a real-time plot graph for the ongoing memory optimization process along with Memory Usage, System, and Page File information.

This freeware proves to be a good memory optimizer as it frees the memory without any glitch. The only issue I faced that while optimizing the memory, it used nearly all of my CPU. But still, it was for a minimal time and it optimized my PC memory well.


RAMRush is one of the simplest Memory Optimization software I have tested so far. It can be set to optimize PC’s memory with Auto Optimization feature, or you can manually free up memory in a single click.

You can also set the frequency of Auto Optimization process at a minimum time frame of 10 minutes.

What I found unique with this free memory optimizer is that it features 2 modes for memory optimization: Optimize RAM and Maximize RAM. The former option optimizes the memory in a simple way like any other good memory optimizer program does. The latter options enables you to maximize the optimization process up to three passes.

Besides all these, you can set it to load at system startup and optimize your PC’s memory.

With all these features, this freeware can easily optimize and recover your PC’s lost memory up to a great extent.

MemOptimize is another free memory optimizer software. It offers simple and easy memory optimization process for which you just have to click its Start Optimization button and the process will be initiated.

Although this free memory optimization program doesn’t have any other feature other than its main task, which is optimizing the PC memory, you can view Used Memory and Free Memory on its interface.

Also, the progress of the ongoing memory optimization task is displayed in the Progress Bar.

I am not sure how internally this software takes care of memory optimization, but its website mentions that it moves old applications to system page file (which is actually hard disk, instead of RAM), and this frees up space in RAM, which can further be used by the new applications that you open. This sounds like a pretty intelligent strategy to free up RAM on PC.

The downside of this software is that it does not come with auto-optimization feature, and you have to manually initiate this software whenever you think your PC is running out of memory, or you are planning to run heavy programs like games.

PC Brother Memory Optimization Free
