Memory Warden

Click here to jump to the latest download below.


Memory Warden monitors your system memory usage (% RAM). When usage gets too high, this program can alert you and optionally close programs to prevent computer lockup, even when your mouse cursor is not responding.

This program was written for people without the time or technical expertise to investigate why their computer is slowing down (such as busy stock traders). To accommodate all levels of urgency and autonomy, there are four different actions that may be set at any percent level:


(1) quiet background warning
A passive warning that will not interrupt whatever you are doing.

(2) alert with pop-up warning
An aggressive warning that will pop-up over any windows you have open.

(3) end memory hogs from kill list
Will automatically close programs, but only those from a list that you build.

(4) end any memory hogging program
Will automatically close any program.

To prevent a program from being automatically closed, add it to your Safe List in Advanced Settings.

Suggested Use

Create warnings (using actions 1 & 2 above) for when your memory begins getting high (70% to 85%). This will give yourself a chance to gracefully close programs. The warnings will tell you who the memory hogs are.

When system memory usage reaches 95% or higher, have Memory Warden automatically end the memory hogs in case your computer begins locking up (using actions 3 & 4 above).

Using the Kill List

Some users will want Memory Warden to automatically close specific programs before others. You can do this with the preferred kill list in Advanced Settings. For example, add Chrome, Internet Explorer, and Firefox to this list. Then use action “(3) end memory hogs from kill list”.
