The system-tray readout shows current memory use as it changes. MemInfo lets you choose whether it displays physical RAM or the Windows page file, with values refreshed in real time.
What can the tray readout display?
MemInfo keeps a compact memory reading available from the Windows system tray. The display can show physical memory or page-file use, and you can choose whether the value represents memory that is free or in use.
As activity changes, the displayed value updates in real time. This gives a quick view of current memory use without opening a separate monitoring window.
How does MemInfo warn about high memory use?
Set the level at which MemInfo should warn you about high memory use. The warning threshold is configurable, so the alert can be tied to the amount of usage that matters for your system.
Display settings also let you choose the font used for the tray readout. Together, these options tailor the small status display and its warning behavior.
What does the memory defragmenter do?
MemInfo includes a memory defragmenter intended to free memory and improve RAM performance. This is a separate function from the live tray reading, which reports current RAM or page-file use.
