windows xp - Available physical memory, XP



I installed a Windows XP x86 on my PC. But when I open the system information window in the System Summary tab, in the right-hand pane and at bottom the following are written:




Total Physical memory 768.00 MB
Available Physical memory 270.41 MB !!



Why Available Physical memory is 270.41 MB please?



PS: My system is very slow and also very slower when start up. Isn't that less Available Physical memory the source of that slowness?


Answer



The Operating System will always consume some amount of memory to do it's work and reserve some for caching data.




Furthermore, any programs that you might have installed and have components that load on startup will consume memory. Eg: Antivirus.



Memory is also consumed by the inbuilt graphics capabilities of your processor/motherboard.



The total amount consumed can also vary depending on how much RAM is currently available.



Finally, for a good example, I have a desktop system at home with 512 MB RAM but only 448MB is available as 64MB goes for inbuilt graphics. After booting, I have only about 80MB available and this gets used up really quickly once I open a browser, leading to slowdowns.



To boost performance significantly, perhaps you should consider upgrading your RAM.
