Enable 4gb ram usage on win 7 32-bit

Is there a limit to the RAM on Windows Vista 32-bit. For example, Can I use 8 GB of RAM on Windows Vista 32-bit.


You mean 8GB :-)
And no it will not be shown after 4GB until you switch to a 64bits OS ...


When you want to install more then 3.5 GB, in a 32 bit version it won't be used. Windows 32 will say to you that there is for example (system properties) 4 GB installed, but only 3.5 will be really used.

  1. Yes, 2, No, see this explanation
