dave_the_scot Posted April 28, 2009 Share Posted April 28, 2009 Hi I am using Windows 7 RC and have just noticed that although I have 4GB of RAM installed, when you go into System (view basic information about your computer) from Control Panel, it quite rightly shows "installed RAM as 4.00GB, but only 3.00GB usable. Although there is probably a simple answer, can anyone please explain this? Regards Link to comment Share on other sites More sharing options...
