Hello, I have Gb of ram and recently upgraded from 4gb. When i had 4gb it used 30% of ram when idle. I switched to 8gb and it is using 50% when idle. I used several virus detection softwares to see if that was it. It wasn't. NowIi am also finding programs such as firefox or java using ridiculkous amounts of ram. For example; I was using firefox and was just using google. Next thing I see is a message from windows saying to close firefox casue it using too much ram. I look at the processes to see how much ram and it will be using about 3.5Gb ram... anyone have any idea how to fix?
What operating system do you have? If you're getting "out of memory" errors with only 3.5GB of RAM in use then it sounds like you have a 32-bit operating system which can only see the first 3.5GB or so of RAM.
If you want to use 4GB or more of RAM you have to switch to a 64-bit operating system.
