Hi there , i've been using 2x4GB of Corsair XMS3 ram sticks , but the thing is i get like 25% ram usage by simply running Chrome !! Furthermore in the Task Manager under the Performance Tab i can see that my memory is 8174 , but the available is only 6025!( cached 3665 , free 2509 while writing this post with only google chrome running) Is this typical i mean that's how it should be?
