Hello. I got a new laptop for christmas its a toshiba satellite L750 and I got it for music production Its x64 and it has 6gb ram but it doesn't seem to be using all the ram. On my music program that I use (Renoise) It keeps having loud crunchy noises when there is too much reverb but on my mac which has 4gb ram it doesn't do that. This is because it is using up over 75% of the cpu when on my mac it only uses about 40% when playing the same song. On task manager it says it has 4gb cached memory and only 4gb is available. I'm not that smart with ram but is my computer storing some of my ram? If so how to I get it back because I really want to be able to play concerts without loud crackly noises every now and then.
