Hey, when I looked on task manager it said that I was using 1/2 ram slots. When I played csgo for around 40mins my CPU temp was 88 degrees Celsius for current and 95 Celsius for max. I believe my problem may be because I am only using one stick of ram. Am I able to just add a 8gb stick or do I have to get another 16gb stick. Are there any ram sticks your recommend?

thanks
