Hi, my laptop recently has had a ram issue. One of my memory slots is broken now. I can only have one stick of ram now. So I only have one stick in of 4gb. My laptop used to have 8 gigs. Should I buy an 8gb stick to play Osu or are just 4 gigs fine? I could play Osu fine when I had the 8 gigs. My laptop would crash a lot because of the ram issue, but Osu had no lagging or glitches. I haven't played Osu since I took out the other 4gb stick. Hope someone has advice thank you.
