I checked your post hisotry and I did exactly what you said ( expcet for the metal cover removing part as this will surely void the warranty / they look into the smalleest detail here in my country to make sure they dont cover the issue within warranty) and yess I did notice a steady performace with no dips! I guess ill just buy the other 8gb ram and see if that helps me get the 150 fps on cs go for example (been getting a steady 80 fps and max 100 ) aside from that I really like this laptop as it is my first gaming one .
