I had this computer for a few years now. It had 6gb, 2 RAM sticks in it, a 2gb and a 4gb one. It ran basic games like cs:go and rocket league with great fps, like 60 and so. Recently I bought an 8gb one, single channel. Replaced the two. now just one single channel 8gb in it, but it now runs these same games poorly. Hardly can get 40 fps with the lowest settings. Why is it doing that, shouldn't it run them even better since i have even more memory? The 8gb ram is the same brand, same voltage, same speed as the other two. All of them are Crucial, DDR3, 1600 mhz, 1.5 v.
