I bought a laptop recently with Ryzen 3 2200u and vega 3 integrated graphics. It has 4 gb of ram and games stutter a lot. I am planning to upgrade to 8Gb or 12 Gb of ram. i just wanted to know if 4+8 Gb runs in dual channel like 4+4 gb. and also if 12 gb of ram will have any effect on FPS of games on my system or should i get an extra 4 gigs instead of 8 gb
