I own a E1-570G. I bought a new set of ram : HyperX Impact So-dimm DDR3L 1600MHz 8GB (4gb x2)
The problem is that i noticed that the performance of my pc got a lot worse.
My fps dropped to 30 fps from a 120 fps ( in league of legends)
I'm sure that my nvidia geforce 720m is active when i play...but i can't explain the drop of fps
