Hello I want to purchase some memory rams i think thats how they are called and idk what i should get. Rn i have Patriot Signature Line 8GB DDR3 1600MHz CL11 Dual Rank 1.5v should i get another of those so i have 16 like will it improve fps in games or not. OR should i get HyperX Fury Black 8GB DDR4 2133MHz CL14 1.2v but then ill only have 8 cause i dont think it mathes with my actual memory right? thanks
