Hello, I built my PC recently using some of the cheapest new parts I could get my hands on, including a ryzen 3 1200 and an RX 570. For upgradeablity on a mobo with only two dimms, I bought a one by 8 GB 3000MHz RAM. However, I am noticing some stuttering in games. There is a CPU bottleneck here, well depending on the game of course, but in siege and CS I am noticing a bit of stuttering (mostly in siege, interesting only on DirectX not vulcan). When I open MSI afterburner, I notice the CPU is pinned which is causing the stuttering and that the GPU fluctuates from 100% and a very low usage. I get better frames on Ultra, which is a classic sign of a CPU bottleneck. As I can't overclock it, would buying another of stick of the same RAM improve my performance and stop the stuttering (from FPS drops). Also CS is like 70% CPU and 50% GPU if that helps.
