Question why is my pc microstuttering while playing any game?

[Punisher1241]

Hi i have microstutters on league of legends, counter strike global offensive, Ac unity and some other games. This microstutters happens rarely but they happen on every game i tested.
My pc:
Msi x470 Gaming plus
Ryzen 5 2600
GTX 1050TI
Ram 8gb 2400mhz single channel
SSD 120GB
1TB 7200RPM Hard disk ( i have tested the ssd and hdd not showing any weak or bad sector and have full health, tested on hard disk sentinel)
i tried disabling a lot of stuff Realtek audio, my ethernet driver, unplug my wifi adapter and my disk reader, but no succes. Could be a faulty ram?, this is my first focused gaming pc, bought in my local technology store here in chile called pc Factory, i have tell them and taken the pc to them but they told me everything looked normal after they tested for a week, the guy who did this told me if the problem persists he would need to RMA the gpu and other components. that would take a lot of time, so any of you can help me?. im a total noob on pc, used to play a lot on consoles so i dont know shit xD.
Thanks

sounds like your ram is lacking , if they are big games indeed

Single channel and slow ram for Ryzen...
ideally you should have gone for 3200 mhz 2*8gb

+1
Dual channel would be much better.

Yea i was stupid, my friend told me the components for a cheap and good pc, i thought that he knew a lot of the pc world but he didnt even know that ryzen processors were ram hungry. I should have searched a lot more before buying a pc. However, i get microstutters on games like league of legends (a game that says you need 2gb of ram on requirements) and csgo that needs 4gb of ram, i dont wanna spend money on 2 sticks of 3000mhz ram and still getting microstutters. Are you guys sure if i buy those, my microstuttering would be solved?. Sorry for my english. Thanks for taking the time for answering me

Are we "sure"? No. But it's the very 1st thing to eliminate. Plus, it's going to give you a noticeable performance boost.
