[SOLVED] What's the problem?

[CartopOak]

So, i built a pc, CPU: i5 8600k MOBO: B360M-HDV GPU: GeForce GT 1030
RAM: 8 gb 2400 MHz Single-Channel. And the games are lagging, and i don't know what causes it, is it because i don't have dual-channel RAM? Or maybe because the GPU is not good enough? If somebody can help me please do.

it's the gpu yes. try reducing the graphics quality in games.

Find out why the computer is lagging: some bottleneck due to a specific component, driver issue, or mis-configuration.

Task Manager, Resource Monitor, and Performance Monitor can help you identify a possible culprit.

First run and observe while not gaming. Then slide the window to one side, leave open, and observe while gaming.

Very likely that you will discover some root cause for the lagging. E.g., some backup trying to execute, some app trying to update or phone home. Maybe some unnecessary app being launched at startup and running in the background.

Your choice of hardware:
weak video card
memory speed is too slow for i5 8600k, you should use 2666MHz.
