lag spikes

[NEOBLADE]

I have just installed a new gpu which is rx 6600 and i dont know why my pc keeps getting lag spikes randomly out of nowhere it has started since i installed the gpu.

btw my processor is ryzen 5 3500x, 16 gb ddr4 3200mhz ram, 550 watt psu. pls help me it just starts stuttering randomly

ok there are 2 things you can do to make this process a bit easier. 

1. have task manager open while you are gaming. when you encounter a stutter, minimise the game and screenshot the performance tab

2. after doing that, install a program called gpu-z. its quite usefull at monitoring the GPU. keep it open and do the same thing as #1 but screenshot the sensors tab in gpu-z when you get a stutter. 

 

in task manager something wrong would be a spike or large change in cpu/gpu utilization. in GPUz we are looking for the "perfCap reason" which can indicate why your gpu is slowing down (if that is the problem)

You know @TheBeanis right, you have to monitor that stuff- in most cases its easy to figure out what is wrong - we have no way of knowing,  but you have access to the computer, so you need to do this.

 

Use hwinfo64 and afterburner,  ideally not at the same time to monitor your pc.

 

Also what "500w psu"? Brand, model...

Cache from the old GPU can mess up the performance in games when installing and using a new GPU, without clearing the old driver installation first. I know this, because it happenend on my PC when I upgraded from 1080Ti to 3090. By just deleting the Nvidia cache on my PC, I removed all stutters and lags. Just a bunch of cache files in a folder somewhere in the appdata location. Has been moved around since though. Not sure where you would find this with AMD. 

I would suggest using DDU before doing anything else.
