GPU Core clock drops, fps drops

[Larsie115]

When gaming (happens in all games) i see the core clock dropping down every few minutes for 10 seconds with msi afterburner.

In battlefield 4 it would go from 1030mhz to 750mhz and back up for 10 seconds, in league of legends 800mhz to 600mhz.

It gives me big fps drops and i don't know what is causing this.

 

The temperature of my CPU when playing league of legends is around 55C.

My GPU around 60C.

 

It started after a few months after installing my GPU (R9 290X).

I previously had an R9 280X but it was faulty.

I don't know if it's a GPU issue.

It would be nice if someone could help me fix this problem.

I would say change driver and see what happens.

 

Alternatively you can set profiles with specific clock speeds so it may force the card to run at those.

yeah change driver

I changed catalyst from 14.12 to 14.9 but it still occured.

Well then I am confused I dunno

Edit: Maybe your power supply isn't powerful enough that would be my second guess even though it's probably not it

Is the card a reference design?

[LazyDev]

this is most likely cooling. Classic symptoms of thermal throttling. Try forcing the fans up in speed.

No, it's an MSI Twin Frozr IV card

I don't think that it's a thermal issue, but you could verify this by simply underclocking the GPU. if it stops doing this when the tempratures are even lower, I think it's safe to say themals are not an issue.

Normally the fans are around 25%, i had set it to 50% but it still happened.
