Random slowdowns?

[Kobathor]

I have an issue!

 

At first, I thought it was overheating.. Nope, still 86C max. Then, CPU.. Nooope, CPU usage doesn't go down randomly.. But it IS my GPU somehow.

 

Here's an interesting picture-

 

 

Don't worry about the end, after I exited BF4, just the front and middle. Mostly the GPU Load History. See it? It's going up and down and up and down in perfect waves, only ever reaching 100% twice.

 

The GPU core stays at 1000Mhz without slowing down, so I don't know why this happens.

 

This always happens after about 10 minutes of playing ANY game, not just BF4. It's just on BF4 where it happens so often.

 

The problem is obvious- it slows down at "random," (it appears very uniform) and the FPS drops by more than half (usually from the normal 80 FPS to 25 or so) and the problem even occurs when I change the visual settings from Ultra to Low (drops from around 120 FPS to, again, 25 or so.) And I don't know why. It started around 2 weeks ago, and hasn't stopped since. It even happens in games like CS:GO, where it goes from a more extreme 250 or so FPS to 25. It's always 25, I can clearly see it on the in-game FPS counter.

Does anybody know what's happening? I don't, and removing the OC from all my parts didn't do anything. Tried removing the GPU and replacing it, tried uninstalling and reinstalling drivers, everything I know. PLEASE HELP!

this seems

to be thermal throttling but at those temps it seems weird

That's what I thought at first.. I might try reapplying the thermal compound tomorrow, that may be the issue. But, it happens in every game, even CS:GO where the GPU Usage barely gets over 60%.

**EDIT** Apologies...wrong post

Try running AIDA64 (system stability tests)

Also try running a couple of others.

 

If it fails these tests, I would recommend RMA

I can't RMA the 7970, it was bought second-hand and the cooler is messed up.
