So what's really up with the r9 390 throttling?

post #1 of 31
Thread Starter 
So guys, this is my first AMD card ever, after a long, long.... long line of nvidia cards.
I got the r9 390 asus strix. So I'm aware of the throttling issue with this card, but seriously what's the deal... Is this a driver issue or hardware issue? How can I stop it from happening?

In games (bf4) I will get core throttling all over the place, never seeing my max core clock I have set through Afterburner... However when I stress test, I will see max clocks fine, no issues, no heat issues either. What gives?

Gameplay is smooth, doesn't seem to be causing any lag or issues, but why? Is it just simply not utilizing the card fully becuase it's such a powerful card or what?

Here's the normal stress test:

when you monitor temp using GPUZ set the temp to show max. use the dropdown arrow . . .



also, use the slider to see what's going on with the cpu cores in afterburner.

Ok sure. Still no issue... First pic is with furmark stress testing. Second one is while playing BF4 maxed.

do the same with the vrms.

also, do not mix asus strix with furmark. they are like oil and water. stick with bf4. go to a mp64 game. shanghai if possible. play for 1/2 hour before checking temps.

if with the Thuban, i highly recommend monitoring cores using afterburner.

It's ok I don't do a long stress test with furmark, just a quick test to check clock stability real quick, then I move to gaming tests.
I'm not worried about my CPU temps, as I'm water cooled and have made sure I was stable a long time ago. I don't ever see over 51c.

I've been gaming for a few hours now, I think I'm actually stable.

the core looks cool. keep the vrms, especially vrm1 as cool. i mean if you can keep away from 90 - that would be ideal.

as far as the cpu . . . check the usage aside from temps. you might be maxing them out. when that happens . . . the gpu waits and might throttle.

Try setting the power limit bar to the max

Done. Still throttling but not as badly... Just upgraded to windows 10 as well so lets see if that helps any
