290X Crossfire Jumpy

[Diagro]

Hey

My two 290x in xfire are giving me some major issues.

in game and in benchmarks the fps is jumping all over the place, the GPU's usage is mental from 2%-100% always changing!

Any idea?

Update:
Its my Original 290x thats playing up.

I tried mining with it and its Like.. GOOO STOP GOOO Stop.... Over and over. Clocks jumping all over the place and same for the % use..

Wtf happened

 

[Diagro]

Hmm. Ok. Although in games it's hard to play due to it.

Will turn ab off and see what happens.

I know it's deffo hardware doing this as the card does suffer from coilwhine and that's changing upon each high and low.

Both cards under water so no throttling

 

[Diagro]

Yup. Matt you were right.
AB was causing the problem.

Got 4700 in valley with 1100 /1375

No idea if that's decent

Hey LT, Seems Unwinder finds what you said to be untrue, He says its not an AB bug and will not be fixed as its not an AB issue.

So… Seems i can't use AB as its cripples my cards lol

If thats not an AB issue then i don't know what is, as if i was using MSI cards i would be very upset that an MSI branded Overclocking software breaks my cards.
But I'm not using MSI cards thus I'm not too upset

 

[Diagro]

Yeah i probably didn't phrase it correctly. Its a bug in the AMD driver involving the sensor or something that makes afterburner display it like that.

I find my 290's work well with Afterburner. What settings are you using?

EDIT

Actually it seems i misinterpreted what he said.

Normal settings i suppose. But i won't use it until AMD fixes it

Any other software that will display Clocks, usage and frames on my G19 LCD?

 

[Diagro]

Ok ta chap.
Will have a look
