Crossfire 7970

[dmhenson1989]

ok just ran both cards at 925/1375 which is myreference stock speed. and no crash but a fall of 8-10 fps on the hitman benchmark

 

[dmhenson1989]

Where can i go from here?

 

[wazza300]

try and catch the bsod code

you might need more cpu v with more gpu grunt

will looklike
0x000000000000000000124

 

[dmhenson1989]

just put my reference card clock to 1125/1575 and my 2nd card still at 925/1375 and no blue screen and increase of around 3 fps

Shall i boost them both up just so it blue screens so i can see the error?

 

[dmhenson1989]

OK another update just put them both at 1125/1575 and no bluescreen and im back up to 70fps with ulps enabled just going to restart pc to confirm!

 

[dmhenson1989]

It blue screen i got the stop code on camera!
STOP: 0x00000116
and no my gpu2 is 99% usage at idle!

 

[wazza300]

does it say atidiag? from a quick google its ati/amd driver related,that could be down to unstable gpu overclock

 

[dmhenson1989]

Yes but the thing is.. with ulps disabled and at those clocks i still run at 70+ fps and no crashing or signs of instability?

Is ULPS Disabled a MUST?

 

[dmhenson1989]

It says underneath stop code atikmpag.sys

 

[dmhenson1989]

sorry with all updates just trying to give you an idea of whats going on.. now even with ULPS off the gpu2 is at full usage when im in idle?

 

[wazza300]

ulps disabled means cards run at full clocks,with it enabled it will downclock at idle

atikmpag is gpu driver related crash

 

[dmhenson1989]

Why is my gpu2 at 99% usage on idle even when ulps is enabled?

 

[dmhenson1989]

What do you suggest to do then if its GPU driver related?

 

[wazza300]

it shouldn't be,sometimes it sticks re install gpu drivers to cure it

idk maybe lower gpu oc?

you might need more cpu voltage too,

Quite curious, how did you disable ULPS in Regedit as I have in Afterburner but I believe that my Ice-Q is not liking Afterburner. My clocks lower when idle which indicates that ULPS is still enabled even though I have disabled it within Afterburner.
Also should mention that I do not use HIS iTool as I have a Twin Frozr in the first slot.

Clocks will still lower with ULPS on. With crossfire all ULPS does is turn off the second gpu when idle.

Oh right, cool to know!
Thanks Matt, was just a little skeptical as I have been told by you and others that Ice-Q Boosts don't like Afterburner but everything is going okay so far.
Just need that bit more performance from another motherboard.

Unless you've flashed the bios afterburner normally reports incorrect voltage values when using HIS Ice-Q cards. You should use His iTurbo instead and use afterburner for overlay purposes only.

 

[dmhenson1989]

So to confirm the only thing I can do is reinstall drivers to cute this? Will this cute the gpu2 99% at idle problem too?

Ahh right, when using Afterburner the Ice-Q Boosts voltage has always stuck at 1.250v but I always thought that was because it was a Boost card. Due to that I had overclock GPU1 (Twin Frozr) to 1.250v aswell. I will check out iTurbo as that could be the reason why my usage is a little too low aswell as my motherboard slacking.

Can I use the same clocks on iTurbo as I do on Afterburner?
