help 280X reboots PC under heavy load ?

[abds69]

Hello, just replaced my old ati hd6770 by a sapphire R9 280X dualx. It work OOB because device id already in AMD7000.kext and in AMDRADEONX4000.kext. 

 

Stable on desktop, luxmark, geekbench, novabench, furmark (all test). All acceleration is correct in terms of benchmarks.

 

BUT, each time i ran unigine heaven 4.0(openGL), during first or secand rendering the PC hangs and reboot instantly after 10 or 20 seconds of test. temperature only reach 45°C.

Also with many flash videos playing in safari , it hangs the same way.

 

Did you encounter this problem with your 280X ?

 

To precise things : 

 

The card is ok, because i dual boot with win7 64 and i can run unigine dx11 or openGL for hours without having a problem with this card.

My config :

asrock X79 Extreme 4-M 

bios to default parameters. PCIE2 or 3 same thing

6GB

I7 4930K

chameleon 2.3 

mac osx 10.9.5 (10.9.4 was having same bug)

Mac pro 3,1 , 5,1, 6,1 tried.

framebuffer Vervet, Aji, Hamachi tried.

 

For myshelf, it is so sudden , i would rather say it is a driver problem !!!! Looking at AMD7000Controller.kext , i found these parameters, do you know what they mean ?

You need more info here for anyone to be able to help. Check system.log at times of the crash and see what is being reported. What do you have for power supply? This card is wanting twice the power of the 6770 it replaced. I notice you have listed that you tested Vervet fb with this and that is not for this family of cards and will not work correctly. Before reporting back try that bench again with using GraphicsEnabler=No and having the card use RadeonFramebuffer fb and see if that completes.
