7990 Promblems

[mumpy]

Hi guys

I have just fitted a HD 7990 to a system that had a 6950 in it.
Have installed 13.10 drivers and the first couple of heaven benchmark
runs were 1589 on the usual settings.
I then restarted the PC and ran heaven again, this time 832 on the same settings.
Any idea what I done wrong? How do you tell if the 7990 is using both gpu`s?

Thanks

Make sure your not running in windowed mode as the 7990's second gpu will only run in fullscreen , also disable ULPS as this feature is quite broken and plays havok with multi gpu Amd configurations.

Use gpu-z to monitor what the card is doing .

Thanks again.
