Anyone that has troubleshooted problems with AMD/ATI graphics card crossfire configurations will probably know about Ultra Low Power State (ULPS). ULPS is a sleep state that lowers the frequencies and voltages of non-primary cards in an attempt to save power. The downside of ULPS is that is can cause performance loss and some crossfire instability. This also holds true for laptops with or without crossfire.

You can disable this feature manually by entering regedit and use 'search' files for all instances of ULPS (there will be several) and changing the value from "1" to a "0". After each instance of ULPS, check 'search' again for the next instance. Or, you can use this tool to do it for you.

  Installing new drivers will revert the settings to default...'1' = On. Remember to repeat these steps after uninstalling/installing new drivers.

OR you could just use MSI Afterburner. Starting with version 3 they added an option to disable ULPS:

Question though:

i thought uploading images are prohibited on this forum, cause i got an off-topic deleted last night by a moderator for that reason i presume. Or am i missing something ?

Just a heads up...when you install new drivers, the ULPS will be set back to default...which in ON. Be sure to disable ulps each time you change drivers.
