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 "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.

Deathcrush just pointed me to your "fix". Cheers man, it worked magic.

Now i can actually use the crossfire, rather than having to shut down one gpu to play.

Thanks again.
