Crossfire usage

[Mirmo]

Morning all!

Was having a little tinker with my crossfire 7850's last night so I'm nice and ready for BF4.

I ran 7850 all ultra with HBAO and I have 1 gpu at 99% usage and the second at around 50%.

Does this mean one card is being throttled or are there other causes for this? I upped voltage in case the second card needed it but it made no difference.

Cheers for any input!

Make sure you disable ulps. They is couple ways on doing this with msi afterburner beta or trixx.

Or by regedit.

I did but now you've mentioned it, I've had a driver clean and re-install since so gonna check that as soon as I'm home. Cheers for the suggestion.

You must disable it each time you re install a driver.
