how do i know crossfire is working?

[zooankski]

I have just installed a second 5850 on my ex-58a-ud5 (both in the x16 slots), connected the bridge, and enabled xfire in CCC.
Is there a way to tell it is definately working?
Also, in CCC overdrive? the second card shows 0% load and manual fan does not work? tried a reinstall of drivers to the latest 10.9 but no go.
I intend to do a full format and re install windows 7 64 next week so some answers on what is happening before i do would be appreciated.

The easiest way mate is to right click the ATI icon in your Notification area, select the No1 card / CrossFireX settings/ Show CrossFireX Status Icon. Than any app running in CrossFire will show the icon in the upper right corner of your screen.

You can also use MSI Afterburner & monitor the GPU load.

Don't worry about overdrive in CCC not displaying fan & GPU load on the second card as thats normal, but as mentioned above MSI Afterburner will display them if you wish.

any ideas if i should be able to manually control the second cards fan speed?

But u won't be able to have the 2nd fan running at a speed without it bring on a temp profile, ie you wont be able to have them both at 45% each card (

GPUZ also lets you know if its enabled and how many GPUs are detected.

It's the same with my 5970, it is supposed to do this, it's AMD's revolutionary ATI PowerPlay™ power management technology delivering high performance features when needed and conserving power when the demand on the graphics processor is low. This industry-leading technology dramatically reduces the power consumption of ATI Radeon™ graphics family of products for the optimal balance between performance and power for break-through energy efficiency.

You're probably not an idiot like I was.....

but regarding the manual fan control in overdrive: Make sure you push apply after moving the bar. For a couple of weeks I thought the fan control wasn't working, until I clicked apply button and suddenly the fan sped up.
