you need 2 cards in the same range (HD55xx in your case) and the crossfire cables to link them. plug both cards in, connect them together with the 2 crossfire bridges and tick the box in CCC

with the help of google :

New computing technology was developed circa 2007 to allow multiple discrete graphics processing units to operate simultaneously. This graphics technology allows for increased graphics efficiency without requiring a complete system upgrade. AMD, through their ATI graphics division, developed a multiple GPU configuration that utilizes onboard graphics as well an add-in graphics card simultaneously. This technology is known as hybrid Crossfire and is available with many known add-in cards.

Instructions

Download and install the latest ATI graphics driver software. This installs the "Catalyst Control Center" utility.

Launch the Catalyst Control Center utility from the desktop icon.

Click the "Crossfire" button located in the left side of the main program window.

Click the "Enable Crossfire" button located on the right side of the program window.

Click the "Apply" then "OK" buttons located in the bottom portion of the program window. This enables the Crossfire configuration that boosts the add-in graphics card's efficiency with the onboard GPU.

for those interested - and have the card that can do it :-

Disabling/Enabling AMD CrossFireX™ Power Settings
You can configure Catalyst™ Control Center to automatically set Render (secondary) GPUs in an AMD CrossFireX configuration to a low-power state when they are not in use. To enable this power saving feature, select the Disable AMD CrossFireX Power Settings option.

You can also disable this feature when you no longer need it.

Note: This feature is available only for certain graphics cards.
1.In Advanced View, navigate to the Gaming > 3D Application Settings page and scroll to the Catalyst A.I. area.
For certain notebooks, there may be two versions of this page; select the page that corresponds to the graphics processor that you want to configure. For more information, see 3D Application Settings.

If you are using an AMD FirePro™ graphics card, navigate to one of the following pages instead, and scroll to the Catalyst A.I. area of the page:

•Standard View—AMD FirePro > Graphics Performance > 3D Application Settings
•Advanced View—AMD FirePro > 3D Application Settings.
2.Select or clear Disable AMD CrossFireX Power Settings.
3.Click Apply.
