Hello. I have an AMD A10 5800K and i recently bought an Asus HD6670 1GB GDDR5. I searched the forums how to crossfire APU with the GPU, and it seems that i don't have any crossfire/dual graphics option in AMD Catalyst Control Center.

Model of the motherboard is Gigabyte GA-F2A55M-DS2. In bios at "gfx configuration", i set:
primary video device: NB PCIexpress
integrated graphics: force
UMA frame buffer size: auto (i tried 1GB but no difference).

Speccy does recognize both cards,the 7660D and the 6670 and it says "crossfire:D isabled"

Please give me a hand, i have no ideas what to do anymore...
Cheers!!

I don't have any northbridge configuration option available in bios...

Unfortunately, the A55 chipset on your motherboard does not support crossfire. It supports dual display but that is different - where you can output to two monitors using your onboard graphics and your dedicated graphics separately.

That's odd, because before reinstalling windows (i changed my HDD), i had the crossfire option... and it was the same W7 64bit version

There may be an option in the bios but I think that pertains to two dedicated graphics. The A55 chipset cannot do crossfire with onboard graphics AND a dedicated graphics card. Trust me, you are limited by your chipset.

Here's something from the motherboard manual:
1-6 Setup of the AMD Dual Graphics Configuration
Combining the onboard GPU with a discrete graphics card, AMD's Dual Graphics technology can provide
significantly advanced display performance for AMD platform. Read the following instructions on configuring a
Dual Graphics system.
A. System Requirements
-- AMD A series processor
--Windows 7 operating system
-- An AMD Dual Graphics technology-supported motherboard (with the BIOS updated to the latest version)
and correct driver (make sure the onboard graphics driver version is Rev. 8.981 or above)
-- An AMD Radeon HD 6000 series graphics card that supports AMD Dual Graphics technology (for more
details, please visit AMD's official website) and correct driver
B. Installing the Graphics Cards and Configuring BIOS Setup
Step 1:
Observe the steps in "1-5 Installing an Expansion Card" and install an AMD Dual Graphics technology-supported
graphics card on the PCIEX16 slot. Plug the monitor cable into the graphics card and start up your computer.
Step 2:
Enter BIOS Setup to set the following items under the Peripherals\GFX Configuration menu:
-- Set Integrated Graphics to Force.
-- Set UMA Frame Buffer Size to 512M or above.
Save the settings and exit BIOS Setup. Restart your computer.
C. Configuring the Graphics Card Driver
After installing the graphics card driver in the operating system, go to
the AMD VISION Engine Control Center. Browse to Performance\
AMD CrossFire™ and ensure the Enable CrossFire™ check box is
selected.

So, in conclusion, i'm not chipset limited...it must be something from the software.

Dual graphics is NOT the same thing as crossfire. I recommend calling your motherboard manufacturer to get a direct answer.

Dual graphics means that the computer uses the integrated graphics for low-end use (i.e. desktop, office/productivity, etc.) that depends mostly on the CPU, & uses the discrete graphics card for high-end use (i.e. 3D rendering, gameplay, etc.). As hybrid9012 states, that is not the same as CrossFire (where both GPUs are used simultaneously), but rather it switches between the two.

'Face Palm'. Flaviu D, you are still missing the point.

You APU and Graphics Card are NOT the problem, it is your MOTHERBOARD. You CANNOT crossfire with an A55 chipset! You need at least an A85/A88 chipset to crossfire. Does it say anywhere on your motherboard manual or online if 'Crossfire Supported'? No, it will not. It will only say 'Dual Graphics'.

Take a look at-
1. Gigabyte F2A85X: http://www.gigabyte.com/products/product-page.aspx?pid=...
2. Gigabyte F2AA55M: http://www.gigabyte.com/products/product-page.aspx?pid=...

#2 is YOUR MOTHERBOARD. Take a look and tell me if it say 'Crossfire Supported' on there?

Does it say anywhere on A55 or A75 motherboards if crossfire is supported? NO
Does it say 'Crossfire Supported' & 'Dual Graphics' on A85? YES

SOLUTION: Get a NEW A85 or A88 chipset motherboard OR a high end GPU.

Like spdragoo said, Dual Graphics operates the same way the Mac Book Pro utilizes dual graphics. Uses the GPU with a smaller electrical/thermal footprint for low/medium performance applications and kicks on the high end GPU when using much more intensive programs and games.
