ASRock FM2A85X Extreme4-M Issue - No Crossfire Dual Graphics with 6670

Hey everyone!

So I bought this New FM2 5800k Processor. It overclocks Awesome! I have hit 4.9GHz on air and it has stayed under 46C while running Prime 95, not too shabby.

When trying to play games, BF3, on Low Settings at 1440x900 and even lower settings I would get all kinds of stuttering and really crap game play. So I thought, "I'll Add a 6670 and get more performance".

Here is what I have below

FM2 5800k Proc OC'd 4.6GHz w/Enermax Cooler
16gig DDR3-1866 G-Skill Sniper memory
Sapphire HD6670 Ultimate 1GB Video Card
450watt Antec PSU
ASRock FM2A85X Extreme4-M FM2 Mother Board
Windows 7 Pro 64bit SP1
All MS Updates and current chipset and Video Drivers listed below

"Dual Graphics Mode" will not run nor will show in the Engine Control Center. I have been reading for the last 3 days in this and cannot get my head around it. I have the primary graphics in the bios set to "Onboard" and I have matched the memory buffer with my Dedicated Card.

The PC recognizes both GPU's but will only use one. GPUz recognizes both cards but in turn just lets me know that "Crossfire" is "Disabled".

ASRock does not answer their phone calls for Tech Support. Instead they have you leave a message and then they do not call people back.

I have been happy for the past year with ASRock products as I use them in about 95% of my customers computers.

Just to add. This board does run great for web surfing watching videos etc. As a day to day PC its great! My whole purpose for building this was to build a budget PC to promote to customers for Christmas and now I am ready to throw it at the wall, lol.

More information is below if anyone has any ideas please throw me a line. It would be greatly appreciated.

FYI, I have not found anyone else online with this issue.................maybe because they are smart and only Buy Intel, lol.

My WEI Score not that it matters but it is low compared to other reported scores

Gaming Graphics: 3D Business and Gaming Graphics = 6.2


Just read the pdf on the CD. I am confused though. They list graphics cards that I cannot find. Don't tell me it's the 6000 series because those don't work when tested. Read the info taken from the included electronic PDF located on the included ASRock CD

When going through the BIOS under "Advance"--->"North Bridge Configuration" you have 4 Options Available. 1. Primary Graphics Adapter 2. Share Memory 3. Onboard HDMI Audio 4. Dual Graphics *(read below) 5. DVI Function. When I installed a Sapphire GDDR5 6670 GPU I only saw 1,2,3,5. I never saw Dual Graphics.

Option #4 if you have a 7000 Series Dedicated GPU

*This item appears only when you install AMD RADEON
HD7450/7470/7570/7670 (where do we find these cards?) graphics card on this motherboard. Use
this to enable or disable Dual Graphics feature. If you enable this
option, the primary monitor will be onboard VGA. If you select
[Auto], Dual Graphics function will be automatically enabled when
you install AMD RADEON HD7450/7470/7570/7670 graphics

ASRock. Please release a BIOS update to recognize the GPU's listed on AMD's box when buying the Processors. A10 Series use the 6670 & 6570. There are no 7570 or 7670 Dedicated GPU's that I can find.

    cards are those activatd (if i can use such word) after installing APU. Depens which one. So now you have option to combine it with 1 of those you see listed on the box your APU came in. FOLLOW VERY CLOSELY INSTRUCTIONS ON PAGE 28 OF YOUR MOBO. Make sure your MONITOR ATTACHED TO MOBO, NOT THE Sapphire HD6670 Ultimate 1GB Video Card, YOU'VE ADDED.
    Again: Follow ASRock mobo instructions (step by step). Hope it helps. Good Luck.
