AMD Dual Graphics option missing, how do I enable it?

*EDIT* Sigh, it can never be easy can it... Sure the dual graphics is enabled now, but both games I've tried (Skyrim and WoW), crash either instantly or within 2 minutes whereas they ran flawlessly yesterday... it has to be related. Any ideas on how to remedy this? Apart from disabling the dual graphics I spent so much time trying to figure out.

OMG! I got it! Turns out somehow my RAM was only running @ 1600, not sure how it got changed in BIOS because I manually put it on 2400 (which is technically "supported" overclock, hope it doesn't make my system unstable *knock on wood*). Anyway, after that I was prompted to turn it on by CCC! So if anyone is having the same issue, you know you have the right hardware and drivers, check to make sure BIOS isn't underclocking/undervolting your RAM (has to be above 1866 iirc), also check under Northbridge settings and enable onboard gfx, as well as surround view/dual graphics settings. Best of luck to everyone who is having issues! Also, thank you to everyone who posted and helped me.



Hello, I recently built a new rig centered around the AMD A10-7850k (Kaveri) CPU/APU. I wanted to play with it and see its capabilities on its own, and I was impressed. However, I wanted more power so I wanted to try out this "dual graphics" thing I've heard so much about.

So I did some research, and it showed that the R7 240 and 250 cards were compatible for dual graphics. I ordered a GIGABYTE GV-R725O5-2GI Radeon R7 250 2GB GDDR5 which arrived in the mail today and installed it (downloaded latest driver, beta version as I was also directed, disabled onboard video and installed the driver package). The new card works great BUT it is not working with the CPU, it is standalone.

The whole reason I bought this card was for the dual graphics capability. Anyway, I did some more poking around and found you should be able to enable dual graphics in the Catalyst Control Center -> Performance tab. Only problem is, My CCC does not have it. I am running the most up-to-date CCC center, as well as the newest driver. What gives? I really hope my card isn't non-compatible or something... Any help in fixing this is appreciated, thanks.

Yeah, if you're trying to use the onboard + a discrete it's pointless to disable the onboard.

You probably read to disable the onboard if you plan to use only the discrete card.

Because I thought that's what you did when you install a new video card, but just now I stumbled upon an old post on these forums that say to enable it >.< I'll have to try that in a minute, lol. I'll post back my results

Well it is what you do, unless you want to use dual graphics :)

Hmm, I re-enabled the onboard and the APU shows up in the display adapters part of device manager, but I'm still missing the option to link the two together for a dual graphics configuration. Should I update my CCC at this time then? Do I need a different driver? I'm confused :/

Anyone else have any ideas? (Just to be clear, dual graphics is NOT crossfire. It is like crossfire except its with certain CPU/APU and certain video cards.)

Seems kinda messy, but here's something: http://www.tomshardware.com/reviews/amd-a8-3850-llano,2...

Here's a guide for Biostar boards, it's probably a similar process for other setups: http://www.biostar.com.tw/app/en/support/faq_content.ph...

Oh wow, this looks harder than I thought lol. This will take some time to figure out I guess. Thank you for the resources, will post back when something does (or doesn't) happen.

Ugh I am at my wits' end here, I have all the BIOS settings enabled that I need, I've tried going from the latest CCC release to 13.12, (I read that it apparently works better), I have dual-channel 2400 RAM (apparently it has to be above 1866 or something), so that isn't an issue either. The entire purpose of my new rig is going down the drain here, lol...
