Dual Graphic Problem with A10 7850K and R7 250

[prawnsushi]

I want to use my R7 250 with my A10 7850K. However, I can't find any dual graphic option in CCC as well as UEFI. Hope that someone here can solve this problem of mine.

PC information:
Windows 8.1
MOBO - ASROCK FM2A58M-HD+
CPU - A10 7850K BLACK EDITION
GPU- GIGABYTE RADEON R7 250 2GB GDDR5 OC VER
RAM - 1x 8GB 1600
CCC Ver - 2014.0915.1813.30937

Anyone who has the same problem and solved it? Mine sharing it with me?
