K53TA Crossfire not working!!?

Sorry if this post is already asked or this is wrong place to ask, im new here

So..I brought this Asus K53TA
but not getting performance as expected!
It has A6 3400M with HD 6720G2 graphic card. (APU)
-------------------------------------------------------------------------
Specs:
AMD A6-3400M 1.4GHz(2.3GHz)
4GB DDR3
AMD HD 6720G2 1GB
Windows 7 64bit
-------------------------------------------------------------------------
So question about Cross fire is.. i enabled the crossfire but i think thats
not the best this machine can do.. so a guy asked me to install this "GPU-Z" software, which will give me details about GPU, which i did!
and when i select "AMD HD 6500M Series" it shows Crossfire enabled
and when i select "AMD HD 6600M Series" it shows Crossfire Disabled!

*Pics Attached*





I dont know if it is normal or not, but this thing is making me uncomfortable!
is this the way it suppose to be?

and one more question is..
what drivers do i install? on AMD site
they have graphic card driver for "A6 3400M" as well as "AMD HD 6xxM
i have both.. what to install?

Thanks in advance..

 

i just bought this same laptop yesterday,and would like to know how this works as well

 

Guys have you looked at this thread?

@georgy95 first take a look at these articles
AnandTech - Mobile GPU Faceoff: AMD Dynamic Switchable Graphics vs. NVIDIA Optimus Technology
To get decent performance you need to Overclock your cpu atleast @2Ghz by than crossfiring would suffer greatly due to higher TDP bracket on APU.
Practical Usage scenario: Oc cpu as stable as you can up to your need
Use 6650 only
Or wait for better Driver (hopefully)

 

its a laptop, so i guess it cant be overclocked much..
is it safe to overclock up to 2ghz?

Actually i cant figure out what graphic card it is...
it says Radeon HD 6500M and 6600M series (6500 or 6600?) with A6 3400M
and on the notebook it written "6720G2 1gb"

so this thing is making it difficult to find drivers, or search problem related to it...

when i go to AMD site to download driver, i get stuck there again
as you can see they have "Radeon HD series" and "A- series (Apu)



when i select "Auto detect and download"
it detects "A6 3400M"

 

The IGP is the 6500, the dedicated GPU is the 6600. A lot of good info on overclocking the AMD Llano and a dedicated GPU can be found in the HP Llano overclocking thread, including how to use crossfire / dual graphics and what are the best AMD catalyst drivers to use.
