I've been trying to find out why this is happening for days. I'm on the A8 APU Notebook Vision quad-core, dual radeon graphics setup. My first graphics card, the 6620G, is working fine and shows memory usage on both the AMD System Monitor and the AMD OverDrive program. However, being dual graphics I have a second graphics card. The 7450M, shows no memory or work being done. For instance, when I am playing a game, upon viewing the AMD System Monitor, regardless of graphic level on game, all the work is being done by my 6620G. The 7450M doesn't show any signs of work, infact, it actually says it has 0Mhz of memory throughout. How come my 7450M isn't exactly being recognized?

More information:

I have crossfire enabled. (through AMD vision control center)
This is a notebook PC.
When I check device manager, it doesn't show any problems, and also on the AMD Vision Control Center, under "Hardware" (under information) my second graphics card comes under "linked adapter", and shows that in fact it does have 900 MHz memory clock, which in AMD System Monitor it said it had 0MHz.

I have looked everywhere on the internet for a solution, if I get no replies on this thread I shall be calling AMD or emailing them myself.
