Guys help me please sorry if this is a noob question, I have my old pc . and put another video card crossfire it to improve gaming performance ( 2 x Gecube hd 4850 512 mb ). here’s the specs:

Operating system: windows xp professional x64 edition

Amd atlon 64 x2 6000 3.0ghz

Asus m2n-sli 560 sli

4 gig 2x2 kingston ddr2 pc 800

Gecube hd 4850 512 mb
http://www.shopbot.com.au/pp-gecube-radeon-hd-4850-512mb-gc-hd485pg3-e3-price-116753.html

My problem is when I play games as if I can’t feel the improvement. So heres my questions:

1. How would I know if crossfire is running?

2. How could I improve the cooling ? cause when I play games the temperature reaches 80 to 90C.

3. Then I try to enable the manual fan control and set it to 75%, and still too hot and too loud. Plus when I reboot the pc. When pc starts to boot again, I don’t hear the fun running at 75%.... you need to open the catalyst control center again to activate the fan speed to 75%.

Any help would be much appreciated

When you restart your pc the fan will spin based on its temp, not what ever you put on CCC.
you have to enter CCC and select the crossfire tab and activated, the screen will blink for a few secs and and thats it. You can right click the CCC icon on the task bar and select the 1st 4850 and you will see an option to show you when Crossfire is active.

you should see an ati logo on your screen, and also crossfire only works with fullscreen.
