Hi there all i need some help here with my graphic card
now im running crossfire mode with HD4870
i just bought it a few days ago
but then im running Q6600 3.6ghz

Tried to run 3dMARK06 with my one card i got 17xxx marks
but when i add anew card i thought it will be like 20k marks + but dissapointing score...18k only =.=

Btw guys i wanted to ask about the fps in 3dmark06 usually yesterday i tried to uninstall the Catalyst Control Centre and reinstall again
i tried to run 3dmark06 in normal mode and i got like 110-115fps at the starting
it was increased alot after that i thought it would be better if i overclock i used RivaTuner overclocked to 835/2200 and the fps dropped to 99-104

Anyone have any idea? i tried to reset the core clocks and memory clock back to 750/1800 but it doesn't go back to the 110-115fps again and i tried reinstalling CCC and do it again it worked again...help btw...my crossfire connector are running two bridges

make sure ur Calatalyst AI is enabled

It might be ATI Driver issue too.
