Force Crossfire on 6450s

post #1 of 2
Thread Starter 
I have two AMD 6450s 512mb cards and am unable to crossfire them. They are produced by HP (HP (103)) and do not have a bridge. Is there any way to force them to crossfire? I'm sure they would not run into bandwidth issues on a 16x and 4x lane, so the bridge shouldn't be needed. Also in GPU-Z Crossfire is showing as an option but displaying as disabled. In CCC there is no option to enable crossfire.

I'm trying squeeze some more performance out of these two in a simple 3 monitor setup-not for gaming.

Thanks

Why do you need more performance for a 3 monitor setup not used for gaming would be my question? I believe some of the (very old) drivers allow CF without using a cable, but those should be more than enough to run any configuration you could need on 3 monitors that you're not gaming on.
