Help with CrossFire

Catalyst Control Center is the only place telling me I have CrossFire enabled between my two Radeon HD 6770s. That seems legit enough but many other programs, including AMD's own "AMD OverDrive" utility, only report one GPU is installed. Other programs include Piriform's "Speccy" simply stating in the Graphics category "CrossFire Disabled". And as far as CCC goes, when I select the 2nd GPU, i'm not getting any readouts of it (GPU clock, memory clock, fan speed, etc) Advice?
