Asus P5KC + Crucial Ballistix DDR2 PC2-8500

hi guys, i've been having trouble getting the actual speed of my memory (1066Mhz) to work with this motherboard, i understand that Crucial isnt in Asus's "Qualified Vendor's List" but im hoping that there is a way to work this out.


any help or tips appreciated, I apologize if this is redundant but i've searched and didnt find this specific case.

thanks
