tried to change it through the bios wouldn't do anything, I do have 4 slots though right now they r in 1 and 3 like the old stuff should I try like 2 and 4? 1 and 2 have white on the ends and 2 and 4 have black don't know if that matters any
i'm guessing your motherboard doesn't support dual channel then. if its AMD socket A or 754 then definitely it won't support dual channel. i know some socket 478 intel don't support dual channel, but a lot do. could just your mobo!
