  1. Heya, I'm new here, recently, my friend said I had a computer that could have a "dual DDR channel"? I dont know much about computers, and i wanted to know more, so he checked my computer with a program thats called "Cpu-Z" and it said my DDR channel was Single, even though all my "RAM" slots are filled with DDR 512mbs, any reasons why?

    Well there may be a setting in Bios to set it for dual channel
    Or even a little jumper on the Motherboard that must be placed on the correct pins

    You will need to download your computer's (or motherboard's if it's not a name brand) Manual

    Cool, thanks for the info, tho ive looked into it and all with my friend, we read the manual and found out what we needed, yet even though we followed the instructions, its still single. It said we needed the same number and density, but my computer has all 4 slots(2 blacks 2 blues) filled with 512mb RAM, is there something to do with that "bios" u mentioned eariler?

    edit: wuts a jumper?

    All the ram has to be identical. Your mobo may also require it to be of a certain type.
