My bios says that my cpu is currently using Single channel memory. With that in mind I'm pretty sure it is still utilizing both RAM sticks. Is there a way for me to change it from Single to dual channel?

Also I know That I probably won't need more memory.. But if I found really cheap memory on sale, does it HAVE to be the same brand/model as my current memory? Would I be able to just add more RAM to the 3rd and 4th slots?

Thanks! :)

    look in your motherboard guild for the ram. the ram has to be in a0 and a1. most times there the two of the same color slots. if you put them in the first two then you have one stick in a0 and one in b0. with ram it the speed..voltage and timing of the ram kits. also the ram kits should be on the mb tested list. myself i would not try to save a few dollars for a cheaper kit i would use 4 match dimms.
  2. Sorry, What do you mean by the "mobo guild"?
    Could you also clarify if it should be in a0 and a1 or.. a0 and b0
  3. there should be a cd with the mb on it is the mb layout guild and cmos setting guild in pdf form. it also on asus web page. it have a photo of the mb and the ram slots and the guild to install the ram. if your mb is laid out like my asus mb is it laid out as a0 b0 a1 b1. the same banks are the same color.
  4. i think he means mobo "guide"
  5. thanks
