To run memory in dual channel both sticks MUST be on same colors?
In the K9N Platinum booklet it says that place 1 stick in DIMM 1, then place another stick in DIMM 3 to run in dual channel... I asked my friend he said both must be in same color DIMM.
Also is there anyway to make sure I'm running in dual core through some software? Like CPU-Z? Will that tell me if I'm running in dual channel for sure?
Follow the motherboard manual. Usually for dual channel to work both banks (like 1 and 3) must be populated. Your BIOS information screen as the computer boots should note if you are in dual channel mode or not. CPU-Z will only tell you on the Memory tab if your RAM is dual or single.
Jsut stick 'em in the same colours and you will be fine, trust me.
These things I know, just be shure they run at the same speeds
Obviously you don't know what you are talking about. Don't give him advise if you haven't checked it first. DO NOT USE TWO IN THE SAME COLOR, follow the manual which calls for slots 1 and 3, they are different colors.
