Everytime I dod dual channel my comp doesnt boot at all, nothogn shows up. when i put it back its fine. My P35 mobo supports dual channel and my RAM says in big letters DUAL CHANNEL!. am i missing a bios setting or sumthing? andi put it in the way the mobo tells me to.

Test the memory and slots. Can you boot up with each memory stick by itself? Can you boot with a single stick in each slot? When you say you are putting it in the way the MB tells you to - does that include putting it into the specific slots that it tells you to use?
