If i get 2 kingston hyperx fury 8gb 1866mhz ddr3 ram ( not the kit, seperate rams) can i run them in dual channel? And i have a deepcool assassin cpu cooler so will the kingston hyperx fury fit in the slot?
It might work, but it's not guaranteed. You generally want both sets of RAM to be as well matched as possible. I would just go with a kit. And dual channel kits are often cheaper than buying two DIMMs individually.
