>1. To have dual channel memory do you need two separate>memory sticks?Yes. And the memory sticks must be of exactly the same model. You should allways buy the memory sticks as a pair (matched pair).>2. Is there a noticeable advantage to use dual channel memory>in FSX?Don't know. Have never tried using unmatched pairs of memory modules. Maybe some hardware expert like Nick might help you out on this one.Ulf BCore2Duo X6800 3.3GHz4GB RAM Corsair XMS2-8500C5BFG 8800GTX, Creative SB X-FiFSX Acc/SP2, Vista 32
