Hi all and thanks for reading. I am selling my iXtreme x6618 to my dad so i can build my own pc to which the sith lord has been most helpfull The pc has 4gig of dual ram in it and can handle 8gig max, so as a gift i want to up the ram to 6gig so i will buy 2x2gig modules and keep 2 of the 1gig in there. My question is the slots are blue yellow blue yellow. the ram is dual channel so how best should i put the different modules in example ? blue 2gig yellow 1gig blue 2gig yellow 1 gig or blue 2 gig yellow 2gig blue 1 gig yellow 1gig ? odd question i know but wanted to ask if it mattered. btw the pc has Windows 7 ultimate 64 on it so would handle the 2gig upgrade. Thanks for any advice offered. Vale.
