Triple channel....

So according to this article triple channel memory is not that benifcial.

So what i wanna know is, does an i7 motherboard/cpu require "triple channel memory" or can you put any thing in. Like 4gb of DDR3 RAM, dual channel i suppose.

So if you can do dual channel, im guessing you can as the article did (but if someone could clear it up for me), then why should i spend £119 on DDR3 RAM which costs £65 early last year. I should just got for a fast DDR3 dual channel set right?

Dual and Single-channel work fine, Intel's own X58SO board has 4 DIMM slots so you can go triple/dual.
