to give you a rough idea of the difference from a single-channel to a dual-channel is like comparing CL9 1600 to a CL9 1800, nothing much difference at all on most scenarios.

ya like 10 years ago.  If you have a new mobo like that you got ripped off and got some no name crap.  I've not even heard of that problem since ddr was released.

kitamesume:
^ nope, because i've been using 2slot boards from either asus or gigabyte so i've yet to encounter the issue.

Edit: why else do you think manuals still has that "only place the sticks on the black slots first and not the blue slots." or "only place the sticks on black or blues as a pair." instruction? =P

Do note thats an asus X79 board.

NaRu:
Ram is cheap...full that bitch up

kitamesume:
yaaaaa 20$ a pair of 4gbs thats about 40$ for 4slots, or or 80$ for 8slots(on that X79) XD yesh its cheap, wish the HDDs are equally cheap as well =/

There is really no reason to not use dual channels.  If I had a 4GB dimm and 2 2GB dimms of the same speed and placed the 4GB dimm in the first black slot like in the picture from clannad, I would get the same performence from putting the 2 2GB dimms into both black slots.  But, if I was to put one of the 2GB dimms in the first black slot and the other dimm in the first blue slot I would get more performance at no sacrifice.  There is no reason to go out of the way to pick up another ram stick and place it in the same channel.  If you want more ram on the other hand go for it, but at least put it in the other ram channel(the blue slot).

Ill end with acknowledging this.  Does it really matter?  Probably not for most people.  You may only get 1-2 seconds faster decompression of your pirated Photoshop, but ill take it.

I think the issue here is a misunderstanding of what the colors mean. If I understand correctly, you believe that each color denotes a particular channel, while I think that each chunk of two denotes a particular channel, where the colors denote what slots run in parallel in separate channels. In this situation, putting one stick in a black slot and one stick in the blue slot next to it will mean that they end up running in the same channel, while putting them both in black slots would mean they run in parallel in separate channels. I hope that made sense.

Your logic makes perfect sense. There is absolutely no reason why you should not dual channel your RAM when given the option. That, along with the common instructions for users to fill in like-colored slots first, is why I believe you are incorrect in how you think channels are denoted.

For some further proof, take a look at the colors on any six-DIMM LGA1366 motherboard. As you probably know, LGA1366 is known for being triple channel. I have never seen an LGA1366 board with three colors for their RAM slots. There is also no reason for mobo manufacturers to break convention just for a particular socket.
