Hello everyone I'm slowly building my third computer and my first time
with an Asus Motherboard. I want to install the following parts to this
motherboard: the Corsair 650TX Psu, a LITE-ON Black 12X Blu-ray Burner
with Blu-ray 3D feature SATA Model iHBS112,I already have a WD 120GB HD
+ a Maxtor 200GB HD an I intend to get a 1TB to put in later on.I'm not
sure if I want to put in a video card or not because I'm connecting the
computer to an HDTV thru HDMI,I'll get the video card if I can run both
the onboard HDMI along with the HDMI on a video card.and I hope to get a
26 inch LED LCD TV to run it on. I'm not a gammer so I probably won't be
getting the crossover or SLi hookup.And I'm thinking of getting the
NZXT Tempest case because of all the fans in it to keep it cool not that
I'll be over-clocking but I like my computers to run cool. Can someone
please tell me what's the difference between triple and dual channel
memory because I want to run either 6GBs or 8GBs of ram in my system and
maybe later on I'll get the ASUS 24x DVD Writer SATA Model
DRW-24B1LT/BLK/B/AS LightScribe Support - OEM to go along with my Bluray
burner also a wireless N USB adapter.

"Can someone please tell me what's the difference between triple

Your motherboard and processor support dual channel memory.

http://www.newegg.com/Product/Product.aspx?Item=N82E16813131627

There are four RAM slots. A natural expansion order, would be
to start with two sticks of RAM, and increase later via two
more sticks of RAM. You could buy dual channel memory, because
that would give you two matched sticks per package.

Triple channel memory would come with three sticks in the package,
which would mean purchasing a fourth, unmatched stick later, to
fill the fourth slot. Installing three sticks would be a non-optimal
configuration for your system. Your system works best with memory
added in matched pairs. (Mainly, because if you need to sell
the memory later, it is going to sell easier as a matched pair,
than as individual sticks.)

The user manual for your motherboard, notes that the AM3 supports
Flex Memory (to borrow an Intel term). You *could* use three sticks.
You could use 2x1GB on one channel, and a single 2GB stick on the
other channel. (Matched quantity on both channels, gives dual
channel operation.) But there is no particular reason to be buying the
RAM that way. You would not typically go out of your way to do
it that way. You could start with 2x2GB, and add a second 2x2GB.

Always check the vip.asus.com forum, for your motherboard, to
see if other users are having problems with the RAM. For example,
this person seems to have an incorrect VDimm setting, as his
memory is running hot. He decided to buy triple channel memory,
but that would not be my choice of ways to go about it.

You would buy regular memory, at 1.50V to 1.65V or higher, rather than
the 1.35V memory which seems to be intended for some Intel systems.
At least, I don't see any AMD systems in the list here.

If you install 4GB or more, to make the best usage of the memory,
you'll need a "64 bit OS". This is due to an artificial limitation
in Windows as to how much memory a 32 bit OS can support.
