So I bought this motherboard 
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131363&cm_re=M4A79T_DELUXE-_-13-131-363-_-Product
and this memory
 http://www.newegg.com/Product/Product.aspx?Item=N82E16820231225&Tpk=F3-12800CL9T-6GBNQ 
and I just noticed in the manual for the motherboard that supposedly the motherboard only supports either 1 stick or 4 sticks of this memory, and I bought it planning on using a 2 stick config - do you think that the 2 stick config will work or should I just use one until I get the money to buy another set of RAM that supports 2 stick config?
 
Thanks in advance!

I feel like an ass for bumping this, but I really need to know as I'm about to put this sucker together in 30 minutes or so.

Maybe try the tested board? They're pretty savvy over there, being a tech site and all.  
 
I think you should be fine, though. It looks like there are dual channel slots. I don't know the difference between the two colors off the top of my head but your instructions should provide what you need.

Yep, was just about to post it over there too.  Posted here first since GiantBomb generally has more traffic.

First of all, why two sticks when you got a triple channel set? Second of all, the motherboard is a dual channel board. You would be fine with two sticks of memory, but it wouldn't be perfect. And I am pretty sure using two from a triple channel set is even more of a mess.

Well the board you bought performs best with a dual channel kit, which is 2 memory sticks in memory bank 1,3 or 2,4.  You can use more than 2 sticks no problem but it won't be running in dual channel bandwidth mode.

Also, in the future, you should really think about this stuff BEFORE buying. If you aren't super familiar with computers, post your build on the tested forums, or some other computer tech forums, and make sure everything is good. You would have been better off buying a dual channel pair and then another down the road.

You can't use triple channel memory with a dual channel board. You can only run 4 or 8 gigs with dual channel, 6 or 12 gigs with triple channel memory which you don't have for your mobo. Download a compatible list of ram at the asus site and find a dual channel set that's compatible.

You can never use triple channel memory in a dual channel memory mobo. You will have to give up one of them and keep it as spare incase one ever breaks down. I'm not sure if triple channel memory will work with dual channel memory because I never ran dual channel DDR 3 memory before, but out the 4 or 8 gigs, you obviously can't run 6 gigs with three sticks of ram. It's either 2 or 4 sticks of memory for your mobo. Some ppl are saying it might affect your overall dual channel speeds if you added a third stick of ram.

" @HitmanAgent47: He should be able to make them work, it won't work off the bat, it requires some things to be done, but I'm pretty sure he can do it if he finds out how. I don't know exactly how to do it, because I always buy compatible. 
@xobballox: And now you know that it's because if its a 3 pack, it's meant for a board that supports triple channel ram. You might get it to work, but I'm not sure. I would suggest getting in touch with ASUS or whoever your board maker is, and finding out from them. Make sure you have the specific board model and everything when you contact them. And in the future, you should always have someone check over your build. I'm pretty familiar with computers, and I always have a buddy check it over in case there is some new thing I don't understand or I missed something. When you spend that much on something, you should be careful. Also, if it doesn't work, Newegg is great about returns. You can probably return the RAM if you tell them if doesn't work with your mobo, get a refund, and buy ram that is optimized for the type of board you have. "

he can use his triple channel memory no problem,  in theory you can have different brands of memory at the same speed and timings and run them in dual channel mode.   These memory packages are just tested by the manufacturer to work properly in triple channel.    So he could use 2 of the sticks in dual channel since they have same speed and ram timings.   If he inserts that third stick then he'll have to run ram at lower bandwidth which may affect the performance of the system and it wouldn't be running at dual channel bandwidth anymore.
