Solution
Your mob - http://www.asus.com/Motherboards/M5A78LM_LX_V2/specifications/

only has 2 dimm slots. So you can only put 2 ram sticks in. so 2 x 2 = 4. If you want more, then buy 2 x 4gb or 2 x 8gb

First, check that you inserted the RAM on your motherboard properly. Then check if you have a 64-bit OS and that the Motherboard supports the RAM memory. The Asus M578LMLXV2 supports DDR3 memory clocked at 1066, 1333mhz and 1600mhz. If these methods above don't work, make sure that the RAM isn't dirty or physically damaged by any means. Also check that the RAM isn;t defective. The motherboard can be a problem if the slots for RAM are damaged. Check the inside of your PC again and notice verything unusual if htere's something like that.

You can try to reinstall Windows, but that may be too risky. If everything is fine, I'm assuming that the problem is that the Windows doesn't recognize the RAM. That is the only explanation. If even that is ok, then you can assume that the RAM is defective. How many slots for RAM are there and how many sticks do you have, apart from your Corsair XMS3. First is, how many slots do you have on your motherboard? Have you tried swithcing places of your sticks? Since it's 4GB,a round number,i'm assuming it's the software that's faulty.

According to your post you bought two sets of 3x2GB which is 6 sticks of DRAM - your mobo, per your designator, M578L M LX V2, only has 2 slots for DRAM, ergo you can only use 2 sticks or 4GB total.....so have no idea what you are asking, saying
 
The only way you get 6 gb is triple channel - 3 x 2gb.If you have 2 of them the you have 6 sticks of ram

The M5A78L-M LX V2 motherboard only has 2 slots to put ram in, not 6 slots. So you acn only put 2 sticks of ram in. 2 x 2gb = 4gb. So you can only have 4gb total ram.
