RAM only showing half capacity

I just noticed recently when I looked at my computer's properties that I only have 8GBs of RAM. I'm not sure why the other half is missing, but I know for a fact I have two separate 8GB sticks of RAM installed (It says 8GB's right on the RAM). Here's the exact RAM:
http://www.corsair.com/en-us/vengeance-8gb-dual-channel-ddr3-memory-kit-cmz8gx3m2a1600c9

I've tried tinkering around in bios to adjust the frequency and voltage, but that hasn't worked. I tried going into msconfig, advanced boot options, and the box there is not checked for memory limitation. I've tried swapping them from dimm1/3 to dimm 2/4 and I've also tried booting with only one RAM stick, which is how I came to realize it's not one faulty stick or dimm slot. For whatever reason the system is only reading each stick at 1/2 it's actual capacity. I've been digging around for awhile now, but I can't seem to find a definite answer. All memory checks have come back good.

I started to think it might be a limitation of my motherboard, but the documentation says it can hold up to 32 GB and there's only 4 slots, so with some basic math (I could be wrong) I put that at 8GB per slot.. precisely what I have right now, but only 2/4 slots filled.

Here's some basic specs I feel are most relevant to the issue:

Motherboard: MSI P67A-G45
RAM Corsair Vengeance: 8GB (x2)
Windows 7 (64bit)

"I know for a fact I have two separate 8GB sticks of RAM installed"

He has 2 sticks of 8GB, he would have 4 sticks if they were 4GBx2

It has been so long since I bought the RAM that I can't even remember how much I originally intended to purchase anymore, but ShadeTree might be right. Each stick says "8GB" on them individually, but looking up the product code comes up with that web page that says it's an 8GB "kit." I still think each stick should say how much is on THAT stick, not the kit. I'm still a little confused about this, because common sense would dictate that the RAM stick would have the amount memory it says. What if the two sticks get separated? It's too easy to get them mixed up and seems like a huge oversight from a manufacturing perspective. Does RAM always come like this?

Actually I'm just a retard. It did say 8 GBs, but in parenthesis it has (2x4GB) and clarifies 4096 MBs. When I first looked at it I guess I didn't look closely enough. Sorry to waste everyone's time!
