I notice that the Wii U has 4 RAM chips. That means that it is 512X4 as opposed to 1024X2 as I thought before.

If you look at any graphics card (with GDDR5 memory) or RAM sticks (with DDR3 mem.), you will notice that most of them use chips of 256 MB of capacity. Your asumption of 1 GB/chip was a bit... optimistic. And since we haven't seen the other side of the board we can't even be sure if WiiU uses 256 or 512 MB chips.

The Wii U has 2 GB or RAM. It has 4 RAM chips. What more needs to be seen?

I've bolded the answer to your question.

There are more things in the motherboard that we haven't seen, mostly because they probably are on the other side of the board. For example the 8 or 32 GB of flash storage.
