Why is all my extra RAM marked as “hardware reserved” in Windows 7?

I accidently plugged DDR2 into my DDR3 motherboard. I have 4GB of RAM, and it was running all 4GB before my accident. After removing the DD2, Win 7 64-bit started doing the Hardware Reserved nonsense.

I have a AMD CPU HDZ955FBGMBOX Phenom II X4 955 Black Edition 3.2GHz AM3 125W.

Could I have shorted out the channel?

This question might help. The answer follows:

Turns out that the installed RAM was in an unsupported config -- On this machine, if you install 2GB chips, they have to be installed in triple, as referenced here (pdf).

Its interesting to note that Windows saw the memory, but it was rendered not usable and marked as "hardware reserved".
