The 3.2GB is because your Windows is a 32-bit OS and so your computer needs to use some of the 4GB of possible addresses for things like the graphics card and other hardware. Whatever is left over can be used by memory.

The "MAC address" is the low-level unique address of your network controller. I've never heard of a message like that. Perhaps you've made a wrong setting in the BIOS, but more likely you've got a bad motherboard.

I'd contact ASRock tech support.
