Answer 1

I'm also sitting with an Arrandale processor, RAM of any type, if only the size of the bar was no more than 4GB. Intel processors don't care about the frequency and voltage, I have DDR3l 1600Mhz and DDR3 1333Mhz right now.
If the volumes of the brackets are different, then first you need to put the smaller one then the larger one
