Macs are kinda fussy about the Ram they like. You are sure that your Mac can handle 16 gigs of ram fine, correct? You seem to have the correct type of ram for your machine, so no problem there. You might have got a bad stick of ram, by all means swap it with a known good stick of ram and see if that fixes your problem for right now. Apparently most MacBook Pro's can handle 16 gigs, so that's possible. You could try resetting the SMC and zapping the pram, how to do that can be found on Apple's support website or you could google it.
