Lga 775 socket enquiry

[Nashsafc]

do lga 775 sockets run ddr3 ram? Because looking at a friend's cpu-z it shows ddr3 ram for an ddr2 motherboard this can not be right?
This is what i read from his cpu-z

Of course they can. Core2 CPU's have external memory controllers. The motherboard manufacturers can build whatever they want on their boards.
