Thank you, Al Hill for your contribution.
..Ralf.., as Doc mentioned, the memory configuration is determined by the motherboard you have, what I can tell is that the processor you have supports up to 32 GB DDR3 at 1066 MHz or 1333 MHz (per the specifications shared by Doc).
I hope this information helps.
Please don't hesitate in contacting us back if you need further assistance.
