hey guys,

I ordered a refurbished mac pro with 4 gigs of ram.. I ordered 8 gigs of ram for it for a total of 12 gigs of ram.. but upon installing the ram is only detecting showing 8 gigs of ram... I took the original memory out and the system recognized only.. took the 8 gigs out and the system recognizes the original 4 gigs of ram.. The problem is the systems are not recognizing all the ram.. how do i correct this.. both ram sets work....

help.
