Was looking to upgrade the RAM in my desktop which is using a Athlon II X4 630. According to Newegg the CPU is designed to run in a AM3 mobo but my system says that my mobo is a 780g variant which is a AM2 mobo. So I'm a tad confused right now on whats true. (The system was originally a Dell Inspiron, but I upgraded the PSU and GPU two years ago to play some games which is why I don't know the maker of the mobo).
