I have a P4 2.8 Pc that has two 256 DDR modules. The system seems to have problems running games and so on. When the DDRs are installed next to each other on the motherboard. But if I install them in spot 1 and 3. The system seems to be fine.
I am not really sure why this is both DDRs are the same type but by different manufacturer?
Am I putting the system at risk not installing the memory side by side?
