want to buy RAM for my PC-AMD a10-5800k MSI FM2-A55M-E33 Motherboard But when i checked the specs of my processor it only supports DDR3 1866 memory So do i have to buy a RAM with DDR3 1866 memory type ONLY??
This is what your motherboard supports for ram and AMD would be foolish to make a processor that only supports 1866mhz ram. So the ram listed above is what both the motherboard and processor support, you do not have to be restricted to 1866mhz ram.
