Computer memory is not the bigger the better!

For the upgrading of computer speed, not the better.
Reason 1: computer motherboards support the largest expansion of memory capacity (the motherboard supports memory bandwidth size or the motherboard supports the memory frequency-related, which is determined by the chipset), so the memory over the General Assembly may cause the motherboard does not support.
Reason 2: The larger the memory, the address period becomes long. Because the memory loading of each data has its address numbers, if the memory capacity is too large, this will increase the addressing time of the CPU. Exaggeration For example, a test tens of thousands of square meters of the room as students of their own school to find a corresponding number of seats exam, the exam and so may never find their place.
