I recently came across an interesting question that I couldn't answer due to my limited knowledge in the field at present. Before I get to the question, I do understand that Motherboard RAM is not GDDR, this is a question of theory. Suppose I have a Single CPU on a motherboard. Would it be working harder if used in conjunction with GDDR5 ram vs DDR3 Ram? Whatever the answer is, could you provide an explanation please. This is merely curiosity.
