So i have a ddr3 ram which is team Group.Inc and Kingston. Both are the same speed and 4gb. my question is that why is my newly bought ram not reading and when i check my installed memory is says 8gb but only 3.42 usable. And then i checked memory diagnostic it says hardware problem so it may seems that my newly bought ram is faulty so i refund my ram with a new one and it still says hardware error anyways can some one help me im new to this stuff and i thought i can make my pc faster by my own.
