Bought 4x4gb sticks of ram a few months ago and since my computer has been restarting randomly, without any noise or warning. Today i took out each sticks and tested every slot one by one and every sticks as well separately. They all worked perfectly, but when I put all four together, restarts again, one solution i found was to underclock the ram when 4 sticks are present.
