A:AnswerDon't buy Asus again and warn your friends. My response from Asus when a key fell apart after five months was "This issue is considered hardware-related, and the manufacturer's warranty does not cover a replacement or refund."
A:AnswerIt’s just one 7500 MHz chip soldered in, and it’s so darned fast it’s faster than old style dual channel even if it might be single channel (and I don’t know which it is, we’re in a new ballgame with all this soldered only memory).
