Phenom x4 925 memory speed issues

the frequency is 667 and when run in dual channel you get 1333mhz

Your memory is running at the appropriate speed. It transmits on the rising and falling side of the clock cycle so while the clock is running at 667MHz it transmits data twice as many times during that second so the data speed is 1333MHz, so the data rate on any DDR is always double the bus clock rate, hence the name DDR(double data rate).
