The 9600 Pro uses DDR memory, which stand for Double Data Rate, where data is transmitted on both the rising and falling edges of of the clock signal. This effectively doubles the transmission rate making it perform as if it was running at 600 MHz when it in reality is only running at 300 MHz.
So your memory speed of 279 MHz becomes 558 MHz which is only a little under specs.
I wouldn't put it past some third party manufacturer to underclock a card a little bit to get under some thermal or power envelope. Or use a slower GPU and overclock it to near 9600pro levels. Or it could just be reporting it wrong
Knowing more about the machine in question could help answer the question.
