a double data rate (DDR) front-side bus, (EV-6) meaning that the actual data transfer rate of the bus is twice its physical clock rate. The FSB's true data rate, 200 or 266 MT/s, is used in the tables, and the physical clock rates are 100 and 133 MHz, respectively. The multipliers in the tables above apply to the physical clock rate, not the data transfer rate.
