66 (more specifically 66.667) megahertz (MHz) is a common divisor for the
front side bus (FSB) speed, overall
central processing unit (CPU) speed, and base bus speed. On a Core 2 CPU, and a Core 2
motherboard, the FSB is 1066 MHz (~16 × 66 MHz), the memory speed is usually 666.67 MHz (~10 × 66 MHz), and the processor speed ranges from 1.86 gigahertz (GHz) (~66 MHz × 28) to 2.93 GHz (~66 MHz × 44), in 266 MHz (~66 MHz × 4) increments.
Route 66 was a popular US television series on
CBS from 1960 to 1964.
