* Note the actual voltage printed on the CPU label.
For systems with an external clock speed of less than 66MHz
(50MHz or 60MHz), there may be a slight performance
sacrifice for your new CPU. For example, changing to a
K6-166 from a Pentium-75 will result in a system upgrade
speed of 150MHz (not 166MHz). In this case, you can get
improved performance by adjusting the external clock speed
to 66MHz.
