- Actually, the internal data bus on the AMD 5x86 has been widened to 64
- bits, but you are right, it has been clock-quadrupled to 133 Mhz, and
- the performance appears to be close to, if not right at P90 speeds.

- I've recently heard that people who have good warranties are trying to
- increase the speed of some of the motherboards even more. They are
- setting a jumper on the board to change the board speed from 33 to 40
- Mhz, and that in turn, make the CPU run at 160Mhz. You'd probably
- need a better fan after that. Norton SI scores run over 200 now. I
- just might try that myself...
