As I understand it, you increase the bus speed.  If you have, say, a 50MHz
bus and a 150MHz clock-tripled processor, you might increase the processor
speed to 200MHz by increasing the bus speed to 67MHz.

As I said, the whole system (meaning: everything that takes its timing from
the system bus clock).
