Pentium 4 Overclocking - 1500 MHz With Asus P4T

Tabula Rasa: Six Boards for the Pentium 4
By

It's the worst of times for overclocking fans. As was the case with its predecessor, the Pentium III, the new Pentium 4 processor comes with a fixed multiplier. Increasing the CPU clock is only possible by raising the system bus clock. Of all the boards tested, the Asus P4T is the most suitable for overclocking. In the test, we used a Pentium 4 CPU with 1500 MHz which we managed to run stably at 15 x 115 = 1725 MHz.
