Advantages: Fantastic value

Disadvantages: Need some luck

The best Intel processor to buy is Pentium III 550E. Notice the “E” postfix. It is one of the cheapest Pentium III CPU around, and yet one of the best one. I successfully overclock mine to 825Mhz!!! A real Pentium III 800Mhz cost much much more!!

You need a 150Mhz FSB capable motherboard. The Abit VIA Apollo 133A motherboard is a good candidate. I am using Chaintech 6ATA2. Then you need good RAM. PC133 RAM is almost mandatory. Usually CAS2 PC133 RAM is able to run at 150Mhz CAS3. And as for all overclocking, you need some luck. I would say 70% of Pentium III 550E is able to reach 800Mhz and above. If 800Mhz is no go, then aim for 733Mhz, which is still a good 33% improvement! Keep you finger crossed here.

Ok, with all the gear at hand, set the FSB to 133Mhz, without increasing the core voltage. If 733Mhz is stable, set to the next higher FSB. Otherwise, increase the core voltage 0.1V at a time until the system is stable (do not exceed 1.8V). Usually, 733Mhz is no problem at 1.7V. 825Mhz should be attainable at 1.8V.

Good luck.
