Prior to the Pentium II, switches on the motherboard set the clock multiplier of virtually all processors. The clock multiplier defines the ratio of processor speed to the FSB. The other factor controlling a CPU’s speed is the clock multiplier. There are older Pentium 4s that use the 400-MHz bus, but they are being phased out to help increase performance differences between the new Celerons and the Pentium 4. These processors actually transmit data four times per clock cycle, meaning the Celerons are based on a 100-MHz clock (100 MHz x 4 = 400 MHz), while the current Pentium 4 uses a 133-MHz clock (133 x 4 = 533 MHz). These are not straight clock speeds instead they are quad-clocked speeds. The FSB on Intel processors currently ranges from 400 MHz for Celerons to 533 MHz for the Pentium 4. In general, the performance of a computer improves as the FSB speed increases. On most motherboards, the FSB also determines the speed of the AGP port, the PCI bus, and the ISA bus. The speed of the FSB reflects the amount of data that can be sent between the CPU and the other devices in the computer. The first is the interface between the motherboard and the Front Side Bus (FSB).

Even if the processor is able to handle a particular speed, unstable cache memory will feed it corrupt data, rendering the CPU useless. Now, however, all processor caches are attached to the CPU. Changing the way the CPU operated rarely affected the operation of the cache on the motherboard. Older CPUs, like the original 486 and Pentium, had the majority of their cache memory embedded on the motherboard. Today’s CPUs differ from those of the past in that they include on-board cache memory. Perform any modifications to your system at your own risk. This information is presented for educational purposes only. As all systems and components are different, neither TechProGuild nor the author can be held responsible for any damage caused by overclocking your computer. It may also void the warranty on your motherboard and add-in cards. Manufacturers may or may not honor the warranty on an overclocked CPU.

To help you take advantage of your older equipment, this Drill Down will focus on why you might want to overclock Intel’s Celeron and P4 processors, and how to do it.

You can also use overclocking to test the performance of software for future hardware upgrades. For instance, overclocking the low-cost Celeron PCs you bought for backup duty will significantly boost their performance, making them faster and more productive. This equipment is typically already out of warranty, so the risk is often minimal. However, the best business reason for overclocking is that it can make “obsolete” equipment useful again.

Why overclock an Intel PC? The hard-core tech addict answers with the classic “because it’s there.” While poetic, this doesn’t do much for the IT professional who needs more justification to risk voiding a manufacturer warranty.
