What you should know before Overclocking Cont'd

Tweaking and Tips How to Maintain System Stability

Please note that no two semiconductor chips are the same even at the same clock speed, for it's impossible to make it so. Thus all processors might not be able to reach the same levels of performance certain other systems based on the same processor might reach, and some might exceed expectations.

Since the CPU will actually be working much harder than it's supposed it might need more power for stable operations. Thus a slight increase in the core voltage of the processor might be necessary for successful overclocking. But please note by doing so you risk permanently damaging your processor if done incorrectly.

Increasing the Bus Speed might cause certain other devices connected to the system bus such as Sound cards, VGA cards and hard drives to become unstable if they're not designed for the higher bus speed. You should most probably decrease the mode of your hard drive (Such as from Mode 4 or Ultra DMA 66 to Mode 2 Ultra DMA 33) if your hard drive becomes unstable.

Core Voltage Tweaking and Tips

A processor consumes power when engaged in its operation and the core voltage decided the amount of power a particular processor consumes. Since Overclocking will make the processor operate at a higher clock speed it will need more power to do so. (Logically speaking). Below is a list of default core voltages in some processors. Thus it might be necessary to increase the core voltage slightly to achieve a stable overclocking.

However be very careful in doing so and increase in small percentages as too high a voltage might destroy your processor. You may do this by adjusting the jumpers or dipswitches in the Motherboard (refer to your manual) or by software core voltage control a function certain Motherboards provide in its Bios. Please note however ALL Motherboards does not allow you to manipulate the core voltage as it is dangerous and detects it automatically. If this is the case you will not be able to manipulate the Bios. For the Bold hearted, Tom's Hardware has posted an article on how to break this protection as well.
