Take a number of important steps before overclocking.
- Check if an operation system is stable in its normal mode. There is no reason to overclock the computer which is inclined to failure or hangs in its normal mode as overclocking would only escalate the situation.
- Find out all parameters of BIOS which are necessary for overclocking and learn their function. These parameters may vary for different motherboard models, so you should learn the manual for a particular motherboard.
- Learn the way of BIOS zeroing for your motherboard model. This is necessary in order to reset BIOS settings in case of unsuccessful overclocking.
- Check working temperatures of the main components and their cooling. To monitor temperatures, you can use diagnostic utilities from the CD to your motherboard or the programs by independent manufacturers: EVEREST, SpeedFan (almico.com) and other. To make the cooling better, perhaps, you may need to change a processor cooler to more powerful one and also to take steps to improve the cooling of chipset, video adapter and memory.
- Appreciate the opportunities of your power supply and change it to more powerful in case of necessity. The computing power increases during overclocking, so there might not be enough opportunities of your power supply.
