I have over clocked my systems by a few hundred megahertz at the most in the past. How do I over clock by over a gigahertz ? I have the cooling, I know that raising the multiplier and the voltage are the key ingredients to a good over clock. I don't want to just take a stab at it and make the system unstable. I would appreciate some info, if info is needed on my end in regards to BIOS settings etc I can supply this information. :)
Some information on your hardware would be beneficial for us to be able to assist you with this. Before you start, you should return your system to its default settings and clock speeds and make sure that it runs stable. If it isn't stable at the default, then it is very difficult to ascertain whether it is stable when overclocking.
The actual overclocking limit depends on the hardware in your system. Bear in mind that not all systems take to being overclocked, and even successive motherboards coming off the production line can have different abilities in this area due to, for one thing, component tolerance. Processors too come into this category, and even those that come off the same manufacturing die can have different overclocking capabilities.
As you know, overclocking means running components at a faster speed than what they are rated for. This increase in speed leads to an increase in the amount of heat produced. For moderate overclocking, such as 2-300MHz, the existing cooling should be sufficient. However, when overclocking by a significant amount, better cooling needs to be employed. This is usually liquid based, and you should read and follow the instructions supplied with the kit on how to attach it to your system.
One thing that you might need to do when overclocking is to adjust the voltages, usually upwards, by small amounts in order to maintain stability. This too increases the amount of heat produced, hence the need for improved cooling.
Having said all that, a lot does depend on your hardware and its original clock settings. An overclock of 2-300MHz is reasonable for many systems, but when going for a 1GHz+ increase it is a totally new ball game.
It might be beneficial to visit the forums of your motherboard manufacturer and see what luck any other users have had in overclocking with identical hardware to yours.
