Components are typically designed with conservative specifications so that their operation is reasonably assured for their expected lifetime.  Overclocking changes some of the normal (safe) operational settings specified by the equipment manufacturer to more aggressive values in an effort to gain better performance.

Bottom line: It is possible to kill components by overclocking if you aren't careful and sometimes even when you are careful.  Realize that you are responsible with this damage, neither the component reseller that sold it to you are nor this site are responsible for the damage.  If you can't afford to buy a replacement, we suggest you do not overclock.

How do you try to prevent damage?

·    Monitor the temperatures and voltages of your system, in particular the CPU .

Programs like MBM5 ( and SpeedFan ( will give you readouts on your temperatures, voltages and CPU speed if you are running a Windows operating system. SpeedFan works with the AMD 64-bit processors.

If you are a Linux fan then try GKrellM ( to monitor your system.

How accurate are the temperatures you're going to see?
Not very good (1C at best) but they are good for relative information related to your system when you make changes. For a little more information, take a quick look here.

    Test, test, test.

Become familiar with your system behavior regarding its temperature and its voltage demands.  When you have changed settings associated with the operation of a component, ensure that its temperatures and voltages are what you expect.
