Can old CPU be overclocked

[Memnon]

I have old CPU's and need to overclock them. I have a old AMD k5 pr166 which i want to overclock.

Try changing the clock speed of your motherboard.......

Try the following procedure it might help you but do it on your own risk....

• Enter the BIOS during system startup >>> Bios Features Setup, CPU Soft Menu or any other similar option and press Enter.
  
• Modify the CPU Host Bus Frequency, External Clock (PCI) or similar option shown, do it using the Page Down until you find the motherboard FSB speed you want.
  
• In the CPU Core section find the Multiple Bus Frequency or Multiplier factor and modify the value of the CPU Multiplier. Now save the changes to the CMOS and exit.
  
• It is generally advisable to change the parameters in steps. For example increase the FSB speed by a few MHz and check whether the system boots.
  
• If your computer boots increase the speed further and check again.
  
• Repeat until you have the highest setting with which your computer will boot up.

After following the above steps check the performance of your OS by using some resource hungry application to check whether the system crashes. If it crashes lower the FSB speed in steps till the point where the system is stable.

Overclocking results in change to the voltage profile within the circuitry. This can be minimized by increasing the voltages applied but too much increase can burn up the circuitry.

A bigger problem is the heat generated due to overclocking. This is tackled through the use better CPU heatsinks and fans, heat spreaders on memory, fans on video cards and case fans.

again would like to mention "Try at your own risk"

Not a bigger difference will be found if you overclock it....
