Prerequisites For Successful Tuning
The basis for successful overclocking is an Asus A7V with an additional DIP-switch for changing the clock multiplier. Lately the manufacturer puts this switch on current board versions.
A few conditions must be met before an AMD Athlon or Duron can be pushed to its limit. First you need an Asus A7V that has the additional DIP-switches for adjusting the clock multiplier.
There are two possible scenarios: If the board is already equipped with the DIP-switch quit works, no further action is required. If the DIP-switch is missing, it must be added besides two other components - as described in the article Modifying An Asus A7V Motherboard For Duron-Overclocking .
The processor that is going to be overclocked must also meet a few requirements: The L1 bridges on the ceramic body of the CPU should be closed. If they are open, you can use a pencil to close them.
The voltage controller of the Asus A7V resides on a separate circuit board. It generates a standard maximum core voltage of 1.85 Volts.
