First, it is necessary to download SetFSB for Windows and start the application on the computer. Users are to find out the model of the clock generator for a correct configuration. One can find such information on the processor chip, but what concerns laptops the procedure is quite complicated. It is much easier to visit the website of the manufacturer and find out the installed model. Therefore, the user is aware of the model of the clock generator and the program is started. The next step is to choose PLL value corresponding to user’s model.
Users need to test the generator to determine the current clock frequency. In the application window, one clicks the Get FSB button. After a short test, the current value appears in the Current Frequency line. In the field Select Frequency there will also be displayed the frequency value and both indicators will be still the same. The second field corresponds to the new frequency that users are going to set.
Choose the clock generator which corresponds to your computer’s motherboard. Select the “Get FSB” button. After you do that, the program shows you the frequency of your PCI device, AGP device, DDDR device, and FSB device. The dedicated sliders let you adjust these values to what you want them to be.
The system parameters must be monitored consistently and carefully, including the processor frequency and temperature. Also, a diagnosis can be conducted that includes a forced alteration of the SMBus register and PLL register.
Changing the frequency of the clock generator
To perform the simplest actions in the program, there is a special slider below the selection field for the frequency value. Moving the slider in the necessary direction users either increase or decrease the current indicator. It is not advised to increase the value of the current frequency to a large range at once. Such an action may affect the processor negatively and cause its damage.
Thus, the shift of the slider for a safe change in frequency should not exceed 15 MHz, they say 20 MHz is maximum. Users can use the activation item Ultra to access advanced settings. Advanced settings should be used only by experts. Having completed the setting procedure, users save the settings of the necessary option value using the button Set FSB.
It is strongly recommended to monitor the temperature indicators of the CPU and its cores after the changes in the value. In case of a critical excess of the accessible threshold it is possible to reduce the frequency and temperature. Otherwise, the processor simply burns out. That is why such precautions are necessary. Users can use a CoreTemp utility for this purpose. CoreTemp is a powerful program to monitor processor temperature.
It can display a temperature of each individual core of every processor. In addition, users are able to observe temperature fluctuation in real time with different workloads. There are also programs with advanced features such as AIDA64. The main thing is if the applications show peak loads exceeding at least one indicator for one core, the frequency should be reduced. It is also essential to remember that the reduction should be in limited steps, it is not recommended to reduce immediately the whole range to the original values.
The system requirements to download SetFSB is Windows XP and above. The great thing about the utility is that it does not change the voltage. This ensures the security of computer components. At the same time users should be very precise while working with the program; in case the frequencies are too high, it may cause great damages.
