Overclock your PC without using BIOS
Overclocking P4 is definitely not a walk in the park. Intel has prevented overclocking by restricting the user from changing the frequency of the FSB. Well P4 users worry no more. Here is a freeware which will help you overclock your processor,RAM and PCI.
Keep in mind that overclocking may damage your system.Use it at your own risk !
FIRST download this software CPU-Z. It displays te current configuration at which your processor is operating.
CLICK HERE TO DOWNLOAD
Next Download clockGen. This is the freeware which does the overclocking.
CLICK HERE to download.
Use ClockGen
The main ClockGen window shows available functions on your system, therefore the layout may depend on your system specifications. If ClockGen is able to find a clock generator on your system, the buttons "PLL Control" and "PLL Setup" are present. You first have to select the clock generator (PLL), so click on "PLL Setup".
In some cases, ClockGen will be able to detect the PLL that is used by your system, especially if your mainboard is equipped with an nVidia chipset. In this case, you won't be able to change the PLL model, and you can directly go to the "PLL Control" step.Otherwise, the PLL selection will be set on "Not specified" by default. Click on "Read Clocks" and you will see the registers dump of your PLL in the IC Dump editor part of the window. However, in order to translate the dump into clocks, ClockGen needs you to tell him what PLL model is on your system, using the PLL drop list. If you don't know exactly what PLL is used by your system, we strongly recommend you follow our directives below to find out what PLL model is used on your system.
PLL selection guide
The PLL, or clock generator, consists in a small integrated circuit on the mainboard. There are 6 main PLL brands : ICS, RealTek, Cypress, IDT, Pericom and Winbond. Each of these brands propose a complete range of PLL models, depending on the chipset and on the desired features.The only 100% reliable way to know what PLL model is used on your system is to look for it on the mainboard and notice the chip reference.
Before opening your system make sure that you can do it without making the warranty void !This is the case of most laptops, so DO NOT OPEN them.
Before you get your flashlight, you can try to find your mainboard in the mainboards list below.If your mainboard does not appear in the list or if you can't open your system, you can try to guess the clock generator family with the chipset. Most PLL models are dedicated to a chipset, and knowing the chipset may help to figure out the PLL model family, especially on ICS chips. On ICS chips with a 6 figures name, the model consists in the 4 first figures. For example, the ICS 954148 belongs to the 9541XX family. The following table may help you figuring out what PLL family your system uses.

If your PLL model is not in ClockGen list, or you just know the family of your PLL, you still can use it because most PLLs in a same family use the same registers to set the Front Side Bus. Only GSB/PCI may vary, and you can ignore them :
Select a PLL in the list that belongs to the same family.
Check "Ignore GSB/PCI". Only the FSB will be reported and modified.
Once you get your PLL model selected, click on "Read Clocks", then open the "PLL Control" window. Notice that the number of sliders depends on the PLL model features. Some models also only support a predefined set of frequencies, and therefore may show a "step-by-step" slider.Once your new clocks are choosen, clock on "Apply Selection" to make them effective. If you want to come back to current values, click on "Reset Selection".
The "Clocks" window shows the current clocks in real time. It is independant from the selection window, so it will tell you if the new clocks were really applied.Notice that the CPU clock may vary if the CPU uses a clock modulation mechanism, like C1E or Speedstep. Load your system if you want the CPU to run at full speed.
