P4 overclocking tool

Due to time constraints we were only able to do run full benchmark suite under Windows 98, but I also added the Linux Kernel Compilation. We have already done a major part of the Windows benchmarks and will supply them shortly. Intel supplied a lot of special benchmarking software for Pentium 4, which we will evaluate, run and publish in the next few days.

After what we have learned in the architectural part of this article, we should expect Pentium 4 to show excellent performance in all benchmarks that are heavily integer based and the ones that take great advantage of the new high-speed bus between processor, system and memory. SSE2-optimized software should obviously run very fast on Pentium 4 as well.

The first is the interface between the motherboard and the front side bus FSB. The speed of the FSB reflects the amount of data that can be sent between the CPU and the other devices in the computer. In general, the performance of a computer improves as the FSB speed increases. These are not straight clock speeds; instead they are quad-clocked speeds. There are older Pentium 4s that use the MHz bus, but they are being phased out to help increase performance differences between the new Celerons and the Pentium 4.

The clock multiplier defines the ratio of processor speed to the FSB. Prior to the Pentium II, switches on the motherboard set the clock multiplier of virtually all processors. Currently, the clock multiplier is locked at the factory. Intel felt it was necessary to lock the clock multiplier at the factory after having problems with ethically challenged vendors remarking the processors with higher speeds and increasing the price.

Check your motherboard Before you begin the overclocking process, determine if your motherboard can overclock processors. The only real necessity is the FSB adjustment, but without the others, your options decline significantly. Overclocking will require your motherboard to give orders to the CPU. This is not its normal mode of operation. If you have a computer that came from a major manufacturer like IBM, it's likely that your motherboard won't provide any overclocking abilities.

Even among aftermarket and consumer-level boards, overclocking opportunities aren't guaranteed. Component capabilities Bear in mind that if you have a processor capable of a percent or more speed increase, it's unlikely that your video card or memory will enjoy running that much faster. Memory speed Memory speed is often tied to the FSB, but there are boards that will lock the memory bus speed. Half the performance increase you may see from overclocking a CPU comes from increasing the speed at which the processor can talk to the memory.

High-speed memory abounds in the market for DDR systems, which constitute the majority of computers out there. Power needs You'll need to know how much power your processor uses. Use too much power and you could burn out your processor. A mere shift in the manufacturing process can change the operating voltage of a CPU by a significant amount, so I don't recommend running a processor at a voltage more than 10 percent above what is listed for your type of processor at the new speed.

Even then, you're relying on the engineering design overhead, which is not something for the faint of heart. Individuals bent on squeezing out every last iota of performance can boost the voltage, but those who prefer long-term stability should only do so for testing. This is also the best time to check the power supply in the system you intend to overclock. Speed requires power, and unstable power inevitably leads to unstable processors. Intel processors are hungry beasts, consuming 40 to 75 watts of power.

Your graphics card may take another 50 watts of power. After saving the profile, a file will be automatically created OverdriveNTool. Sample text in OverdriveNTool. You can view saved profiles directly in the OverdriveNTool. To automatically download the desired overclocking profile of the video card, create a batch file batch file with the following text in this case, to use profiles 0,1,2,4,5 for video cards with the same numbers :.

To restore the video cards after failures in old versions of the program, you had to add the -r command to the BAT file to reset the GPU settings to the default values: OverdriveNTool.

Where the number indicates the number of the video card with respect to which the reset is performed. The batch file for automatic launch in old versions of the utility looks like this:. How To Overclock a Pentium 4 Processor Level of difficulty: Intermediate Overclocking is a process that allows a computer to operate faster than the specifications provided by the manufacturers. The success in performing an overclocking would usually depend on the quality and brand name of the components with some brands of hardware overclocking better than the other brands or models.

An update of every computer software and drivers including critical operating-system updates must be performed.

Step 3 Download a program that will monitor the computer. The user can download a free program known as FreshDiagnose or try to visit the PCPitstop website to execute diagnostics.
