On the issue of Pentium D dual core overclocking

Overclocking a computer is to artificially increase the working frequency of hardware such as CPUs and graphics cards, so that they can work stably at frequencies higher than their rated frequencies. Take Intel P4C's CPU as an example, it is rated to work at a frequency that is if the operating frequency is increased to allow the system to still operate stably, then this overclocking is a success.

The main purpose of CPU overclocking is to increase the working frequency of the CPU, that is, the main frequency of the CPU. The main frequency of the CPU is the product of the external frequency and the frequency doubling. For example, the external frequency of a CPU is 100MHz, and the frequency multiplier is , and its main frequency can be calculated External frequency and frequency doubling 100MHz = 850MHz.

You can increase the CPU clock speed by changing the CPU frequency doubling or external frequency. But if you're using an Intel CPU, you can ignore the multiplier because the Intel CPU uses a special manufacturing process to prevent the multiplier from being modified. AMD's CPU can modify the frequency multiplier, but modifying the frequency multiplier is not as good as the external frequency to improve CPU performance.

The speed of external frequency is usually closely related to the speed of the front-side bus and memory. Therefore, when you increase the CPU external frequency, the performance of the CPU, system, and memory also improves.

First look at your motherboard to see if there are 400 533 800 jumpers with a front lift with end bus. If your memory is DDR400, if the CPU is good, you can directly connect to the 800 jumper. The memory is 400 frequency but still can't light up, you may have to add voltage to the CPU (I don't recommend pressurizing and overclocking) If 800 can't be exceeded, you can exceed the non-standard external frequency.

First of all, lock the PCI AGP frequency in the BIOS (if you can't lock it, don't exceed it), and then exceed the CPU external frequency, reduce the memory frequency (if the memory is super low or you don't want to exceed the positive memory) You can understand and then make up.

,Its performance is envious,But it is a more affordable one,P4 series is currently divided into four series of A,B,C,D,file Lu of which A's external frequency 400,B's external frequency 533,C's external frequency 800,D's external frequency 800,In memory usage,They are DDR266,DDR333,DDR400,DDR400。 Therefore, how to make better use of the CPU, motherboard and memory to give full play to the overall performance of the computer is something we should consider. It's like a big horse-drawn cart, a waste of resources and money.

No need to overclock the performance improvement is not noticeable.

It is best to add 1 point and 1 point without imitation of the manuscript, and you must be prepared to take the battery cover, oh ......It's best not to change the octave. At the same time as the frequency increases, you must inject the pin to increase the voltage, and you can't add too much each time, anyway, you can try it slowly to know.
