Intel how to super fare multiply the voltage

First, the subject is different.

1. External frequency: the working frequency of the system bus (system clock frequency) and the frequency of data transmission between the CPU and peripheral devices.

2. Super frequency doubling: the output signal frequency generated is an integer multiple of the input signal frequency.

Second, the characteristics are different.

1. External frequency: By increasing the external frequency or frequency doubling coefficient, the microprocessor can be made to work at a higher clock frequency than the nominal main frequency.

2. Super frequency multiplier: It is to make the system bus work at a relatively low frequency, and the CPU speed can be improved by frequency doubling.

Third, the role is different.

2. Super frequency doubling: Fourier series is adopted. Each periodic signal can be defined as the sum of a fundamental frequency and its harmonic parts.

The main frequency of the CPU = the outer frequency x the frequency double, whether it is super external frequency or frequency doubling, the CPU frequency can be increased. However, they also have differences:

CPU external frequency, is the working frequency of the system bus, is the frequency of CPU and peripheral equipment to transmit data, if the CPU external frequency is improved, then the interface frequency of memory, hard disk and other equipment will be improved, these devices are likely to be unable to work normally at such a high frequency, so the current CPU is locked in the external frequency, can no longer be exceeded.

CPU frequency doubling refers to the CPU working at a frequency several times that of the external frequency, the smallest unit is, currently overclocking can only be achieved by adjusting the frequency multiplier.

1.Not all CPUs can directly increase the frequency multiplier, and most U are locked multipliers.

2.It seems that after overclocking, at the same frequency, the actual performance of the super-frequency is higher than that of the super-doubler, and I don't know the specific reason, you can check it online!

Except for the CPU of the black box, everything else is locked to the external frequency, which can only be over-doubled, and then manually reduce the frequency of the North Bridge.

And the performance of the super external frequency has been improved even more significantly.

Because the frequency is not all tuned... And some people just want to make the memory higher---

There are two types:

The frequency doubling is locked, because the CPU comes with turbo frequency and energy-saving functions, so when the processor is not fully operational, in order to accommodate energy saving, the frequency doubling will automatically reduce the frequency, this situation does not matter, when the CPU runs a large task, the CPU frequency doubling will go up.

The frequency multiplier is not locked, and the frequency multiplier is lowered when overclocking, so you need to set the BIOS to increase the frequency multiplier.

Steps in BIOS to increase the frequency doubling to achieve overclocking:

Press del on boot to enter ASUS's EZ BIOS;

Click Advanced Settings in the upper right corner and select the overclocking column;

Taking i5 3570K as an example, the CPU is locked at 100MHz, and the frequency doubling design is not locked.

In the process of pulling, there is a CPU running frequency value display on the interface, which will change with the change of the frequency doubling value, as a reference, the value is about 4500MHz, exit and save, and see if it can enter the system;

If you can't, go into the BIOS again and add the CPU voltage, add a little! Exit saving. Re-enter the system, can not enter, and then pressurize until it can enter the system and pass the oven software, and the voltage cannot exceed the safe voltage.

The voltage can only be added little by little, so don't be too troublesome. When the voltage is very high and the system cannot be stabilized, it means that the CPU constitution is not good, and the frequency can only be reduced.

Overclocking the power supply burns the computer.

The power supply can't be overclocked, but there is a next peak and a trough. It's the rated power and the actual power!

Overclocking is an operation that the CPU motherboard and graphics card work together, and one thing alone cannot be overclocked.

Do you know what frequency is? The power supply should be increased.

The higher the multiplier, the better;

This is not the case, because the current Intel CPU, which is not at the end of K and X, can only be super-frequency, but the super-external frequency is currently only possible with the 6th generation of the non-K with the BIOS version of the older Z170 or other chip motherboards with clock generators. The theory is that the higher the better, but when it comes to a CPU, how much it can exceed depends on the physique, not how much you want to exceed.

With K plus voltage over-doubled! If you don't have K, you can overshoot the external frequency a little, but not too much! So it's better to buy a U with K for overclocking.

The external frequency is better The external frequency is better to add one at a time, otherwise it is easy to explode the frequency doubling depending on the physique and voltage.

The octave is generally locked, so it is super-frequent.
