Is it better to lock the CPU lock screen or not to lock it Please ask everyone Thank you What does t

It's good not to lock. Frequency locking refers to limiting the maximum operating frequency to a higher frequency that cannot be overclocked to a higher frequency with the help of software methods for faster running efficiency.

In Intel's CPU, the last letter is generally seen, and K stands for the processor that does not lock the frequency multiplier; M stands for standard voltage CPU is removable; u stands for low voltage energy saving and can be disassembled; h is high voltage, is welded, can not be disassembled; X stands for High Performance, Detachable; q stands for high performance level; y stands for ultra-low voltage, except for power saving, there is no other advantage, it cannot be disassembled; The two letters belong to the combination of the above letters: MQ standard voltage to high-performance processor; HQ high-voltage to high-performance processors; MX standard voltage high-performance processor; QM to high-performance standard voltage processors; XM high-performance standard voltage processor.

You made a typo Frequency lock refers to the lock frequency of the CPU multiplier x external frequency = CPU frequency For example, the external frequency of AMD 640 is 200m, the frequency of the octaber is 15, and the main frequency is equal to As for the good or not locked, the wise will see the wisdom If you like the limit overclocking, you will buy the unlocked If you like the small superclock or not the overclock, you will buy the locked frequency Overclocking is mainly directly related to the CPU fan, motherboard memory, and power supply.

Hello, the first is that the lock frequency is not the screen.

The lock multiplier is also divided into two cases: one is that the highest octave is locked, but it can be adjusted downward; The second is to lock a certain octave, which cannot be adjusted up or down.

The landlord's problem depends on personal use:

The lifespan and performance of the frequency-locked CPU are relatively guaranteed.

The price is more expensive than the one that is not locked in the frequency.

10 points is a bit low.

Think of the CPU as a high-speed porter, and the frequency is the number of passes he can carry back and forth per second.

If the porter does not change (i.e. the amount he carries per trip does not change), then the higher the frequency, the higher the handling efficiency.

The same goes for CPUs. The same CPU model processes the same amount of data per clock cycle (per trip), so the higher the frequency, the more processing power.

The frequency of the CPU has an external frequency and a main frequency. The external frequency is the frequency at which the CPU and other external devices cooperate, and the main frequency is the frequency at which the CPU calculates itself. The main frequency is generally much higher than the external frequency.

There is also an octave:

The frequency doubling of the main frequency is the external frequency, that is, how many times the main frequency is the external frequency.

The term "overclocking" generally refers to increasing the clock speed, which, as mentioned above, increases computing power.

The general CPU is locked and cannot be changed, so that the external frequency must be increased in order to exceed the main frequency, which will lead to increased pressure on external devices and unstable system.

The CPU without locking the frequency multiplier, such as the black core 5000+, can increase the main frequency without changing the external frequency, which is much easier to overclock, and can easily improve CPU performance.

Let's add a few more points, I type so many words......

Refers to the frequency doubling, U main frequency = outer frequency x frequency doubling, in the case of fixed external frequency, the adjustment of the frequency doubling is overclocking, and the upper limit of the frequency doubling adjustment without locking the frequency is not sealed, in the case of the same configuration, of course, the higher the main frequency, the faster the operation and processing speed.

AMD is not locked multiplier, the main frequency of the CPU = the external frequency x the multiplier. The higher the frequency, the faster the computing and processing speed.

Generally, overclocking only adjusts the frequency doubling to improve CPU performance. If the external frequency is increased, the CPU, memory, PCI devices, and hard disks will greatly improve the overclocking performance, but the system will become unstable.

CPU Locking is the process of locking the frequency of a CPU to a specific number and cannot be adjusted. Many of Intel's CPUs are locked, while AMD's are only locked in the later stage. One of the reasons is to prevent retailers from overclocking and inflating their speeds, thus selling them more expensive.

In order to prevent some unscrupulous businessmen from making profits with CPU Remark, CPU manufacturers limit the CPU to work only on a certain frequency, which is called "frequency locking". At present, the CPU frequency lock is still limited to the lock multiplier, and the lock frequency is also divided into two situations: one is to lock the highest frequency multiplier, but it can be adjusted downward; The second is to lock a certain octave, which cannot be adjusted up or down.

Frequency locking is to lock the frequency multiplier of the CPU at the factory to a fixed value, so that its frequency multiplier coefficient can no longer be changed. In the early days, CPUs were basically unlocked, but as the microprocessor production technology became more and more advanced, many high-quality products could be "overclocked" under the condition of increasing their frequency doubling and external frequency, which brought benefits to ordinary users, and also gave some illegal traders an opportunity to flood the market with a large number of remark (polished) CPUs, damaging the interests of consumers. In order to change this mess, manufacturers have to "lock the clock" of their CPUs, which is also a last resort.

Are you talking about mobile phones? Nowadays, smartphones have the function of standby to reduce power consumption, and after the screen is locked, the CPU will generally be at a lower operating frequency, and of course it will automatically resume after unlocking. As for the impact you said, I think it should have no effect, but there may be a freeze at the moment of unlocking.

It's definitely self-adjusting. Smarter. More energy-efficient and cooling.

CPU manufacturers have painstakingly researched the function. It's definitely better than frequency locking.

Frequency locking is generally only available to brand machines, and the machine that does not lock the frequency can make the computer performance to a higher level after overclocking, and the frequency locking is nothing, because the brand machine wants to ensure the normal operation of the machine and the stability of the work, and the frequency locking is just not to let the overclocking go, which is just not able to improve the performance, and will not have an impact.

There is a phase-locked loop circuit inside the CPU.

Through this circuit, the number of multipliers of the CPU can be set.

From a few to 20 times and so on.

Frequency-locked CPU is to limit the phase-locked loop circuit, so that the CPU can only run on a certain frequency octave or the maximum frequency can not be higher than how many octave.

That's locking!

Unlocked means that there is no locked multiplier.

This means that this CPU can be superdoubled.

But not every product is perfect.

The hardware of the CPU still has a limit, and it is impossible to overclock it too much.

That is, on the basis of the current frequency, it is just a matter of increasing the frequency by some more.

If the motherboard supports it, it can be super, but if it is super broken, you will be responsible for it.

The CPU frequency is the frequency multiplied by the external frequency, and if the frequency is not locked, it is not locked to the frequency multiplier, so it is easy to overclock, just turn up the frequency. You can overclock with a motherboard that supports overclocking. It's certainly not infinitely overclocked either. It is also not possible to start if it is super high. Instability.
