How to overclock AMD X240 CPU

Overclocking can be done via BIOS:

Turn on the computer, enter the BIOS, in the CPU options, there will generally be a position that supports overclocking, which is a set of numbers, for example, the default external frequency of the CPU is 200MHz, then 200 will be displayed in this position, and you can choose to change this external frequency at this position. If the external frequency is increased, the frequency of the CPU will increase, and the purpose of overclocking will be achieved.

It should be noted that when overclocking the external frequency, it should be exceeded little by little, for the first time, you can first adjust it to 205 external frequency, and then restart it to see if the system is normal, if it is normal, and then come back, adjust to 210, if it is normal and then adjust, so adjust the external frequency again and again, until the system can not start normally when adjusting to a certain number, then add voltage to it, and add it little by little, otherwise it may burn out. The first voltage to be added, restart to see if it can be restarted normally, if it can't be restarted, it is the overclocking limit.

CPU heat dissipation is also very important, if the heat dissipation is not good, not only is it super low, but it may also burn out the CPU. So be sure to have a fan with good effect, and if necessary, you can cool it with water to dissipate heat.

After the CPU exceeds the external frequency, the frequency of the memory will of course also follow. Therefore, many times overclocking is unsuccessful.

Often it's not the CPU physique problem, but the memory problem. When overclocking, as long as the PCI-E is locked at 100, then the graphics card will not follow. If the PCI-E does not lock up when overclocking the CPU, it will cause the graphics card to burn out.

How much memory can be exceeded depends on the physique. A good physique can exceed 1500, and if the memory is a dual-channel double bar (not a suit), it is difficult to overclock. Unless it's a suit, or it's better to use a single channel of memory.

The landlord sees it for himself, although it is not very clear, but it can be used.

Here's how to overclock your AMD Athlon™ II X4 640 CPU:

3. Find the Clock voltage in the "Performance Control" menu on the left, and click with the mouse.

3. After entering the page, modulate the parameters as shown in the following figure:

4. Set the parameters of HT, and pay attention to whether the values of other parameters change;

5. After the adjustment is completed, go back to the beginning, check the CUP status, and then click OK to complete.

AMD Athlonon II X4 640 is a quad-core processor, the main frequency is 3GHz, the thermal design power consumption is 95W, the core voltage is, this processor is locked and doubled, overclocking can only exceed the external frequency, the overclocking method of this processor is in the case of constant voltage, the following is the specific operation method:

First, boot into the MB Lntellignt Tweaker in the BIOS, and overclocking items are all in this option. Athlon II X4 640 This processor is not a black box, so the first frequency doubling does not need to be set, we directly set the third CPU host clock control, that is, the CPU external frequency, here you can enter the external frequency you want, the amplitude is 200 500, I directly choose 250. It is recommended not to operate the other options, and the voltage default is fine.

Save the reboot. If it can be restarted, the computer is running relatively stable, indicating that the overclocking is successful, if it cannot be started, it means that the external frequency setting is relatively high, and it needs to be pressurized.

Second, the following parts of the red letter are to regulate the voltage, in order of memory voltage, northbridge voltage, PCI voltage, NB vid, CPU voltage adjustment, and CPU vid. Here you just need to adjust the CPU voltage, i.e. CPU Voltage Contiol, and save the voltage added on the default voltage to give it a try.

In summary, the AMD Athlon II X4 640 has good overclocking performance, and the overclocking performance is even better with the core turned on. The current processor has already been surpassed (after the core is turned on), and the performance has been greatly improved. As shown in the figure, the overclocking pulls the external frequency to 255MHz, adjusts the voltage to, the frequency is reached, and the performance is improved by 30%.

If you overclock, it's no problem, you can go into the motherboard BIOS to modify the parameters, in the frequency voltage control column, directly adjust the external frequency, the original is 200, it is recommended to start adjusting to 220, and then slowly adjust up, the voltage does not need to move, it is not recommended to pressurize and overclock, it is very dangerous!!

Overclocking of a computer is to increase the working frequency of hardware such as CPU, graphics card, and memory through the overclocking method of the computer operator, so that they can work stably at a frequency higher than their rated rate, so as to improve the working speed of the computer. The English name of overclocking is "over clock", which is a technical means to obtain performance beyond the rated frequency by adjusting the hardware settings to increase the main frequency of the chip. Take the AMD Phenom II X4 955 black box CPU as an example, its rated operating frequency is Hertz), as a native quad-core processor, it can steadily exceed the 4GHz air-cooled limit frequency through software alone, and the system can run stably, completing a successful overclocking.

Take, for example, the most effective CPUs for overclocking. The production of CPU can be said to be very sophisticated, so that manufacturers can not control what frequency each CPU can work at, manufacturers have actually done many tests themselves, and the CPU that can work at high frequencies is marked as high frequency, and then it can be sold at a higher price. But in order to ensure its quality, these marks have a certain amount of surplus, that is, a CPU working at 2500MHz is likely to work stably at 3500MHz, and in order to explore these potential surpluses, it can be overclocked.

, controlled in the Turbo Core in the Clock voltage list.

This motherboard is mediocre in all aspects, and overclocking is not recommended, otherwise it may cause damage to the components, and the gains outweigh the losses.

I advise you not to overclock!

And you're pretty average with this board.

Overclocking has high requirements for CPU motherboards and power supplies!

And you need your CPU to be overclocked and your memory is good enough!

And let's be honest.

Even if you overdo it, the performance boost of this CPU is very low.

Not much different from the default one.

It also increases the instability of the system.

It is recommended not to exceed!

CPU 240 device, there is no need to overclock, it has no effect.
