AMD X4 635 multiplier reduced

Enter the BIOS and set C&Q,, some called cool and quiet to disenable

Multiplier settings. The x4 635 octave is.

Not 13

Install AMD's PowerNow software to turn off Win7 and turn it on to the highest in the System Security power options.

Enter the BIOS to turn off the "cold and quiet" function

The X4 641 CPU is not suitable for overclocking!

The main reason is that this CPU is obtained by AMD's APU 3850 shielded display core. His structure is complex, and the frequency of the core part of the display is also linked to the frequency of the CPU itself! Although the display core is shielded, the actual display core part is still working (as can be seen from the TDP), because the structure is too complex, so there is a problem that affects the whole body!

All frequencies inside the CPU are hooked, so once you adjust the external frequency, other frequencies will follow, and overclocking is very difficult.

However, it does not mean that it cannot be exceeded at all, and the amplitude is still there. The specific way to overclock is to increase the CPU external frequency in the CPU settings in the BIOS, and at the same time reduce the multiple of the HT bus, and lock the PCI-E frequency to 100. The specific operation method of each motherboard is different, you have to read this manual.

Overclocking is also a technology that takes into account many related factors, because the frequency of the CPU affects the PCI-E frequency, the memory frequency, the bus frequency, ...... at the same timeIt's not a sentence or two that can be made clear.,Generally, you can't adjust the amplitude too much, at most5MHz a jump of slow adjustment.,How much can be exceeded.,How much it can be exceeded depends on the CPU system.,Can't generalize.。

In fact, if you plan to overclock, why not buy 651k!? The proof with the k flag does not lock the multiplier, so that the overclocking will directly increase the multiplier and it will become very simple without adjusting anything else.

The 641 can't be overclocked, and it's not interesting to overclock, so don't think about overclocking.

Can be overclocked to.

AMD Athlon II X4 635 This CPU is not to be overclocked for the average gamer. You wouldn't normally use half of it. Overclocking is generally not very stable. Unless you are a computer enthusiast + computer expert.

If you can overclock, the main frequency, the voltage of the core is added, and it is no problem to overclock.

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.

After the core is turned on, the voltage of the C2 core is generally increased to stabilize at C3, and it is estimated that it can be up to 4G, depending on whether you will exceed it.

It's good, it's definitely enough.

At this time, the external frequency has reached 260

If it rises again, it may need to be declocked and pressurized.

Overclockers don't have the highest thing, only higher, just enough for themselves、、、

As long as the temperature is not high, the higher the frequency, the better.

Can be overclocked but not turned on.

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!!

Hello, overclocking is divided into the following steps:

Replace the heat sink: This step depends on whether the original CPU fan and heat sink are excellent, and the high-quality fan** is generally more than 50 yuan, and this investment should be guaranteed as much as possible. Very useful for overclocking.

While replacing a high-quality fan, pay attention to applying thermal grease to the contact part between the CPU and the base of the fan heatsink, which can increase the heat dissipation speed.

Increase CPU multiplier: This method is currently only suitable for K62 and Duron and T Bird's CPU, if it is Duron and T Bird, you also need to use a pencil to crack the frequency doubling, many articles have introduced, and I will not repeat it here. Over-frequency multiplier requires the motherboard to support modifying the frequency multiplier, so you should pay great attention to it when purchasing a motherboard.

For PIII processors, the current general frequency is 100 external frequency, only more than 133, and when the heat dissipation is excellent and the voltage can be added, it can even reach more than 150. But at this time, your computer's memory and graphics card are required to work at such high frequencies.

Therefore, relatively speaking, a PIII processor with 100 external frequency is an ideal CPU for super external frequency. This method works best when used in conjunction with the method of increasing the CPU frequency multiplier. Of course, this requires your motherboard to support the adjustment of the external frequency, and some motherboards support mega adjustment, which is specially designed for super-external frequency.

Increase voltage: Increasing the voltage has a certain danger, it is recommended not to use, if you really need to increase the voltage to increase the stability after overclocking, you should add it little by little, and monitor the temperature to be safe. For Intel's CPU, the effect of adding a little voltage is obvious; For AMD's CPU, you can add some more voltage.

It is worth mentioning here that the motherboard should support changing the voltage, otherwise there will not be much room for overclocking. If you need an adapter card, it is best to choose or replace an adapter card that can adjust the voltage.

This host is congenitally insufficient, and it is basically a luxury to want to run a large-scale ambulatory orange show.

First of all, the A55 motherboard is paired with the Athlon II X4 641, which is a dual-module four-thick core CPU inherited from the bulldozer architecture, and the performance itself is weak, and there is no way to upgrade to a stronger CPU, which is restricted. It's a bit hard to use it for large-scale games, but it's okay for ordinary online games.

Secondly, the memory is only 4GB is also stretched, and if you want to run a large game well, 8GB of RAM is the passing line, and 12GB or even 16GB will not be bottlenecked.

Finally, the GT520 is the lowest-performance entry-level graphics card, commonly known as the "bright card", which means that it can be used to light up the computer, and it cannot be extravagant for performance.

If you want to improve your gaming performance, you need to add at least 4GB of RAM, and at the same time, get rid of the original junk GT520 graphics card and replace it with a GTX750Ti or higher discrete graphics card. Of course, after changing the graphics card, you should pay attention to whether the rated power of the original host power supply is sufficient, if the rated power is lower than 350W 400W, it must be replaced.
