When you buy a laptop, based on its cost, you expect good performance. And still it's not enough. But you can increase the processing speed of the central processing unit (CPU) from that declared by the manufacturer. Therefore, the question arises: how to overclock the processor on a laptop in order to get more efficient work for the same money. There are several options available and safe, which we'll cover in this article.

Let's start with the question "why"

It seems that the laptop is only 3 years old and it has never failed when performing any tasks (play a new shooter, watch the latest video rentals, transcode videos).

But now it can not cope with half the needs. What will you have to do - change your laptop? But you can try to "revive" your electronic friend by overclocking the processor. Performance will increase slightly. If you do everything right, the results will please. In addition to increasing the clock frequency, memory starts to work faster, and as a result, the speed of applications increases slightly.

But overclocking a laptop processor is half the battle. You have to pay for everything in this life:

• Performance will increase, but power consumption will also increase at the same time. This means that battery life will inevitably decrease.
• In addition, now the laptop will heat up much more. You will have to think about the cooling system or, at least, do not block the special slots from the bottom and side.
• CPU life is likely to decrease.

Windows also improves performance

Overclocking the processor in a laptop is a bit difficult, but possible. Manufacturers mobile devices, of course, thought about protection and took care in advance to ensure the best performance at maximum frequency, when you need to speed up the work. When the processor is idle, the frequency automatically drops. But you can improve performance without harming the laptop using system tools by changing the power mode.

For this, in the operating room Windows system there is software tool - « Power supply". You can find it by going to Control Panel. The figure below shows the window that will appear in Windows 7 or 8.1.

You need to go to the section Power supply» and select « High performance».

This is how you can "overclock" the laptop processor without the risk of breaking something. The performance gain will be immediately noticeable.

Overclocking via BIOS

In some models, it is possible to overclock the laptop processor with standard tools from the BIOS. To get into this system, you need to turn on the laptop and press a certain key on the keyboard. A hint of which button to press will be visible for several seconds on the monitor screen. For example, on the screen of the hp monitor, the inscription shown in the figure below will appear.

After this condition is met, the initial menu will appear, which will indicate the key that you need to press to get into the BIOS.

Consider the sequence of actions that must be performed to overclock the processor:

Be warned that most often manufacturers block the CPU to prevent the user from changing the clock speed on their own.

Overclocking with dedicated apps

For relatively old laptops, it is possible to overclock the processor using a small program paired with the program Prime95.

Further implementation of any overclocking method is associated with the risk of damaging the laptop. All actions must be performed with extreme caution, in small steps.

You need to understand that the maximum possible to achieve a slight increase in the frequency of the processor - within 10-15%. A further increase is possible if the cooling system is prepared and the power supply of the chip is changed. Since during acceleration, along with an increase in frequency, heat generation also increases. By the way, modern processors have a two-level overheating protection system. If the temperature threshold is exceeded, the processor automatically forcibly lowers the frequency and voltage, which leads to a decrease in heat generation. If the temperature does not fall below 95–110º, the laptop either turns off or freezes.

CPU-Z program

Before overclocking, you need data about the chip installed in the laptop. This utility will help CPU-Z. This information is required for the program.

SetFSB utility

Deliberately designed for fast and easy CPU overclocking. With its support, you can safely change the frequency of the system bus without rebooting operating system, bypassing the BIOS.

The program has an interface that is quite understandable for work, and the entire overclocking process takes place by step-by-step movement of just ONE slider.

If this laptop is supported by the program, the chip frequency data will be visible in the lower right corner.

The sequence of actions is extremely simple: increase the bus clock frequency in small steps and test it with the program Prime95.

Prime95

A small utility that can measure the performance of a computer. The measurement process is based on performing calculations of Mersenne primes. This action uses all the capabilities of the laptop.

Optionally, you can check both the RAM and the processor itself. While the program is running, you must be prepared for the fact that the computer will noticeably slow down.

The frequency increase is made in small steps until a freeze occurs. After the performance has been saved, Prime95 testing must be terminated and exited from the CPU setup program.

Conclusion

If everything went well, you can stop there. But this is not the whole complex of works. Performance depends not only on the frequency of the processor, but also on the frequency of the memory. It can also be increased by selecting the necessary timings. Tips from friends and Internet searches will help you set up your laptop. Overclocking without prior preparation can be harmful. For game lovers, the next step is overclocking the graphics card. The main thing is that all actions are thoroughly thought out, and then the efforts will not be in vain.

The Core microprocessor is designed to create high-performance mobile computer systems.i5-3210M. Characteristicsof this chip are still relevant and allow you to run most of the existing program code. It is this CPU model that the short review brought to your attention will be devoted to.

Positioning

Microprocessor was released in 2012i5-3210M. Characteristicsat that time he really had advanced and allowed him to perform any programming code, including the most resource-intensive. Although quite a lot of time has passed since then by the standards of computer technology, the hardware part of this solution is still relevant. In any case, the chip in question is intended for use in high-performance laptops with long battery life.

CPU parameters

The generation of CPU codenamed Ivi Bridge belongs toi5-3210M. Characteristicsindicate the presence of 2 physical cores, which, due to the use of NT's proprietary technology, can already process the code into 4 data streams at the software level. The crystal of this processor had a size of 37.5 mm x 37.5 mm and was manufactured according to the 22nm technology. At the same time, semiconductor elements had a three-dimensional TriGate layout. The base clock frequency is 2.5 GHz, but due to the support of automatic TV overclocking technology, its value can be increased up to 3.1 GHz. The thermal package of the microprocessor is limited to only 35 W, and its maximum temperature is 105 ° C. The chip in question is installed in the FCPGA988 socket, which is used only in laptops.

Memory subsystem characteristics

Equipped with an integrated RAM controllerIntel i5-3210M. Characteristicsits said that it can work in dual channel mode. That is, the use of an increased number of memory modules, but with a smaller volume, instead of one large bar, allows you to increase the performance of your mobile PC by 10-15%. For example, it is better to install 2 modules of 4 GB than one of 8 GB. Three types of RAM chips can be used in conjunction with this processor: Their clock speeds can be 1333 or 1600 MHz. You can also install a faster RAM, but this will not give any increase in performance. The frequency of their operation will automatically drop to the maximum possible 1600 MHz. The largest amount of RAM that the controller in question can address is limited to 32 GB. Real laptop models based on such a CPU were equipped with either 4 or 8 GB. The cache memory in this microprocessor has a three-level organization. Its first level is 128 kb and the second level is 512 kb. The largest size is the third level of fast memory, which is 3 MB.

Integrated graphics

The integrated graphics core is equipped with the i5-3210M processor. The characteristics of the latter indicate the initial level of performance. Its model is HD Graphics version 4000. This video card is integrated on the same substrate as the processor part. That is, the production technology of this graphics accelerator complies with the tolerance standards of 22 nm. Its clock frequency in the basic mode is 650 MHz, but due to automatic overclocking, the latter value can be increased to 1100 MHz. No more than 3 monitors can be connected to this accelerator at the same time. In order to improve performance, this accelerator can directly interact with the third cache level, which is 3 MB. Part of the RAM of the computer system acts as a video buffer.

Relevance of the chip today

As noted earlier, the i5-3210M is still an actual microprocessor device. In the 3DMark06 test, this chip scores 3553 points, and by this value it bypasses the representatives of the previous generations i5-2520M and i7-840QM. The first of them scores 3542 points, and the second - 3532. But at the same time, it is inferior to the FX-7600P from AMD, which scores 3589 points. If the laptop is equipped with a discrete graphics card, then the PC turns into a full-fledged gaming system. Of course, not all toys in this case will go with maximum parameters, but most of them will definitely run.
