What happens if you overclock the processor on a laptop. Extreme laptop overclocking
It happens that the hardware resources on a low-power computer are not enough to ensure smooth operation of graphically complex games or programs like Adobe Photoshop. The power of the device is largely influenced by such an indicator as the processor clock speed. If desired, you can increase it a little by doing some manipulations. You will learn about these manipulations and how to increase the processor on a laptop (that is, its clock frequency) in this article.
General information about computer processor frequency
Before you start following the instructions, it is advisable to at least have a little understanding of the theoretical issues about processors and their clock speeds.
In short, the processor frequency is a value that shows the number of simultaneous operations performed by the processor per unit of time. Most modern processor microchips have a nominal frequency of 1 to 4 GHz. It is a mistake to believe that if you “overclock” the processor, that is, increase its frequency, the number of simultaneously performed actions will increase. No, the number of tasks will be the same as before overclocking, but the computer will cope with them noticeably faster than before. The number of operations performed is influenced by the number of processor cores (most modern laptops are quad-core), and the frequency is responsible for performance (information processing speed).
How to increase the processor frequency on a laptop - consequences
Here are some other key points to consider:
- Increased energy consumption. The higher the frequency, the more energy the computer needs to perform the same operations. If you have a desktop PC, this indicator is not particularly important, but for laptops, autonomy is one of the main characteristics.
- Increased heat generation. The compactness of laptops is not only an advantage, but also a disadvantage: all parts, unlike the system unit of a desktop PC, are located close to each other, and the cooling system is also not particularly reliable. Therefore, it is advisable to avoid prolonged overheating or use special cooler stands for laptops.
- Not warranty cases. If the user performs any manipulations with the processor incorrectly, which will lead to critical overheating of the computer components, this situation is not considered a warranty. That is, you will pay for repairs out of your own pocket.
- Before overclocking the processor frequency, think about the consequences of the work, especially if you are not a professional in computer matters. All actions are performed at your own peril and risk, so strictly follow the instructions.
Change your power plan
This is the safest way to increase productivity using system tools. Change your power plan to provide more power to your PC's components while improving the performance of your entire device. Do the following:
Of course, in this way you will not overclock the processor frequency several times. However, this method allows you not to lose the factory warranty, and is absolutely safe for computer components and the operating system as a whole.
Changes in BIOS settings
Another way to increase processor performance on a laptop is to change the parameters in the BIOS routine. Go to the BIOS menu when you start the device again (F1-F12, Delete or Escape keys on different laptop models, depending on the manufacturer). You can find the right key using the “poke method” or find information on your model on the Internet. After you enter the BIOS, look in the sections for the item “CPU Frequensy” or “CPU Lock” (also depends on the manufacturer) and set the computer system bus frequency to the value you need. Confirm your actions, exit the menu and restart the device.
Check whether the processor temperature has increased significantly as a result of the manipulations you have performed. Download and install one of the programs designed for this (for example, Aida 64). Without opening other programs, check the temperature at minimum load. If it rises above 50 degrees Celsius, it is imperative to reduce the set processor frequency.
How to increase processor performance on a laptop: an easy way
If you do not want to understand the BIOS interface, install a program that can slightly increase the maximum frequency. They automatically perform the necessary actions for you. You need to choose software depending on the processor manufacturer:
- AI Booster or AMD Overdrive (for laptops on the AMD platform);
- Intel Desktop Control Center (for laptops on the Intel platform).
- Read the instructions carefully before operating the programs.
There are different methods for overclocking a computer processor, but each of them is quite a serious risk. You can simply burn out the processor if something goes wrong. Therefore, it is best to decide before purchasing a laptop what exactly you need it for and select a computer with sufficient power.
part one: hardware changes in processor and memory parameters
Warning: The modifications described in this article may result in irreversible damage to the laptop and further expensive repairs! Any modifications described in this material are made by users at their own risk.
If you are not sure of your actions or are not very familiar with the devices described in the article, you should not resort to the overclocking methods described!
Introduction
Overclocking a laptop is a little more difficult than a desktop computer. If in overclocking a desktop computer 80% of the time is spent on selecting the necessary parameters in the BIOS, then in overclocking a laptop this part of the time will be spent searching for the answer to the question “How can I overclock it?”, because the laptop’s BIOS does not offer overclocking settings.
In a laptop, just like in a desktop computer, you can overclock the processor, RAM and video card.
Video card
There are usually no problems with it, there are many programs that allow you to easily overclock it, for example, RivaTuner, AtiTool and others. It is also possible to overclock a video card in hardware (modify its BIOS, make a volt mod of the video chip and video memory), but this is not easy and dangerous. Hardware overclocking of the video card does not affect the loading speed of the OS, so the only convenience is that after reinstalling the operating system you will not have to re-create overclocking profiles. In addition, this method is much more dangerous than software, because if, for example, the video BIOS modification is unsuccessful, you will not be able to install another video card in a laptop, and blindly flashing a working BIOS version is not always possible.
RAM
In AMD chipsets, the memory frequency does not depend on the FSB frequency, but successful independent overclocking is only possible when using an AMD processor. In the case of pairing an Intel processor with an AMD chipset, the maximum possible memory frequency is selected according to data from the SPD (from those supported by the chipset, of course), i.e. in fact, to overclock the memory in this case, it is enough to flash a higher frequency into the SPD.
CPU
You often have to work hard with it to get the desired result. There are three main ways to overclock the processor in a laptop:
1. Software overclocking. It is carried out using programs that control the clock generator (TG, PLL chip, clocker, clocker) and can change the FSB frequency on the fly. There is one “but” here - for the program to work, you need to know what clock generator is installed in your laptop, and for this you will either have to disassemble it and look for the treasured microcircuit on the board, or select it by trying each of the considerable list of TGs. Examples of overclocking programs are SetFSB, Clockgen and others. There are also some factors limiting the use of this overclocking method, namely:
- not all PLLs support software control;
- It happens that overclocking is blocked by hardware or at the BIOS level. Those. even if the required TG is supported by the program, overclocking will not be possible;
- new laptops with new TGs are released almost every week, so adding support for these TGs sometimes takes considerable time;
- The memory frequency increases along with the FSB frequency, so when overclocking you can run into memory.
2. BSEL-mod. The method is to apply low (logical 0) and high (logical 1) levels to the BSEL pins of the processor. By low and high level we mean a voltage of a certain value; it can be different for different processors. It is physically implemented by shorting to ground and isolating (or shorting to the Vcc pin of the processor) the corresponding pins of the processor. The main advantage of this method is that the chipset sets a new FSB: DRAM ratio or higher timings for RAM, so overclocking will not run into memory, but not always. As with software overclocking, the BSEL mod has its pitfalls:
- The latest Intel mobile chipsets (tested on 945PM, PM965, PM45) after the BSEL mod block the processor multiplier at x6, and the resulting frequency is lower than the original one. There is no such problem on AMD chipsets (tested on an Xpress 1250 chipset with an Intel T2330 processor, BSEL mod 133->200 was successful);
- The FSB frequency in this way can only be switched to standard values such as 133, 166, 200, 266, etc.;
- If the chipset does not officially support the FSB frequency at which the BSEL mod is planned, then overclocking will most likely fail. This can happen for various reasons, for example, blocking or lack of support for other BSEL combinations in the BIOS, or the inability of the chipset to operate at a new higher frequency, etc.
3. Clock generator mod. Direct intervention in the electrical circuit connecting the TG with the processor and chipset. The method is similar to the BSEL mod, only it is carried out with the BSEL pins of the TG chip, not the processor. In this case, in some cases it is necessary to disconnect the BSEL pins of the processor from the modified BSEL pins of the TG. Advantages of this method:
- it is universal and fits almost all laptops;
- Unlike the BSEL mod, the BIOS chipset does not need to have official support for the required frequency, and such overclocking cannot be blocked in the BIOS. In general, the chipset does not know at all that the new FSB frequency differs from the frequency specified by the BSEL pins of the processor.
Flaws:
- quite difficult to implement, requires skills in handling a soldering iron and some theoretical knowledge, as well as the presence of a multimeter and some other technical devices;
- as in the case of the BSEL mod, the frequency can only be switched to standard values such as 133, 166, 200, 266, etc.;
- The memory frequency increases along with the FSB frequency, so overclocking may come down to memory.
- With this method, the chipset does not switch its internal timings, and it is unlikely that it will be possible to increase the FSB frequency by more than 66 MHz.
The last 2 methods are hardware, i.e. they start working immediately after pressing the “ON” button; after reinstalling the OS, you also do not need to configure everything again.
Overclocking a video card
The Samsung R560 has a GeForce 9600M GS/GT discrete video card with 256/512 MB GDDR3 memory soldered onto the motherboard. I have the GS version with 256 MB. It was overclocked using the nVidia system tools program. There is no point in describing this process in detail, because... it consists of moving sliders in the program. I will only say that after setting the frequencies, it is necessary to test the system for artifacts and heating with “hairy” tests such as FurMark or a cube in AtiTool. Artifacts are image distortions during overclocking. Here is the maximum, stable overclock of my copy:
I set the frequencies to autoload using rules in the same nVidia system tools. It is worth noting that when idle, the card itself resets frequencies to save energy.
Overclocking the processor and memory
A little background
Here everything turned out to be not as smooth as with the video card. When I still had a Samsung R70, I wanted to overclock it in software because I had no idea about other methods. For this purpose, I disassembled the laptop, found the TG and went to download programs to change the FSB frequency. The laptop was relatively new at that time, and there was no support for the TG I needed in any program. More precisely, they had TG models similar to mine, they even allowed you to change the frequency, but after a few seconds the laptop would freeze.
I was not too lazy and wrote a letter to Abo, the developer of SetFSB, asking him to add support for my TG. However, he replied that the specified TG does not support software frequency change. Then I wrote to him about the situation regarding changing the frequency when choosing another PLL, but in his response he wrote that he did not understand how this could be implemented.
But I didn't stop there. After digging through dozens of pages in search engines and websites in Chinese, I found and downloaded a technical description (datasheet) for my TG and its immediate family. From there I learned that the TG is controlled by writing data to its registers. And the best thing is that the contents of these registers can be viewed and changed in SetFSB. Having carefully studied the datasheet, I finally found a register with which I could control the frequency of this ill-fated PLL:
It can be seen that the 7th bit is responsible for turning on/off the manual control mode, and the 4th to 2nd bits are responsible for setting the frequency. True, with its help the frequency could only be changed in steps from one standard frequency to another, i.e. 166,200,266, etc. - just like the BSEL mod does. And this, too, seemed to be a dead end, because the R70 had a processor with a frequency of FSB=200 MHz and a PM965 chipset, which does not officially support a higher frequency. Those. When switching from 200 MHz to 266 MHz, the laptop froze. I didn’t yet know how to make a chipset voltmod, however, even if I could, it’s unknown whether it would have helped or not. But fortunately, a friend had a T5750 processor that ran on a 166 MHz FSB, and we swapped. Overclocking was successful with this processor; by changing the register value, I moved the frequency from 166 to 200 MHz and got an increase in the processor frequency by 400 MHz and the memory frequency by 133 MHz, i.e. the processor began to operate at 2.4 GHz, and the DDR2 memory - at 800. Although, to be honest, the absolute gain from overclocking in this case is somewhat doubtful, since my T7300 has a second level cache of 4 MB, and the T5750 has half as much . And it is not clear what is better in this case - an extra 2 MB of cache or a 400 MHz frequency increase.
And everything seemed to work out, only the frequency was set every other time, and in other cases the laptop froze, and it froze more often than the frequency was set. But what an achievement. I wrote about this register to Abo, and he subsequently added support for my PLL to SetFSB. True, the support is not the same as for “normal” TGs, but at least there is some scope for action. By “normal” TGs I mean TGs that allow you to change the frequency in steps of ~1 MHz, and not according to the table.
The R560 has exactly the same clock generator. By the way, not all copies of the R70, R560 and R710 (analogous to the R560 with a 17-inch screen) have the Silego SLG8SP513V TG. In some, TGs from IDT and SpectraLinear were installed. The situation with their support is just as bleak as with SLG, and in the SpectraLinear TG you cannot switch the frequency at all. Here is the TG itself from Silego:
Overclocking process
The R560 has an Intel PM45 chipset that officially supports 266 MHz and can even run at 333 MHz, which would seem to create ideal conditions for overclocking my T7300 (200*10). However, this was not the case. When the laptop starts, the chipset, depending on the FSB frequency (more precisely, not on the frequency itself, but on the BSEL combination of processor pins), sets timings for the memory, which it takes from the SPD. And this is the situation: for FSB 200 MHz the timings were set to 6-6-6-15, and for overclocking on FSB 266 MHz the timings were 7-7-7-20, according to SPD. There were several ways out:
- make a BSEL mod at 333 MHz, then the multiplier will be locked at x6 and the resulting processor frequency will remain the same (333*6=2.0 GHz), which is quite good, considering the wider processor bus and the fact that the memory frequency would be at this case 1333 MHz. The timings must be set correctly;
- modify the SPD of the memory modules so that the chipset sets timings of 7-7-7-20 at a FSB frequency of 200 MHz. At the same time, it would be possible to continue with software overclocking, because the memory would function in standard mode.
The first option, which I had so hoped for, disappeared after its practical testing. In this position of the jumpers/insulators on the BSEL pins of the processor, the laptop did not start at all. This situation is possible for a number of reasons, but only Samsung engineers can know for sure.
The second option was relatively simple to implement. There is special software for flashing SPD, I used Taiphoon Burner 6.1. However, a problem arose during the firmware: due to the fact that the R560 uses DDR3 memory, different programs for some reason produce different information about the SPD, but this ultimately did not interfere with my work with the SPD. After some experiments and flashing the SPD back and forth, it turned out that the laptop stubbornly does not want to start if Cas Latency is not equal to 6 for the FSB frequency of 200 MHz, but I needed CL = 7. The rest of the timings without CL=7 were set perfectly. For some time I searched on various forums for the reasons for this situation, but to no avail. Therefore, it was decided to test the timings 6 -7-7-20. Contrary to my expectations, the system not only started, but also worked stably even in stress tests.
This is what is written in the SPD by default:
Here's a modified version:
This is what the timing editor looks like:
It is worth noting that if you only have one memory stick, then you should not bother with flashing the SPD. Because if the timings are set incorrectly, the laptop will not start with this bar. Especially for experiments, I bought another cheapest gigabyte memory stick, which I don’t mind losing too much. If the laptop has two flashes and one of them is not flashed correctly, then you can insert a working one, boot the system on it, and then “hot” plug in the non-working one and flash it back to the working timings. There is a risk of burning the bar or, even worse, the motherboard, but if you don’t have a programmer at hand, there are no other options. By the way, I brought the bar back to life in this way about 10 times and now it functions wonderfully. Later it was found out that there is a safe way to seal the contacts on the strips with tape. Its essence is that you need to cover with tape all the contacts on the memory stick, except those that are needed to read and write the SPD chip. For So-DIMM DDR3 204pin, you need to leave the last 5 contacts on both sides of the strip uncovered. If the memory is different, then you need to find a datasheet for the required form factor, and in accordance with it, leave the plus, ground and pins related to working with the SPD chip unsealed.
It would seem that the goal has been achieved, but software overclocking of the R560 has significant drawbacks - not only, as in the R70, when switching frequencies, the laptop freezes with ~70% probability, but if the frequency is successfully switched, it also reboots. It is clear that constant use of this scheme is out of the question; at best there will be a double start, at worst the system will freeze altogether.
Finish line
Fortunately, this was not the end. On the forum, in a thread about overclocking laptops, I came across an entry about how one person (I express my gratitude to Konstantin from Baikonur, without him what I will describe below would not have worked) using a soldering iron and certain skills made a mod, with in which the chipset continued to think that it was operating at a standard frequency, while the TG produced a different one (overclocking method No. 3). The multiplier, of course, was not blocked. After consulting with him, we came to the conclusion that a similar mod could be made for me.
As I said earlier, there are three pins in the clock generator that perform the same function as the BSEL pins in the processor. In the picture these are pins numbered 5, 17, 64.
In most cases, these pins also have additional functions, so you have to think about soldering something somewhere, making a break somewhere, adding additional resistance. In general, this is a rather labor-intensive process that requires special knowledge, skills, tools and parts. To make such a mod, you need to track what the required clock generator pin is connected to on the board. In my case, this was unrealistic, since the track coming out of the TG went into the inner layers of the board after 5 mm. Fortunately, I was lucky, on the pin I needed, namely No. 64, there was a function that does not affect anything during normal operation of the laptop.
According to this table, in order to switch the frequency from 200 to 266 MHz, I needed to unsolder the FS_B pin (No. 64) and apply a low level to it, i.e. short it to ground to get a logical 0. In principle, if you do not short it to ground, but simply unsolder it, then, in theory, nothing should change, since at the standard frequency this leg has the value of a logical one. Without hesitation, I disassembled the laptop and interrupted the path extending from the 64th pin.
I decided to check the laptop and make sure it was still working. Windows booted, and then in the tray, next to the RMClock icon, I saw the number 2.66 on the processor frequency indicator, and I thought it was some kind of glitch. I turned it off and on, but RMClock still showed the same numbers, and CPU-Z showed that the FSB frequency was 266 MHz. The only thing that bothered me a little was the question of why a pin hanging in the air is taken as logical 0. I tested the system for stability for several minutes and finally assembled the laptop with all the screws, and not with three screws “just to hold it.” We can consider that the goal has been achieved.
Here they are, the treasured numbers:
An interesting feature was soon discovered - after the laptop went into S3 sleep mode and exited it, the frequency was reset to the factory one. Then I remembered about the pin hanging in the air, and decided to solder it to the ground, as it should be. After that the bug no longer appeared.
Cooling and testing
At the time when I still had the R70, the issue of cooling was very acute, because the 8600M GT video card installed in it got very hot, and during overclocking the temperature generally reached 100 degrees. Something had to be done about this. During disassembly, I noticed that other laptops have vents right under the cooling fan through which it sucks in cold air. In the R70, as well as in the R560, there are no such holes opposite the fan and, as a result, the air flow weakens and arrives at the fan already heated due to the heat of the motherboard components. I decided to correct this annoying moment in a collective farm, but effective way:
I don’t remember how much the temperature dropped after that, but I can say that this move is approximately equivalent to buying a cooling pad; it reduces the temperature by 5 degrees or more, depending on the load. Speaking of the stand, I recommend everyone to buy one if you want to overclock a laptop. The main thing when choosing a stand for the R560 is the distance between the bottom and the stand - the larger it is, the better. The location of the fans only matters if you drill holes opposite the fan, as I did. It is better if the laptop fan intake vents are directly above the stand fans.
Now about the test results. There’s really nothing to talk about here, the numbers speak for themselves:
3Dmark 2006 (default, 1280×800, overclocked video card, processor and memory not overclocked, XP).
Everest without overclocking:
Everest overclocked:
Regarding the temperature regime, I can say that my T7300 itself is hot; it does not pass S&M or LinX stress testing without additional cooling, even at the factory frequency. Without overclocking, this problem can be solved with a bang by lowering the voltage - the processor can operate stably at a voltage of 0.9875V. But with overclocking there is no place to lower the voltage. With overclocking in resource-intensive games, the processor temperature remains at 80–90 degrees, the video card - about 80. Although, in principle, this level is within normal limits. It is noteworthy that after overclocking, the processor temperature remained virtually unchanged.
Conclusion
Overclocking laptops is not an easy task, but it is interesting and also profitable. Why buy a laptop for 50–70 thousand rubles, when the same (if not greater) performance with the right approach can be achieved from a laptop for 30–40 thousand. The example of the Samsung R560 confirms this. My personal opinion is that the Samsung R560 is simply designed for overclocking. On a 45-nm processor (which, by the way, it comes with), you can achieve impressive results: the processor can be overclocked to ~2.8–3.4 GHz, DDR3 memory - up to 1333 MHz. Not bad for a laptop for ~35 thousand rubles.
Glossary
- The word “voltmod” is taken from English (voltmodification) and means “voltage modification”. Voltmod includes any upgrade of the memory or core supply voltage (not to be confused with changing the motherboard BIOS settings). Voltmod is mainly used to upgrade the power supply system of video cards or motherboards.
- Chipset - a set of chips on the motherboard.
- Timings - delays in accessing data in DDR memory.
- SPD (Serial Presence Detect) chip is a chip on a RAM stick that stores information about frequencies, memory timings, and much more.
- Clock generator - generates electrical pulses of a given frequency (usually rectangular) to synchronize various processes in digital devices.
- The frequency at which the central processor operates is determined based on the FSB frequency and the multiplication factor. Most modern processors have a locked multiplier, so the only way to overclock is to change the FSB frequency.
- BSEL pins on the processor are responsible for selecting the FSB frequency and all parameters that depend on it by the chipset and TG, respectively. On the latest processors there are three such pins; they can take values of logical zero or one. Different combinations of these zeros and ones correspond to different FSB frequencies.
- A register is a functional unit that receives, stores and transmits information.
There is often a desire to increase the performance of a laptop computer. Overclocking a laptop is not much different from overclocking a desktop computer. The only thing is that it is difficult to change components in a laptop. Therefore, you need to overclock a laptop within the limits allowed by the operating system.
In order to change the value of parameters in the system, you need to find out the availability of parameters for overclocking. Turn on the laptop and go to the BIOS menu. For an HP laptop, first press the “F2” key, then select the desired item. Next, in the “Advanced” tab, look for a field called “Overclocking Mode”. Here you can explore the overclocking options. Select the percentage you want - 5%, 7% or 10%. Now the specified parameters need to be saved and the computer restarted. You should also remember that increasing performance will increase the device's power consumption.
After these steps, you will be able to see that your laptop will run faster. However, as already mentioned, do not forget that now it will consume more energy.
Greetings!
I think that there are hardly many users who would not want high speed and performance from their laptop. In this situation, it seems natural to have an undying interest in the topic of increasing performance and overclocking.
The processor plays a key role in the operation of a computer; performance and speed of performing certain tasks also depend on it. By overclocking the processor, you can achieve an increase in speed and performance of tasks on a laptop, in some cases quite significant.
This review will talk about methods for increasing the performance of laptops from a variety of manufacturers: ASUS, HP, DELL, ACER, Lenovo, MSI, etc.
Well, let's get started.
Please note that overclocking involves operating some components under stress. This can affect performance (overheating, etc.) and ultimately lead to breakdown of your existing equipment.
You do the actions described in this material at your own peril and risk.
Utilities that we will need to implement our plan:
SetFSB(overclocking program). The utility works in demo mode, but there is also a free version, which is a little older. Official website of the utility.
PRIME95– a utility whose task is to test the stability of the processor. The program is free, you can download it from the official website.
It should be noted that the above utilities can be replaced with analogues, of which there are a number. But this review will be built using exactly these utilities.
Overclocking a laptop processor using the SetFSB utility
In general, overclocking the processor installed in a laptop is not so simple - the increase in performance is often not as thorough as we would like. This is prevented by possible overheating of the processor and other components installed in the laptop.
Naturally, this scenario is initially laid down during the development of the device, because all modern processors have in their arsenal a system that prevents overheating: upon reaching a critical temperature, the processor automatically reduces performance. If this is not enough, then the laptop will simply automatically turn off (or freeze).
Yes, overclocking the processor by raising the supply voltage will not be considered in this review, because carries increased risks, especially in terms of mobile processors that are installed in laptops. And often this feature is completely blocked at the hardware level.
1) Determine the PLL chip
In order to proceed directly to overclocking, you need to find out the brand of PLL chip that is installed in the laptop.
In short, this chip is responsible for generating the operating frequency for individual components and elements of the laptop and ensures synchronization between them.
Different laptop models (including those from the same manufacturer, with a specific model range) can use a variety of PLL chips. It is impossible to single out any specific solution that is widely used by laptop manufacturers.
PLL chips are manufactured by third-party companies, the most famous of which are: STMicroelectronics, ICS, Texas Instruments, Silego, etc.
To determine the PLL chip used in your laptop, you can use the following methods:
- You need to find out the brand of motherboard installed in the laptop. You can read about how to find out the brand and name of the motherboard in the article. And then, using a search engine (for example, Google or Yandex), find out which PLL chip is installed in this motherboard.
This information is usually posted on the Internet by overclocking enthusiasts who have previously encountered the motherboard/laptop that you have. - Or you can disassemble the laptop yourself and visually highlight the necessary information from the chip. However, if you have not previously disassembled a laptop, then it is not recommended to resort to this method.
2) Specify the microcircuit and increase the frequency
Run the previously downloaded SetFSB utility. Select your PLL chip from the list in the window that appears and click the button Get FSB.
The window will display the current frequency characteristics. In the lower right corner of the utility, the current operating frequency of the processor installed in your laptop is displayed.
To increase it, check the box Ultra, and then start moving the slider to the right side. You shouldn’t get carried away with this; if you push the slider to its extreme position, the likelihood of stable operation may decrease. Start small, move the slider a few notches (literally 5 ... 20 MHz).
Then click on the button next to it Set FSB, to apply the settings.
If you did everything correctly by choosing the correct PLL chip, and the manufacturer did not block the ability to increase the frequency, etc. at the hardware level, then you will be able to watch how the overall frequency (Current CPU Frequency parameter) of the processor in the lower right corner increases.
If the laptop freezes while changing the frequency, then after rebooting, check whether the PLL chip is set correctly, the overclocking level, etc. There is a possibility that at some stage you made a mistake.
Having successfully raised the frequency of the laptop processor, you should test it for stability.
3) Testing an overclocked processor
As a rule, if the processor is overclocked and exhibits instability or overheating, then this program will detect this within 5.. 10 minutes. As a result, the computer will either freeze or display errors.
Undoubtedly, this utility can be used for testing and over a long period of time, for example, left for an hour, but in most cases this will be unnecessary.
If the testing results do not reveal any instability in the operation of the laptop, then you can try to raise the frequency by a few more points, repeating everything that was described in the second step.
And after this, naturally, it will be necessary to re-test the stability of the system. In this simple way, you can identify the maximum permissible overclocking frequency, at which the processor performance increases, but the stability of the processor and the system as a whole does not suffer.
Based on average values, an increase of 5 to 15 percent can be achieved in this way.
Brief summary
From the article we learned how to increase the frequency of the mobile processor installed in the laptop. This overclocking method is relatively safe, but it is necessary to control the temperature (you can read about this in the material) and the stability of the overclocked system as a whole.
I wish you successful overclocking!
If you have any questions, you can ask them in the comments.
Before we begin to implement the question of how to overclock a processor, a little theory. Not all processors are the same.
There is no way to increase productivity by more than 50% (10%-20% is the best option). Some can be overclocked without removing the back panel and entering the BIOS.
The laptop is too difficult to cool, and when overclocking it usually needs to be increased. The result may be opportunity - zero.
When it comes to a computer, instead of overclocking an old processor, it is better to buy a new one. Just be sure to take into account the parameters of the motherboard.
Overclocking is also called overclocking (increasing the performance of standard parameters).
In the processor, this means: voltage, multiplier and frequency. All processors have a safety margin.
Manufacturers leave them in order to increase warranty performance, or rather, so that your PC does not work at its maximum. Theoretically, it turns out that anyone can overclock.
With the right settings, you can overclock a processor running at 1.5 GHz to 2, but it’s hard to say how long it will work with these parameters.
It should also be noted that if you want to increase the speed for games, then you usually have to change the parameters and video cards.
How to overclock a processor
Its main characteristic is frequency. The FSB bus is responsible for it. The frequency is determined by the multiplier. To make it clearer, I will explain with an example.
If you set the bus to 100 and the multiplier to 10, then the actual frequency of your processor will be 1000 = 1 GHz.
The FSB frequency can be changed using programs or in . There shouldn't be any difficulties. Today there is good news for those who are trying to overclock their processor.
They are now designed in such a way that if the permissible values are exceeded, they automatically reconfigure to the default settings, in other words, a disaster should not happen.
In the BIOS, the CPU Clock is responsible for the frequency parameter. If you click on it, you will be shown the multiplier, FSB bus and clock frequency.
Now that we have become familiar with the basic terms of how to overclock a processor, let’s see what will happen in practice.
Instructions - how to overclock the processor.
Now we already know that to overclock the processor we need to raise the clock frequency, and this can be done either in the BIOS.
In this article I will show the latter as an example. We go into the BIOS.
This can be done in different ways depending on the version.
The most common, immediately after turning on the computer or laptop, quickly press the F2 or Del key. (there are many other options). Look at the picture.
After logging in, the first thing you need to do is make sure that the RAM frequency does not increase at the same time.
You can simply reduce it. Look at the picture, just keep in mind that depending on the BIOS, this parameter may be located in a different place.
Today there are already more than 6 versions of BIOS, be careful, and it is best to download a translator of computer terms, although today there is.
When you start raising the FSB, keep in mind that the memory frequency should decrease in direct proportion, or rather, remain the same as it was before all operations began.
Overclock your computer gradually - one might say step by step, all the time after that checking its operation in practice.
If it doesn’t freeze, that means good. Don't forget, you always have the option to return to the initial default settings.
