Как изменить вольтаж на процессоре

Be it a laptop or a desktop PC, the performance of your CPU is crucial to the way the device works, and can impact just about everything you do. Although overclocking is the most common CPU tweak that enthusiasts perform, modern chips can also benefit from undervolting.

Undervolting the processor involves lowering its operating voltage. This can be done by just about anyone through the use of software. Lowering your CPU’s voltage should result in a few benefits, such as lower power consumption and temperatures, without affecting its performance in any major way — and in some cases it might even improve it. If you want to learn how to undervolt your CPU, keep reading — we’ll walk you through it in a few easy steps.

What is CPU undervolting?

Undervolting your CPU refers to the process of lowering the amount of power that your processor receives. On paper, this may not sound like a good idea, but it actually brings more benefits than it brings risks. When done correctly, undervolting can help your processor function well without getting overwhelmed, and this, in turn, affects the performance of your entire computer.

As your CPU draws less power, you gain more than just small savings on your next power bill. Undervolting also lowers the temperatures generated by your processor, may potentially reduce the strain on it over time, and for laptop users, it may have beneficial effects on your battery life.

Undervolting is typically mostly done on Intel processors. This is because modern AMD CPUs, such as the Ryzen 5000 series, have a different architecture. As a result, they often have lower power requirements than Intel, to begin with. However, if you have an AMD CPU that is running a little hot, you could still try the steps we will go over below.

The processor is not the only component you can undervolt. You can also undervolt graphics cards (GPU) to achieve similar results — lower power consumption, lower temperatures, and stable performance. It’s okay to undervolt both the CPU and the GPU, but this is done separately and in different programs. If you want to tackle that next, check out our guide on undervolting the graphics card.

Undervolting your CPU is a fairly easy process, although at first, it might seem daunting — if only due to the vast number of options available in the software that’s most commonly used for it. However, with our guide, anyone can do it.

Undervolting vs underclocking vs overclocking

If you’re not very familiar with the term, undervolting may be easy to confuse with underclocking or even overclocking your CPU, but all three of these things are different.

Underclocking refers to lowering your processor’s frequency. While this does usually result in lower temperatures and power draw, it doesn’t actually do anything good for your computer’s performance. As you lower the clock speed, your CPU will be forced to throttle its own performance and won’t put out the kind of performance you’d like to see.

Overclocking is the exact opposite of underclocking, meaning you’re pushing your computer’s clock speed past its base frequency. Most modern processors come with a base frequency and boost/turbo frequency, but overclockers can hit speeds even higher than the advertised numbers. When done correctly, this can improve your processor’s performance at the cost of higher power consumption and higher thermals. To some extent, you can undervolt while overclocking, but your mileage may vary.

Overclocking should be done carefully. Not every processor supports overclocking, and you should approach it with a degree of caution on the ones that do support it. We have a handy guide that helps you choose whether you should overclock your CPU, and once you decide to go ahead and do it, make sure to follow our tutorial on how to overclock your processor.

Is undervolting the CPU safe?

Undervolting your CPU is usually safe. That is not to say that it can’t be done wrong, though. If you happen to undervolt your processor too much, your computer may experience instability, crashes, and lowered performance. Most common issues include the blue screen of death (BSOD) and freezes.

Undervolting is a bit of an art form — you should never do too much all at once. It’s better to take things step by step and slowly work your way toward a certain voltage than to overdo it and accidentally cause a crash.

Fortunately, undervolting your CPU can easily be reverted if something goes wrong. You’ll simply have to redo the steps and adjust the voltage to a slightly higher number until your computer is stable once again.

In many cases, instead of being risky, undervolting is actually the safest thing to do. Laptops and small-form PCs are a good example of why undervolting is helpful. As the components are packed closely together, temperatures are often an issue, and overheating happens all too often. Undervolting your CPU can be one of the ways to address that problem, and if it works, you’ll be giving your processor a boost to its lifespan and its performance.

Prepare for undervolting

You’re free to try out a few different programs for undervolting, and we’ll go over all of them in our full guide below. However, regardless of the method you use to undervolt, the preparation and monitoring will always be the same. In order to know how much you can undervolt your CPU, and to know whether you were able to achieve an improvement, you should first test your processor.

Step 1: Download a benchmarking program. You will use it periodically throughout and after your undervolting attempts.

A good way to test your CPU is to use CPU-Z, but there are other programs that can do this as well, so feel free to use software of your own choice. Make sure that it will be able to put your processor through a stress test.

Step 2: Open up CPU-Z and then move on to downloading another program: HWMonitor. This program will help you keep track of both your temperatures and your voltage while you tinker with it.

Step 3: With HWMonitor running, run your CPU-Z benchmark and take note of the figures that HWMonitor will be showing.

You want to take special note of the temperatures of all your cores as well as the maximum voltage they reach during the benchmark. It’s best to write this down so that you don’t forget. This will be your starting point from which you will begin your undervolting journey.

With both programs running, move on to the next section of our guide, in which we will show you all the ways to undervolt your CPU.

How to undervolt your CPU using Throttlestop

If you’ve decided to give undervolting a try, follow all the steps below to achieve the desired results. All you’ll need is a computer with an internet connection to download the program we will use for undervolting. In this section, we’ll cover using TechPowerUp’s tool called Throttlestop.

Throttlestop mainly works on Intel, but in theory, it should work on AMD too. If you’re running into issues on your AMD processor and can’t get the program to work, check out our other options below.

Step 1: First, you need to set up Throttlestop. Download it directly from TechPowerUp’s website. The program is only available on Windows, and usually, two versions are available: Beta and the latest stable version. It’s better to use the stable version if you’re unfamiliar with the program.

Unzip the file and run Throttlestop.exe. You will be presented with a warning stating that the software can make significant changes to your CPU. It’s true that it can, but we’re not going to do anything particularly dangerous, so press OK and proceed.

Step 2: Once you run Throttlestop, you’ll see many options as well as an overview of your processor’s current temperatures. Unless you’ve ever tried undervolting before, these settings will be your baseline — this is what your processor came out of the box with.

It’s worth noting that as you proceed, you’ll be making changes to these settings, but it’s quite easy to go back to this initial state.

You can revert the changes at any time by locating your Throttlestop folder and finding the file named «Throttlestop.ini». To go back to your previous settings, simply delete or rename the file, shut down your computer, and then start it up again.

For now, let’s undervolt.

Step 3: In the main Throttlestop window, on the left side, locate Speed Shift — EPP and tick that option. On Intel processors, this enables the Speed Shift technology, also known as Hardware Controlled Performance. It’s responsible for improving performance and responsiveness by letting the processor quickly switch to the best voltage/frequency option given the current workload.

Locate FIVR and press it. This will open up a new window with a whole lot of settings. We’re only going to need to tweak a few.

Step 4: In the middle column titled «FIVR Control,» locate CPU Core Voltage and tick the first option right underneath: Unlock Adjustable Voltage. Other than that, we’re also going to tweak CPU Core, CPU Cache, and Intel GPU. Unsurprisingly, if you’re trying to use this program on an AMD processor, this last option may be greyed out or unavailable to you.

Start by ticking some necessary boxes. Make sure CPU Core is selected, and also Adaptive a little under that. The next step will be to start undervolting.

Step 5: In order to undervolt your CPU, you need to adjust the Offset Voltage. You should be doing this in small increments and the final amount depends on your processor. Older CPUs can struggle with a bigger undervolt. Meanwhile, modern processors such as Intel Alder Lake and similar generations can handle a bigger power adjustment, especially seeing as they consume a whole lot more power in the first place.

You can start by adjusting the millivolt (mV) value by a larger amount. This will depend on your chip, but -50mV should be a safe starting point. If your PC proves to function well with that, you can go back and redo these steps to lower the voltage even further.

Once you’ve adjusted the offset voltage, switch the selection at the top to CPU Cache and adjust the undervolt to the same value as CPU Core. Lastly, pick Intel GPU and undervolt it slightly if you want: Anywhere in the 25-50mV range should be fine. However, it’s okay to skip Intel GPU if you experience stability issues later on, as it doesn’t do very much for your temperatures and voltage compared to the other settings.

Once you’ve adjusted everything, press Apply. If your computer doesn’t immediately crash (which can happen, but don’t worry if it does — you’ll just have to go easy on it next time), you should also select OK — Save Voltages Immediately and click Apply once again.

Step 6: It’s time to put your new voltages to the test and see whether your laptop or desktop remains stable when undervolted.

Run your CPU-Z benchmark and watch the temperatures/voltages in HWMonitor carefully. Compare these values to the ones you achieved prior to undervolting. You should already see an improvement.

If your computer makes it through the benchmark without crashing, you can perform a few more quick tests to ensure everything is fine:
* If you’re using a laptop, run the benchmark with the laptop unplugged (using up battery life)
* Restart the computer, put it to sleep, and wake it up
* Run every piece of software you usually have open. If you tend to play games while using Discord and Google Chrome, do that, but make sure you’re doing a lot of it — really try to stress your PC.

Assuming everything went fine, you can go back and repeat the above steps. This time, undervolt in smaller 5-10mV increments. You’ll eventually hit a wall and start experiencing crashes as you test your computer (or even before that point). This means it’s time to go back, bring your voltage slightly higher, and stick to the last point where everything was stable even when your computer was performing at 100%.

Step 7: This is an optional step that only applies to laptop users. However, if you’re on a desktop, you can consider doing this too if you feel you have any need for it.

You might want to set up two profiles for your Throttlestop: One for when your computer is plugged into the wall socket and one when you’re running on battery. As mentioned above, these undervolting values may be different and you may have to scale up or down depending on whether you’re plugged in or not. As such, it’s useful to have two different profiles to make sure you’re undervolting correctly.

You can set up the profiles by going back to the main Throttlestop window and clicking Options. Desktop users might want to do this for various reasons, but mostly, this applies to laptop users with a concern for their battery life.

In Options, on the right-hand side, you’ll find AC Profile and Battery Profile. Tick both boxes. Leave your AC Profile as number one and adjust your Battery Profile to number two. Click OK to save. Throttlestop will automatically adjust these profiles based on whether your computer is plugged in or not.

Now, when you go back into FIVR, you’ll be able to choose settings for each profile. Your AC Profile should be the one with the highest performance and the lowest undervolt. For your Battery Life profile, you can and should undervolt as much as possible in order to save battery life.

Step 8: For all its virtues, Throttlestop does have some flaws. To name one, it doesn’t automatically run these profiles when you start up your PC again. It also stays in the taskbar instead of the notification area unless you change a couple of settings. In this final step, you’ll set up Throttlestop to be always on, but minimized.

In the main Throttlestop window, click on Task Bar on the left side. Next, access Options, and select Start Minimized. Lastly, select Minimize on Close, and save with OK.

To make sure Throttlestop is on whenever you power up your PC, you’ll need to play with some Windows settings instead of the app itself. To do so, click the Windows logo on your taskbar or press the Windows key on your keyboard. Type in Task Scheduler into the search bar. Right-click the app and select Run As Administrator.

In the Windows Task Scheduler, navigate to Create Basic Task on the right-hand side. Name it Throttlestop and click Next when you’re ready.

On the left-hand side, click on Trigger. Choose When I Log On. Click Next and switch to Action, then select Start A Program, and navigate to your Throttlestop.exe file. Click Open. Select the option that will make it so that the properties dialogue for the task will open when you click Finish.

Enter Properties and make sure you select Run With Highest Privileges. Click OK to save. From now on, Throttlestop will open at startup and execute these settings each and every time.

How to undervolt your CPU with AMD Ryzen Master

If you own an AMD processor, Throttlestop may not work for you. Fortunately, you can still undervolt your processor if you so wish, but you’ll have to use a different program: AMD Ryzen Master. You can download it directly from AMD.

Before you download it and try to undervolt your processor, make sure that your CPU is supported. Any processor older than the Ryzen 2000 series will not work with this program. In addition, if you’re using a laptop equipped with an APU, you won’t be able to use this either.

AMD Ryzen Master is a program that lets you overclock, adjust power modes, overclock the integrated GPU, stress test your CPU and RAM, and more. Undervolting in AMD Ryzen Master is an intuitive process, and it’s a fair deal less scary than overclocking.

AMD fans can also use the automated overclocking and undervolting tool Clock Tuner, by 1usmus, for similar results.

Step 1: In the main Ryzen Master screen, navigate toward the bottom-left corner and switch to Basic View. You can play around with the settings in this full overview, but Basic Mode gives you access to what you need: CPU voltage. You can also switch between profiles if you’d like to have separate settings for each one.

Step 2: From here, undervolting is easy. Open up CPU-Z and HWMonitor, check your current voltages and temperatures while running a CPU benchmark, and write down the values.

Go back into Ryzen Master and try to lower the CPU Voltage (Volt) value. Much like with Throttlestop, you can start bigger with -50mV. Click Apply & Test to check whether this voltage works for your PC. You should also test it for yourself by running the benchmark yet again, tracking voltage and temperatures, and keeping a keen eye out for any crashes.

If the new setting works out, go back in and lower it in 5-10mV increments until you’re starting to experience issues or you’re satisfied with it. Click Apply & Test after each attempt and run all your tests to make sure the voltage is actually sustainable under duress.

Once you’re all done, you won’t have to re-apply these settings each time. They will stay this way until you decide to change them. You can always reset the settings by clicking Default in the top-right corner of the AMD Ryzen Master Basic View.

Keeping an eye on your CPU’s temperatures is an important step in undervolting and overclocking. For more help on monitoring your processor, check out our guide on how to check your CPU temperature.

Как понизить напряжение процессора через биос

Под термином «разгон» большинство пользователей подразумевает именно увеличение рабочих характеристик центрального процессора. В современных моделях материнских плат эту процедуру можно проводить в том числе из-под операционной системы, однако самым надёжным и универсальным методом является настройка через BIOS. Именно о нём мы сегодня и хотим поговорить.

Разгоняем CPU через BIOS

Перед началом описания методик сделаем несколько важных замечаний.

• Оверклокинг процессора поддерживается в специальных платах: рассчитанных на энтузиастов или геймеров, поэтому в бюджетных моделях «материнок» такие опции зачастую отсутствуют, ровно как и в БИОСах ноутбуков.
• Разгон также увеличивает процент выделяемого тепла, поэтому перед процедурой увеличения рабочих частоты и/или вольтажа строго рекомендуется установка серьёзного охлаждения.

Собственно настройка БИОС начинается со входа в оболочку интерфейса. Если вы не знаете, каким образом это совершается на вашем устройстве, воспользуйтесь руководством по ссылке далее.

Внимание! Все дальнейшие действия вы совершаете на свой страх и риск!

Текстовые BIOS

Даже несмотря на популярность решения UEFI, многие производители по-прежнему используют вариант с текстовым интерфейсом.

AMI
Долгое время решения от компании American Megatrends предоставляли широкий функционал по разгону процессоров.

Войдите в интерфейс микропрограммы, после чего переходите на вкладку «Advanced». Используйте опцию «CPU Configuration».

После этого перейдите к параметру «Ratio CMOS Setting». Числовое значение в этой опции – множитель, которым руководствуется процессор при установке частоты. Соответственно, для большей производительности следует выбирать более высокий множитель.

Далее переходим к пункту «CPU Frequency». Здесь задаётся минимальное значение, от которого работает упомянутый выше множитель. В некоторых вариантах частоту можно прописать вручную, но в большинстве решений доступны фиксированные значения. Соотношение тоже понятное: чем выше минимальная частота, тем больше будет максимальная, учитывая множитель.

Также нелишним будет настроить питание – переходите к пункту «Chipset Configuration».

Перейдите к опциям вольтажа – памяти, процессора и питания. Универсальных значений нет, и устанавливать их нужно исходя из спецификаций и возможностей компонентов.

Award

После входа в БИОС перейдите к разделу «MB Intelligent Tweaker» и раскройте его.

Как и в случае с AMI BIOS, начать разгон стоит с установки множителя, за это отвечает пункт «CPU Clock Ratio». Рассматриваемый БИОС удобнее тем, что рядом с множителем указывает реально получаемую частоту.

Для настройки стартовой частоты множителя переключите опцию «CPU Host Clock Control» в положение «Manual».

Далее воспользуйтесь настройкой «CPU Frequency (MHz)» – выделите её и нажмите Enter.

Пропишите желаемую стартовую частоту. Опять-таки, она зависит от спецификаций процессора и возможностей материнской платы.

Дополнительная конфигурация вольтажа обычно не требуется, но при необходимости этот параметр тоже можно настроить. Для разблокировки этих опций переключите «System Voltage Control» в позицию «Manual».

Настройте вольтаж отдельно для процессора, памяти и системных шин.

Phoenix
Данный тип микропрограммы чаще всего встречается в виде Phoenix-Award, поскольку уже много лет бренд Phoenix принадлежит компании Award. Поэтому настройки в данном случае во многом похожи на упомянутый выше вариант.

При заходе в BIOS используйте опцию «Frequency/Voltage Control».

Первым делом установите требуемый множитель (доступные значения зависят от возможностей CPU).

Далее задайте стартовую частоту посредством ввода нужного значения в опции «CPU Host Frequency».

Если нужно, настройте вольтаж – настройки находятся внутри подменю «Voltage Control».

Обращаем ваше внимание – нередко упомянутые опции могут находится в разных местах или носить иное название — это зависит от производителя материнской платы.

Графические UEFI-интерфейсы

Более современным и распространённым вариантом оболочки микропрограммы является графический интерфейс, взаимодействовать с которым можно также посредством мыши.

ASRock

Вызовите БИОС, после чего переходите ко вкладке «OC Tweaker».

Найдите параметр «CPU Ratio» и переключите его в режим «All Core».

Затем в поле «All Core» введите желаемый множитель – чем больше будет введённое число, тем большей будет полученная в результате частота.

Параметр «CPU Cache Ratio» следует установить кратным значению «All Core»: например 35, если основное значение составляет 40.

Базовую частоту для работы множителей следует установить в поле «BCLK Frequency».

Для изменения вольтажа при необходимости прокрутите список параметров до опции «CPU Vcore Voltage Mode», которую нужно переключить в режим «Override».

После этой манипуляции станут доступны пользовательские настройки потребления процессора.

ASUS

Опции разгона доступны только в продвинутом режиме – переключитесь на него с помощью F7.

Переместитесь во вкладку «AI Tweaker».

Переключите параметр «AI Overclock Tuner» в режим «XMP». Убедитесь, что функция «CPU Core Ratio» находится в положении «Sync All Cores».

Настройте множитель частоты в строке «1-Core Ratio Limit» в соответствии с параметрами вашего процессора. Стартовая частота настраивается в строке «BCLK Frequency».

Также установите коэффициент в параметре «Min. CPU Cache Ratio» – как правило, он должен быть ниже множителя на ядро.

Настройки вольтажа находятся в подменю «Internal CPU Power Management».

Gigabyte

Как и в случае с другими графическими оболочками, в интерфейсе от Gigabyte нужно перейти в расширенный режим управления, который здесь называется «Classic». Этот режим доступен по кнопке главного меню или по нажатию на клавишу F2.

Далее перейдите в раздел «M.I.T.», в котором нас интересует в первую очередь блок «Advanced Frequency Settings», откройте его.

Первым делом выберите профиль в параметре «Extreme Memory Profile».

Далее выберите множитель – введите подходящее по спецификациям число в пункте «CPU Clock Ratio». Также можете установить значение базовой частоты, опция «CPU Clock Control».

Настройки вольтажа находятся в блоке «Advanced Voltage Control» вкладки «M.I.T.».

Измените значения на подходящие чипсету и процессору.

MSI

Нажмите клавишу F7 для перехода к продвинутому режиму. Далее воспользуйтесь кнопкой «OC» для доступа к разделу оверклокинга.

Первый параметр, который следует настроить для разгона – базовая частота. За это отвечает опция «CPU Base Clock (MHz)», введите в неё нужное значение.

Далее выберите множитель и введите его в строке «Adjust CPU Ratio».

Убедитесь, что параметр «CPU Ratio Mode» находится в положении «Fixed Mode».

Параметры вольтажа расположены ниже по списку.

Заключение

Мы рассмотрели методику разгона процессора через BIOS для основных вариантов оболочек. Как видим, сама по себе процедура несложная, но все требуемые значения необходимо знать в точности до последней цифры.

Отблагодарите автора, поделитесь статьей в социальных сетях.

Решил написать небольшой FAQ, как разогнать ЦП компьютера, проверить его после разгона на отказоустойчивость.

Мне всегда хотелось разогнать свою «малышку» хотя бы на чуть-чуть, но увы на стареньком Celeron 668 Mhz много не добьешься =) Потом появился AMD Athlon 64 3000+. Тогда и решил попробовать — кулер был хороший для охлаждения.

К сожалению скриншотов тех не осталось, но разогнал я до 2,4 ГГц с 1.8 ГГц. Для меня это был результат. Сейчас же стоит AMD Phenom II x4 960T, но разгоном я пока сильно не занимался, немного разогнал с 3.0 до 3.4 ГГц.

Разгон системы — вполне опасная вещь, если не знать куда лезешь и что нажимаешь. Продавцы не дают гарантию на разгон, В случае, если что-то сломается или выйдет из строя, по гарантии нам никто ничего не обменяет. Разгон — дело выбора. Все манипуляции с компьютером проводимые Вами не входят в условия гарантии! Вы делаете это на свой страхи риск!

Ну что же, хватит предысторий, начнем!

Я буду приводить инструкции на своей конфигурации компьютера, надписи могут отличаться, но суть одна.

Часть 1. Подготовка|Выбор комплектующих

Уровень успеха разгона очень сильно зависит от комплектующих системы. Для начала потребуется процессор с хорошим потенциалом разгона, способный работать на более высоких частотах, чем штатно указывает производитель. Для разгона процессора важно, чтобы другие компоненты тоже были подобраны с учётом этой задачи. Довольно критичен выбор материнской платы с BIOS, дружественным к разгону.

Температура и прочие характеристики

Перво-наперво нужно знать максимально рабочею температуру процессора — максимально допустимая у меня ≈ 80-90 °C.

— необходимо знать множитель процессора;

Материнская плата и ОЗУ

При разгоне необходима хорошая материнская плата и память.

Материнская плата должна обеспечивать достаточно большой набор функций в BIOS, включая поддержку Advanced Clock Calibration (ACC), а также прекрасно работать с утилитой AMD OverDrive, что важно для выжимания максимума из процессоров Phenom.

Подбор правильной памяти тоже важен, если вы хотите достичь максимальной производительности после разгона. При возможности устанавливайте высокопроизводительную память, в зависимости от вашей материнской платы.

У меня — ASUS M4A87TD-EVO | Kingston DDR3 2x1024mb

Охлаждение ЦП:

Прежде чем задуматься о разгоне — вы должны понимать, что разгон дело не простое и «горячие». Что бы не испортить систему необходимо хорошее охлаждение, которое стоит не то что больших, но все таки денег.

Так же, лучше открыть крышку корпуса, что бы обеспечить отток горячего воздуха (у многих стоит не один и не два кулера в системе, но лишний отток все равно не помешает)

Термопаста — специальный слой теплопроводящего состава между охлаждаемой поверхностью и отводящим тепло устройством.

Я менял ее один раз, потому что процессор стал плохо отдавать тепло и сильно греться (AMD Athlon 64 3000+).

Сильно дорогую я не покупал. Купил пасту «Титан», аккуратно нанес ее на процессор и прикрепил радиатор (об этом я расскажу в следующем сообщении).

Термопаста очень важна! Чем лучше она качеством, тем лучше она будет проводить тепло к радиатору и следовательно тем меньше будет температура ЦП.

Но можно сделать небольшой разгон и на боксовом кулере, но не ждите много — увеличение частоты на 30-60 Мгц, это уже разгон. — Если у Вас установлен боксовый кулер, то в разгоне мы не много ограничены — охлаждения может не хватить на многое.

Блок питания (БП)

БП Должен быть стабильным, обеспечивающий стабильные уровни напряжений и достаточный ток, чтобы справиться с повышенными требованиями разогнанного компьютера. Слабый или устаревший блок питания, загруженный «под завязку» может испортить все наши старания.

У меня — OCZ 500W

Как рассчитать.

Тактовая частота CPU = базовая частота * множитель CPU;

частота северного моста = базовая частота * множитель северного моста;

частота канала HyperTransport = базовая частота * множитель HyperTransport;

частота памяти = базовая частота * множитель памяти.

По этой части вроде все.

Что такое разгон?

Разумеется, бездумно жать кнопки — это не правильно. Нужно знать к чему приведут все эти нажатия. Прежде чем нажимать, нужно понимать для чего ты нажимаешь, и что после этого будет. Опасность разгона сильно преувеличена — но не ничего не возможного! Есть вполне реальная вероятность вывести компьютер из работоспособного состояния. Попросту — детали перегреются и начнут плавиться.. И никто по гарантии нам их не поменяет! Я думаю, что этот блог читают умные люди,и следовательно будем считать я Вас предупредил!

Разгон или оверклокинг (от англ. overclocking) — повышение быстродействия компонентов компьютера за счёт эксплуатации их в форсированных (нештатных) режимах работы.

Разгон сводиться к повышению тактовой частоты процессора.

Выбор: как разгонять?

В настоящее время компьютер можно разогнать посредством программ, работающих из под системы.

Так же есть специальные программы для матерински плат, на примере ASUS TurboV EVO

Так же можно разгонять систему из BIOS, оперируя настройками оттуда.

BIOS — basic input/output system — базовая система ввода-вывода.

BIOS многолик — есть Phoenix, AMI прочие версии. Но суть одна — по названиям можно догадаться что за функция.

К сожалению я не смогу предоставить своих фотографий, так как нету камеры.а на телефон фоткать — слишком убого получается.. Извиняюсь что нет своих фотографий, но то что я нашел в хламе друзей не сильно отличается от моего, да и вообще от всех M/b.

Представленная мне плата — ASUS M3A78-T

AMI BIOS — M4A87TD

Все меню я рассматривать не буду, Нас интересует только разгон.

Во-первых, плата ASUS M3A78-T позволяет изменять частоту HTT в диапазоне от 200 МГц до 600 МГц с шагом в 1 МГц. Во-вторых, пользователь может поменять множитель шины HT (HyperTransport):

В-третьих, можно изменить множитель контроллера памяти:

Для того что бы разогнать ЦП необходимо увеличивать частоту Шины процессора. Если не стартует после этого — увеличиваем напряжение на процессор.

Все это делается в меню Advanced

CPU Frequency — собственно частота. дефолотное значение на всех компьютерах, с которыми я работал — 200

Processor Frequency Multiplier — множитель. может стоять — Auto, x4, x15.

Processor Voltage — Вольтаж процессора обычно стоит на Auto или 1.4

Processor-NB Frequency Multiplier — множитель контроллера памяти.

Пользователям современных плат (например все та же ASUS M4A87TD EVO) можно просто нажать кнопочку и система сама подберет оптимальные настройки разгона 🙂

ИТОГИ: Проверяем стабильность

Ну вот, мы разогнали процессор, теперь нужно проверить его на стабильность (отказоустойчивость). Это позволит понять нам, справляется ли ЦП с возложенной на него нагрузкой. Во время теста — если «все так плохо», компьюер может перезагрузиться, уйти в BSOD или попросту зависнуть. Это значит , что компьютер после разгона будет сбоить. Возвращаемся в BIOS и понижаем частоту и вольтаж процессора. запускаем, проверяем — если все нормально оставляем. Если нет то опять в БИОС и проделываем тот же фокус с частотой шинымножителемвольтажем процессора.

Мониторить температуру во время теста обязательно!

Для этого необходимы программы:

Мониторинг данных датчиков:

FanExpert, CPU-Z, AIDA64Everest, AMD Over Drive.

Для тестирования системы необходимы:

LinX, S&M, AMD OverDirve.

Запускаем тесты, смотрим температуру.

Собственно все:) Прошу строго не судить, сильно и жестоко не критиковать.
