Msi auto berner: MSI Afterburner 4.6.4 Download | TechSpot

What does the manual setting of the «curve editor» do?

1. «Smooth» framerate due to stable frequency.
2. Reduced consumption by reducing the voltage.
3. Temperature reduction due to voltage reduction and, as a result, consumption reduction.
4. Speed ​​reduction of fans due to temperature reduction with equal performance.
5. Stable accelerator .

Terminology used hereinafter:
VL — voltage limit , voltage limit limit;
PL — power limit , consumption limit limit;
Emphasis on the limit (grooving) — when any of the values ​​of VL / PL exceeds the allowable values;
«Corn» — exceeding the allowable values ​​simultaneously for VL and PL;
«Saw» — constant drops (jumps) in the core frequency up / down;
«Synthetics» — usually denoted by tests focused on testing the maximum capabilities;
«Drop» — usually means a drop in frequency, temperature, result, etc.

Advice

For any manipulations with the accelerator in the MSIA program or any other, try to always activate the built-in monitoring, or keep the «Sensors» tab of the GPU-Z program in front of your eyes, then you will be able to correctly and timely respond to the consequences of your actions.

^{The main indicators are highlighted in red.}

Why is the «curve editor» better than moving the slider?

When adjusting the frequency of the video card chip through the sliders, you cannot control the voltage that is set in automatic mode for the current frequency, which always leads to limits and a constant «saw»: high consumption, high temperatures, fps drops.
PLUS : some synthetics «digest» this behavior and produce a larger result.

When adjusting the c/w editor, you can always find a voltage at which the chip frequency will be at one value and decrease only when certain temperature steps are exceeded:

^{MINUS : It takes some time to find the right voltage for the right frequency.
PLUS : reduced consumption, lower temperatures, stable fps.}

Practice

When working with a «curve» there are cases when part of the frequencies after a fixed one remains at the top and as a result the voltage you recorded «does not work», this can be leveled in two ways.

In most videos, this is done through the initial reduction of the entire «curve» and after setting the required frequency / voltage:

located above the desired point, selected with Shift + LMB pressed, after the Shift key is released and any point in the selection goes down, then click «apply» and everything falls into place:

what tasks

Via the Shift key

By holding the «Shift» key, you begin to drag the desired point up / down (the entire «curve» moves along with it), is equivalent to increasing the frequency of the main window of the program, «apply»:

^{MINUS : you have no control over voltage, hence consumption and temperature.}

Through one point

Press LMB on the selected frequency / voltage and drag up, the easiest and most convenient way to find stable matches, «apply»:

^{PLUS : You can find the minimum voltage for the desired frequency.
MINUS : sometimes takes a long time.}

Via Ctrl

By holding down the «Ctrl» key, start dragging any point up/down, thereby reducing/increasing the aggressiveness of the curve behavior, usually used in extreme overclocking, «apply»:

• Core Voltage — the voltage of the leading graphics core. Depending on the microcircuit of the supply voltage regulator, it is indicated explicitly or as an offset from the base value.
• Power Limit — sets the power consumption limit, more details at the link.
• Temp Limit — sets the temperature of the video core, exceeding which will reset overclocking — frequencies and voltage will drop to the nominal level. The graphics chip’s thermal protection system can lower them further in order to bring down the temperature of the video card.
• Core Clock — core clock of the video card.
• Memory Clock — video card memory frequency.
• Fan Speed ​​- graphics subsystem fan speed controller.

In addition to Core Voltage, the frequency value is also sometimes indicated as an offset from the nominal value.

What if the sliders are not active?

Some parameters cannot be changed when the application starts. To activate after installing the program, restart the computer, the second step is to update the graphics drivers. Download the latest versions exclusively from the official website of the manufacturer of the video card, laptop.

If Temp and Power Limit (or one) could not be enabled in the described ways, then the device does not support the technology of power management and temperature limit adjustment at the physical layer.

Core Voltage is blocked by the developer of the program in order to protect the device from the experiments of gamers. They tend to increase the parameter to the maximum in order to get an increase of a couple of fps. To unlock the graphics core voltage regulation:

1. Open Afterburner settings by clicking on the gear icon.

   Calling up configuration options to enable graphics card power management option.

2. Activate the «Unlock control…» option and save the settings.

   The control scheme should be left as standard, while the kernel power management slider can be unlocked.

3. Restart the program to apply the settings.

   The changes will take effect after the next launch of the Afterburner.

Method 2

1. Double-click the «profiles/MSIAfterburner.cfg» document stored in the executable’s directory and select «Use Application…».

   By default, the folder is stored in «Program Files (x86)».

2. Select Notepad.

   Any text editor will do.

3. Set the «UnlockVoltageControl» value to one and save the changes.

   Alternative way — Ctrl + S shortcut.

4. To enable the fan speed control slider in the settings, visit the «Cooler» tab, activate the «Enable software custom auto mode» option, click «Apply».

   Way to enable the frequency controller via program parameters.

Good to know. To fine-tune the rotation of the fan, use the curve in the graph that appears.

To unlock the card’s fan speed control, click on the «Auto» icon next to the slider and adjust it manually.

Clicking on the icon will increase the cooling efficiency (if moved to the right) or acoustic comfort (to the left).

What to do if the sliders are at the minimum or maximum level and do not move

When the sliders are at the left or right border in MSI Afterburner and do not move, unofficial overclocking should be enabled in the settings. Then restart the application.

Try to select both options in turn.

The last option to get rid of the problem is to edit the configuration file:

1. Shut down MSI Afterburner.
2. Open the «profiles/MSIAfterburner.cfg» file with a text editor as shown above.

   Record changes made.

3. Set the «EnableUnofficialOverclocking» value to one and save the changes.

Ask a question

Will reinstalling the program help unlock the sliders?

Restarting the application and computer will help.

Will MSI Afterburner work when the sliders are disabled?

It depends on what tasks are assigned to the program. If you use it as a monitoring of the graphics parameters, to regulate the frequency of the memory and core — it will.

Why does the program show the frequency incorrectly?

GDDR5 memory operates differently from GDDR4 and its predecessors. In the old one, information is transmitted twice per clock — the reference frequency. The frequency of data exchange on the bus is twice the reference, called effective.

In GDDR5, the frequency response of the bus (for example, 1000 MHz) is twice the reference frequency (500 MHz), and information is transmitted on the bus at twice the frequency. The effective frequency is equal to two bus frequencies and four reference frequencies (2000 MHz). GPU-Z will display the reference frequency and NVIDIA Inspector will display the buses.

Suddenly something doesn’t work — write, we will help you get rid of the problem. Do not forget to specify the Afterburner edition, video card model, graphics driver version, applications.

  Core Voltage slider does not move

  After installing MSI Afterburner, this slider is always inactive. This was done for security purposes. In order to fix the problem, go to «Settings-Basic» and check the box next to «Unlock voltage» . When you click «OK» , the program will restart with the user’s consent to make changes.

  Video card drivers

  If the problem persists, then you can experiment with the video adapter drivers. It happens that the program does not work correctly with outdated versions. In some cases, new drivers may not be suitable. You can view and change them by going to «Control Panel-Task Manager» .

  The sliders are at maximum and do not move

  In this case, you can try to fix the problem through the configuration file. To begin with, we determine where we have the folder of our program. You can right-click on the shortcut and see the location. Then open «MSI Afterburner.cnf» with notepad. Find entry «EnableUnofficialOverclocking = 0» , and change the value «0» to «1» . To perform this action, you must have administrator rights.

  Then we restart the program and check.

  The sliders are at a minimum and do not move

  Go to «Settings-Basic» . At the bottom, put a mark in the field «Unofficial overclocking» . The program will warn that manufacturers are not responsible for the consequences of changing the card parameters. After restarting the program, the sliders should be active.

  Power Limit and Temp sliders not active. Limit

  These sliders are often inactive. If you tried all the options and nothing helped, then this technology is simply not supported by your video adapter.

  Video card is not supported by the program

  MSI Afterburner is designed to overclock AMD and NVIDIA cards only. It makes no sense to try to overclock others, the program simply will not see them.

  It happens that cards are partially supported, i.e. not all functions are available. It all depends on the technology of each particular product.

  Thank the author, share the article on social networks.

  MSI Afterburner is the most used utility for overclocking discrete graphics cards. It also provides detailed information about the computer’s hardware and offers advanced features such as fan adjustment and performance testing. An interesting feature of the program is the ability to work with NVIDIA and AMD graphics cards of any manufacturer.

  This article will show you how to properly overclock your graphics card using MSI Afterburner. Before overclocking, you should decide whether it is possible to overclock the installed video card or not. It is worth noting that in addition to overclocking full-fledged discrete graphics, MSI Afterburner allows you to slightly overclock previous generation mobile graphics.

  Is it worth it to overclock your graphics card? Of course, for successful overclocking, you need suitable hardware and a little knowledge. Whether it is worth overclocking the video card, the user must decide based on the state of the system and the set of components.

  For those who like to play, there is often not enough power of the video card responsible for processing heavy graphics of game engines. This translates into low frame rate or FPS, jerky picture and other unpleasant things. Proper overclocking of the video card will help to partially or even completely overcome them.

  Important! Overclocking is the work of some component beyond its regular, factory capabilities. The manufacturer does not guarantee a stable state of the system under overclocking. And you also need to understand and take into account: during overclocking, the temperatures and power consumption of the PC increase. Thus, before any intervention in a slow but stable system, you need to find out whether it is worth starting at all.

  When overclocking a video card, the first thing to do is find out what kind of beast is installed inside. The free TechPowerUp GPU-Z program will help you find out everything very simply. You can see all the detailed specifications here. model ( Name ), year of release ( Release date ), GPU ( GPU, Technology, GPU clock ) and memory ( Memory type, Memory size, Bandw>) parameters.

  Parameters marked in red are to be evaluated later. With successful overclocking, the core and memory frequencies, as well as the memory bandwidth, should increase. It is the increase in these parameters that gives an increase in performance in games.

  When overclocking is not recommended

  • The older — the worse — no overclocking will help the old video card to start running modern games. And the more time has passed since its release, the less you can feel the effect. The point is in many ways: outdated technologies, a small amount of video memory, excessive gluttony and resource depletion. That when trying to overclock can easily lead to breakage.
  • Cheap video card — relatively cheap video cards are not designed for heavy games at all. Their task is to allow the user to watch videos, perform office work and surf the Internet. For them, overclocking will practically not help, and even be harmful, due to the simple design and massive savings on board components and cooling.
  • Video cards on laptops — in any laptop, even a gaming one, everything is done for the sake of size and energy efficiency — thin cases, small radiators of cooling systems, dense layout on the board. During overclocking, the system generates additional heat, with which the cooling of the laptop often cannot cope and is forced to limit its performance.
  • New to computers — if you are not very computer savvy, there is a big chance to reduce the performance of your computer. In fact, the user must understand what he is doing and why, be aware of the risks and be prepared for various consequences.

  How to properly overclock a video card

  All you need to do to successfully overclock a video card is to increase the frequency of the GPU and video memory using driver applications or other software. In this case, it is imperative to monitor the temperature and stability of the operation of these components.

  First you need to find out the current state of affairs, that is, to understand how stable the video card is before overclocking, what are the frequencies and temperatures. To do this, it is convenient to use software for stress testing, for example, you can use FurMark. It is with the help of the current program that you need to check the video card on the computer before purchase.

  In the main window, we are greeted by the name of the graphics card (1) or cards (if there are several of them in your computer, the first one in order will be tested). It should correspond to the model obtained in the GPU-Z utility. For the stress test, it is recommended to select a resolution (2), equal to the resolution of your monitor. After pressing the button GPU stress test (3) and GO , there will be a transition to the test mode, where the video card will be fully loaded.

  When a similar picture appears on the screen, you should pay attention to two sections with extremely useful information about passing the test. First of all, you need to look at the temperatures under load (2). Judging by the graph, you can see how the card gradually reached a maximum temperature of 75 C and stopped at this level. This temperature is quite acceptable and does not cause any concern.

  Attention! If before overclocking, the temperature of the video card in this test is more than 80C, then there is a risk of overheating and instability after increasing the frequencies. In addition, at elevated temperatures, the risk of damage to the GPU and memory increases, as does the wear of the fans. And also if, after starting the test, the temperature graph rises sharply more than 90C, the test must be disabled (ESC key), as there are obvious problems with the cooling system.

  The appearance of flickering, various distortions, lines, color changes or blackouts of the display and other abnormal effects indicates a malfunction of the video card, even if everything works fine in other applications or games. Overclocking such a card in any case is categorically contraindicated.

  In section (1) you can track the main parameters of the test (resolution, anti-aliasing level) and the card under load (core, memory (3) and fan speed, test time and average number of frames per second (4) that the card can give It is the average FPS that is needed to compare performance before and after overclocking, so you need to remember or write it down. 0004

  How to overclock NVIDIA MSI Afterburner

  Having successfully completed all the steps in preparing for overclocking, you can start overclocking using a simple algorithm. It is enough for the user to raise the frequency of the video card core. Then immediately check the stability of overclocking and the temperature in FurMark. However, depending on the manufacturer of the graphics chip, this should be done differently.

  NVIDIA graphics card can be overclocked most conveniently with MSI Afterburner by MSI. If the card is from AMD, then in addition to MSI Afterburner, overclocking can be done through a standard component installed with WattMan drivers.

  In the main Afterburner window, we are interested in 3 main parameters: Power Limit (1), Core Clock (2) and Memory Clock (3). As you can see in the figure, the frequencies are +0, and the power limit is 100%, which means that the card is not overclocked.

  And you should also pay attention to the parameter Fan Speed ​​ (4), that is, the speed of the video card fan. For easy overclocking, it is worth leaving the operating mode Auto .

  First of all, it is worth freeing the card from current and power consumption restrictions by moving the slider Power Limit to the maximum to the right. Now the video card will not underestimate its frequencies to match the declared power.

  You can start overclocking by raising the value of Core Clock to 60 MHz and pressing the Apply button at the bottom of the window. Then you should run FurMark and check the result. You need to look at the temperature, core frequency (memory frequency, when overclocked) and FPS, which should increase. After making sure that the video card is stable, you can again move on to raising the frequency.

  At +120 MHz, subject froze for a while, even without load. In this case, it is better to press the button Reset and reset all default values. Next, you should reduce the overclocking frequency to +90 MHz and check the stability. After launching FurMark, the PC freezes for a minute with a black screen, which means that overclocking needs to be reduced further. At +65 we have stable operation at higher frequencies.

  First, let’s go back to GPU-Z and check the parameter GPU Clock , which increased just by the 60 MHz added in the MSI Afterburner program. Along with the frequency, the speed of pixel and texture filling also increased, which confirms the success. In FurMark, you can also see the performance boost by evaluating the increased GPU frequencies and average frames per second.

  On the example of overclocking the GeForce GTX 970 graphics card from NV >Total, after unlocking the power limit and increasing the frequency by 65 MHz, that is, by 8.5%, the increase in FPS was 8 frames, which is equal to 7.5%. At the same time, the temperature rose to 76C, which is quite normal, due to easy overclocking, and does not arouse suspicion.

  Many people ask: « How to overclock a video card using msi afterburner?»

  Before overclocking the card, you need to pay attention to its cooling. It is this process that is relevant for launching advanced games that create a heavy load on the video processor. If the card has a weak cooler, then it is not recommended to overclock it, otherwise you can completely disable the element.

  Also, do not overclock video cards installed in laptops. If we turn to statistics, then the percentage of video cards burned during overclocking in the case of laptops is greater than in the case of a PC. Finally, not all cards support the overclocking feature.

  What else needs to be considered?

  Additionally, before overclocking, you can pay attention to the fact that not all games completely consume the resources of the video card. For example, in the same StarCraft 2, a significant share of the load falls on the processor. Thus, it is unlikely that it will be possible to improve the performance of the game if you start accelerating the video card.

  Overclocking process

  The card is often accelerated using MSI Afterburner. This is a program designed to overclock a video card, which leads to an improvement in the performance of the computer and the game as a whole.

  A feature of the process is that you do not need to enter the BIOS settings of the system and change the voltage. Everything will be done by the program, and the most important thing is to learn how to use it.

  The process consists of several steps, each of which will be discussed in more detail below. The procedure is based on tracking the state of the video card as it is loaded and the corresponding change in device parameters.

  The first step is to select the settings

  The first step is to start the program. The initial screen will appear before your eyes. Further, the sequence of actions is as follows:

  1. You need to enter the menu. The menu looks like a gear on the top bar.
  2. In the column titled «Select Leading GPU», select the graphics card to overclock. If two cards are installed on the computer, you will need to click the checkbox to synchronize the settings of the same GPU.
  3. After that, you will need to check one more checkbox. It is placed in the «unlock voltage monitor» column.
  4. Then you need to go to the «Cooler» tab and enable automatic mode. Only then will the program allow you to set the relationship between speed and temperature.
  5. Finally, the last action of the step is to change the points on the chart that appears. The graph will just display the relationship between speed and temperature.

  It should be noted that the maximum speed cannot be set immediately, otherwise the cooler will immediately fail.

  The second step is adjusting the sliders

  The second step when overclocking the video card using MSI Afterburner means:

  1. Moving the Core Clock slider to the right side. It is desirable to move it by about 10-20 MHz.
  2. Confirmation of the action with the «Apply» button.
  3. Moving the Memory Clock slider also to the right side up to 20 MHz.
  4. Action confirmation.

  Thus, in the first stage, the numbers should be 921 and 2072 MHz.

  The third step — testing

  After the settings for the video card have been made, it is necessary to check its performance. To do this, you will need to run a fairly powerful game on your computer in windowed mode and play for about 2 hours, not forgetting to monitor the state of the graph.

  If during the game you did not notice any distortion on the screen in the form of multi-colored or red stripes, you can move the cursor again by changing the frequency. And further in the same way:

  • start the game;
  • testing for two hours;
  • performance tracking;
  • frequency increase.

  As soon as screen distortions begin to appear, the process must be stopped. You will also need to close the game and lower the frequency.

  It will not be possible to answer at what stage the video card will increase, since in any case the indicator will be individual. Some stop the process at the second rise, some overclock the card to the third and even the fourth rise in temperature.

  However, when increasing the speed of the card, it should be taken into account that if it is used for a long time in this state, it will simply burn out, and then you will have to buy a new one. That is why it is so important to ensure the cooling of the device.

  Stress test

  If you don’t have any powerful games at hand, but you want to check the operation of the card, then you can take benchmarks or use hardware tests for testing. So, for example, MSI Kombuster, which monitors the temperature and overall load of the video card, will become a good utility.

  Data logging during the test will allow you to overclock the card to an acceptable speed and continue working, taking care of the cooling of the device. But it is worth noting that the so-called stress test does not give such accurate results as a test of the game would give.

  Saving settings

  When the process is completed and the card is accelerated to the maximum, you will need to save the current frequencies and speed of the cooler.

  For this you need:

  1. Press the Startup button.
  2. Press the save profile button. To do this, you need to select any of the highlighted 5 slots. It is best to choose the first one.
  3. Go to settings-profiles and in the 3D-profile column check the display of the received parameters.

  If other parameters are displayed in the tab, it is recommended to change them by entering the required numbers or by testing on a new one.

  Possible problems

  Not always possible with msi afterburner overclock the video card correctly. There may be problems in the process. For example, manufacturers of some video cards pre-install a block on their devices that prevents acceleration.

  To get rid of this block, you need to find the MSIAfterburner.cfg file and open it in notepad. Next you need:

  1. Find the line UnofficialOverclockingEULA.
  2. Write a sentence after the «=» sign: I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it.
