How to overclock the NVidia video card? Tips and instructions for overclocking the NVidia GeForce video card
Weak video card is the main reason for slowing down HD video, graphics in games and "heavy" programs. But there is a way out of this situation, and this is overclocking your GPU. In fact, there is nothing complicated here, but since the video adapter is a rather expensive component, you need to be careful and know all the important nuances. Let's talk to you about how to overclock the NVidia video card and what is needed for that.
Today there are a lot of controversies over whether or not to overclock the GP and how to do it. There are both supporters and opponents. But everyone agrees about one thing: if your system is not stabilized, that is, a weak processor, an outdated motherboard or little RAM, then there is no point in this, since it will not bring any visible result. In addition, overclocking needs to be done carefully, otherwise you risk burning the GP, and the case is non-warranty, so you have to buy a new one.
Under any circumstances, higher frequencies lead to excessive heat, as well as increased nutrition. Based on this, you need to increase the speed of rotation of the cooler, if necessary, change the radiator, as well as test the power supply. If the latter does not withstand the load, it will simply burn. Well, now let's take a closer look at the question of how to overclock the NVidia video card and what to look for.
Safety is the key to success
There are certain requirements that need to be fulfilled no matter what manufacturer you have. The main one is a gradual increase in frequency. The bottom line is that productivity increases in stages by 10%. So, after the next overclocking, you need to start monitoring and test the results under load. For example, start the game and see if there are “artifacts”, braking, etc. If not, add another 10% and re-test. When the first glitches appear, you need to roll back by 10%, this will be the intermediate value at which the efficiency will be maximum.
After you improve the performance of the GPU processor, overclock the video memory in the same way.In the latter case, the temperature will rise sharply. If the indicator goes beyond 90 degrees Celsius under load, you need to stop overclocking. After that you have to figure out how to overclock the video card. NVidia geforce gt 640 will work normally even if you increase its capacity by 10-30%, but the resource is reduced by about 15%, and the heating will increase by 20-30 degrees. So think twice.
Overclocking software: NVidia Inspector
This utility is specially sharpened for use on the NVidia GP. For this simple reason, it is not recommended to use the program on video adapters from other manufacturers.
We can not say about the possibilities of NVidia Inspector. The utility allows you to monitor the frequency, temperature, and fan speeds. Among the main advantages are the possibility of independent overclocking of each level of video card performance. All changes are logged, so that after testing is completed, you can read and see everything. In addition, you can change the voltage of the GPU, that is, the processor. In order for overclocking to be balanced, it is possible to increase the speed of rotation of the cooler or coolers.Thus, the program for overclocking the NVidia Inspector is completely free and is very popular. Now let's talk in detail about how to work with such software.
Step-by-step instructions for overclocking in NVidia Inspector
At the first stage, you need to start the program and click Show Overloking. After that, you will receive a notification that this event can disable the GP, but since we have decided to increase productivity, we go ahead and click "Yes". If specifically, we are interested in a section called Performance level, which in the future must be carefully configured. You will see about 6 sliders, which are responsible for power, cooling, etc. Each of them must be increased by about 5%, to begin with this will be quite enough. It is possible, of course, and more, but in this case there is a small risk of resetting the GP driver.
It is important to pay attention to such an indicator as Fan. In essence, this is the fan speed. You can manually adjust this parameter, but it is always recommended to tick Auto. Depending on the temperature, the fan will rotate faster or slower, but not fixed.At the very end, do not forget to save the changes for the NVidia geforce video card.
CPU-Z, or quality monitoring
The utility is somewhat simpler than the above option, but no worse. It is free and is freely available online. After you start it, you will be able to observe all the characteristics of your video adapter, including those that we want to slightly increase. We are interested in the frequency of the graphics core, shader units and, of course, the graphics card memory. In this utility, you can see the performance of the GP with the given parameters. To do this, you need to find the following items: Pixel fillrate, TextureFillrate, and Bandwidth.
Of course, you cannot change any parameters here, you can only observe the effectiveness of overclocking. To do this, we need the already well-known NVidia Inspector, where we will increase the parameters, and test them under load using FurMark. After about 10-15 minutes you can stop the test. If during this time there were no artifacts, and the temperature did not exceed the mark of 90 degrees, then overclocking can be considered successful. In the future, it is strongly recommended to monitor the temperature of the GP.
How to speed up NVidia video card?
In some cases, the matter is not at all in the GP, and if it is in it, then overclocking is not always necessary. For example, a dried thermal grease significantly impairs heat transfer, which leads to a rapid overheating of the radiator and, as a result, the processor.
In order to speed up the performance of your video adapter, do time cleaning from dust and replacing thermal paste approximately 1 time per year. Modern GPs can be overclocked through the BIOS, but at present this is still a rather “raw” way, so it doesn’t always fit, and a newbie can hardly cope with this. But the increase in the speed of the program method is very much for any user. But regardless of the approach chosen, it must be remembered that if the GP burns down due to illiterate overclocking, this product is no longer subject to warranty service.
Riva Tuner is simple and effective.
Let's consider the case when the system unit has only one GP. Let it be NVidia video card. When you first start you can watch two flashing triangles. The top one is designed for low-level overclocking of the GP, the bottom one is needed for working with the driver.If you have a modern video card, you will have to use the second method. It is somewhat more complicated, but effective.
After clicking on the triangle, choose your own GP and you will be able to see at what frequencies it now works (section “Overloking”). In order for us to be able to edit the frequency, it is necessary to put a tick at the top of the dialog box. After that you will see a warning window. It is recommended to select the Reboot option, that is, to restart the PC to determine the factory frequencies of the GP. If there are already standard settings, click on Detect Now.
Overclocking with Riva Tuner: continued
If you did everything correctly in the first part, then the sliders will become active, and you can move them as you like. But do not rush to do it. The fact is that we can increase the performance for 2D, which is completely useless for games, so from the drop-down window of the same menu choose “3D performance”. You see two sliders: one responsible for the core frequency, the second for the memory. Start overclocking is better from the second. It is necessary to do everything gradually and increase the performance by no more than 10% at a time. After each time, press the "Test" button to check the stability.
After you have determined the optimal memory frequency, proceed to overclocking the kernel. In this case, it is desirable to return the memory frequency to its initial position. If the picture in the game froze and hung, then restart the PC. This indicates that this frequency is dangerous. In principle, this utility for overclocking an NVidia video card is quite good and easy to use, and therefore suitable for both beginners and professionals.
As you can see, overclocking the NVidia video card is not such a difficult task. As practice shows, with the right approach, no problems arise. But if you accidentally overdo it, reset the settings to the factory settings. If this is not done, then sooner or later the GP can overheat and fail. By the way, it is strongly recommended to increase the voltage along with heating, since the graphics adapter needs more electricity when working at the limit of its capabilities.
So we talked to you about how to overclock the NVidia Geforce video card. You probably noticed that with absolute ignorance of the features of the device and the principles of the program method or the same BIOS, this venture is better left alone.This decision will be correct. It is better to contact the experts, or at least to people who are a little versed in this topic. So you, at least, do not burn your GP.
It's one thing if it's an office video adapter and costs a penny, and another when a burned-out game card costs tens of thousands of rubles, and this, you see, a lot. So be careful and attentive. Acceleration should be phased and always with testing at each stage. After that, it is advisable to install any gadget on the desktop to control the temperature of the HP. And always remember that at least some kind of video card is better than none at all. Always think twice!
