Tip 1: How to reduce the frequency of a video card
Each discrete graphics card has its own frequencyprocessor and memory. In many respects the performance of the motherboard depends on these frequencies. But sometimes they need to be reduced, for example, if the video card for a certain period does not work in 3D mode. Also at lower frequencies, the board will consume less power, its temperature will drop, accordingly, the cooler's rotation speed will be lower and it will work quieter.
You will need
- - CATALYST Control Center 12.1 for ATI Radeon graphics card owners;
- - program RivaTuner for owners of video cards nVidia.
Instructions
1
Owners of ATI Radeon graphics cards can reduce the frequency with the help of a proprietary settings tool Video cards CATALYST Control Center. The CATALYST Control Center tool is included with the video card drivers. Usually, during the installation of the driver, this program is installed. If the application on your computer is not already installed, you need to install it. If you do not have a driver disk, this software can be easily found on the Internet.

The uppermost slider is the frequency of the workprocessor. Moving it to the left, you reduce this figure. The second section is the memory frequency of the video card, which is reduced by moving the slider to the left. Select the frequencies you need, then click "Apply".
5
Owners of nVidia graphics cards can take advantage ofprogram RivaTuner. Install the program. Run it. The application window will display the name of your video card. Nearby there is an arrow. Click on it. Then click on the icon on the left. After that, a window will open in which there will be two sliders. The upper slider adjusts the frequency of the processor, the lower one - the frequency of the memory. Moving sliders to the left, you lower the frequencies of the video card. After selecting the desired frequency, click "Apply".
Tip 2: How to find the speed of rotation
Frequency measurement rotation various mechanisms is carried out with the help oftachometers, tachogenerators with voltmeters, frequency meters, stroboscopes and linear speed meters. The first of these devices allows you to get the result directly, the rest - after a simple recalculation of the readings.
You will need
- Speed sensor
- Tachometer
- Frequency Counter
- Tachogenerator with voltmeter
- Stroboscope
- Felt-tip pens
- Linear velocity meter
Instructions
1
Using a tachometer is the most efficient way to measure frequency rotation. It is applicable to mechanisms equipped with frequency sensors rotation or allowing the installation of such sensors. If the sensor is not yet installed, install it when the mechanism is stopped. Connect a compatible tachometer to the sensor. If the sensor requires power, but it does not come from the tachometer, but from a separate source, connect it. Only then start the mechanism and wait until it untwists. On the tachometer indicator, read the result.
2
It happens that the mechanism is equipped with a frequency sensor rotation, but there is no suitable tachometer, but there is a frequency counter. You can make a measurement in this case. Apply external power to the sensor, and instead of the tachometer, connect the frequency counter. Frequency rotation calculate by the following formula: ω = (f * 60) / n, where ω - frequency rotation, rpm, f - frequency meter readings, Hz, n - number of pulses generated by the sensor per revolution.
3
If the mechanism is equipped with a tachogenerator or allows its installation, the frequency rotation measure it like this. If the tachometer is not yet installed, install it when the mechanism is stopped. To the tachogenerator, connect a voltmeter and, if necessary, a source of excitation voltage. Start the mechanism and after the output to the operating mode, measure the voltage generated by the tachometer. Convert it to the frequency rotation, guided by the schedule or the formula from the instruction to the tachogenerator.
4
Frequency measurement rotation strobe is implemented in a non-contact way. At the stopped mechanism put on that its detail, frequency rotation which needs to be measured, with a marking pen. Start the machine and let it spin. Point the strobe to the rotating part, and then adjust the flash frequency control so that the mark appears to be stationary. The scale of the regulator at the strobe usually has a calibration with pulses per minute - in this case, no recalculation is required. If it has a grading in hertz, multiply the reading by 60.
5
The linear speed meter has a rubberroller, which is pressed against the smooth surface of the rotating shaft. Pressing the roller against surfaces that are not smooth, is unacceptable. After measuring the line speed, recalculate it to the frequency rotation by the formula: ω = (v * 60) / (π * (D / 1000)), where ω is the frequency rotation, rpm, v - measured linear speed, m / s, D - shaft diameter, mm
6
If the frequency is measured rotation one link of the mechanism, and it is necessary to find the frequency rotation another link associated with him through the transfer of a particular kind, the recount is carried out, guided by the transfer ratio of this transfer.
7
Frequency rotation Some mechanisms can be found without resorting touse of any additional devices, since all the necessary for this already exists in the device of which the mechanism is a part. So, if the computer fan is connected to the computer's motherboard, determine its frequency rotation You can enter CMOS Setup mode and selectPC Health Status. In a vehicle equipped with a tachometer, you can find out the frequency at any time without any additional devices rotation of the engine crankshaft.
Tip 3: How to reduce the temperature of the video card
Overheating problem Video cards is relevant not only for ownerslaptop, but also for users of a conventional desktop computer. The problem is especially acute in the summer, when the temperature in the room does not allow the cooling system to function normally. It is necessary to remember that increasing the temperature of the video card by 20 degrees from normal reduces the period of its operation by half!
Instructions
1
The easiest way to reduce Temperature video card and processor - to clean the computer fromaccumulated dust. It is necessary to remove the cover of the body and gently sweep the dust with a gentle brush with a long elastic pile. The main places of dust deposition are the fan blades, the fins of the radiator and the bottom of the system unit. After cleaning, it is necessary to remove the dust with a vacuum cleaner. To further protect the system unit, you can install a filter that will not allow dust to enter the enclosure. Cleaning should be done at least once a year. This will allow you to cool the video card by 15-20 degrees.
2
A great way to reduce the temperature of the video cardis to replace the cooler with a more powerful one. In this case, it must meet several parameters - the radiator should preferably be copper, the speed of rotation of the blades is sufficient for cooling, and the noise level is not too high. An important parameter is also the size of the cooler, too large can simply not fit in the system unit or cover several slots. The temperature of the video card after installing a new cooler will drop another 20 degrees.
3
Lowering the temperature by another 10 degrees canDue to the replacement of thermal grease. Thermal grease is a substance with a high thermal conductivity, usually white or gray. When choosing it is necessary to remember that the thermal paste should be resistant to high temperatures, to be incombustible, to have hydrophobic properties and to be safe for health. It must be applied to the cover of the core of the video card. The application on the processor cover will further cool the processor and its internal devices.
Tip 4: How to know the frequency of a video card
Any modern discrete graphics card has its own frequency. Frequency has both a graphics processoradapter, and its memory. The higher these figures, the more powerful your video card. Also, when overclocking the card, it is necessary to rely on the factory settings for the memory frequency and the processor of the card, and starting from this, to deal with its overclocking.
You will need
