How to use RivaTuner, RivaTuner tutorial

RivaTuner's superiority is that you can make various settings for the graphics card from the hardware layer and the driver layer respectively. The driver layer setting is to set the graphics card through various API functions and driver registry key values. It is characterized by a richer tuning option than the driver control panel, and the application can be configured separately to avoid unnecessary troubles caused by global setup errors. There are relatively few hardware layer setting options. It directly accesses the underlying hardware through a high-level programming language, so it has certain versatility, providing perfect support for A and N cards, clock frequency generators, registers, logic circuits, etc. The direct operation access also guarantees the accuracy of the acquired data, but the characteristics are dangerous, and the user needs to have some understanding of the hardware. Let's start with the hardware layer setup:

Click the System Settings button to enter the Hardware Layer Frequency System Settings window: The first time you enter the settings, a window will pop up, letting you determine that it is "Re Start & rdquo;, “ Immediate Detection & rdquo; or & ldquo; Abandon & rdquo;, the first time it is strongly recommended to restart the resulting clock frequency will be more accurate. On the surface, the setting of this window is no different from the RC14 version, but there are still many changes. Firstly, the time when the first startup is started is “free restart detection clock frequency”, and the clock frequency is increased. The accuracy of the test, and in order to prevent the start of the crash when the frequency setting exceeds the range of the graphics card, the new version absorbs the clock frequency test technology in the Forceware driver control panel. For GeForceFX series boards, when setting When the value exceeds the tolerance of the graphics card, except for the yellow warning number on the left core and the memory icon, after the point test, there is no longer a long detection progress bar like the RC14 version, and the system will determine in a short time. Whether the frequency you set is beyond the tolerance of the graphics card, there will be no more screens and crashes caused by improper settings. At the same time, it should be explained to everyone that for different grades of graphics cards, the situation here is different, for example, for GeForceFX series boards, because the 2D and 3D clock frequencies are separated, in order to avoid conflict with the driver layer frequency setting. The overclocking setting here is not available, and the “recovery frequency setting after sleep wakeup” is also available only when the detonator and the early Forceware driver are installed. Anyone with any questions can be used to get the answer. Click “More” to enter the sub-option window related to the frequency setting: Related knowledge: The PLL circuit is also called the frequency generator. The graphics card uses the PLL chip and its nearby 14.3MHz crystal oscillator to generate different clock signals. In order to provide different crystal frequency to the core of the graphics card and the memory, a plurality of crystal oscillators can be outputted according to various combinations in the PLL circuit to determine the clock frequency of the hardware operation or the step value when the frequency is adjusted. There are five options in the Clock Frequency Accuracy drop-down box: Custom, Low Accuracy (Safest), Normal Accuracy (Driver Frequency Adjustment), High Accuracy (Small Safety Factor), Maximum Accuracy Degree (minimum safety factor), generally selected here, the following core and memory frequency options will automatically apply or cancel some options, because these options directly control the working state of the frequency generator and crystal oscillator, therefore Ordinary users only need to choose one of the four recommended modes. Only users who are very clear about these options are recommended to make a custom selection. Go back to the main interface of the system settings and click the “AGP” label above to enter AGP. Setup Page: Tip: Sideband Addressing: It refers to a separate address and instruction bus. When the AGP 2x standard was introduced, the address bus was separated from the data bus. In theory, eight additional sideband lines were added to the AGP bus. It allows the graphics control chip to send new AGP data requests and transfer instructions to the system memory in parallel without disturbing other data continuously through the main 32-bit address data transmission line of the AGP bus, thereby transmitting the AGP bus transmission efficiency and throughput. The amount is played to the extreme. AGP Fast Write: The fast write feature itself is part of the AGP 2.0 specification. It allows the CPU to pass data directly to the graphics processor's memory unit without having to go through system memory, thereby reducing data transfer time and increasing the efficiency of 3D applications. For the latest graphics cards, the above options do not need to be set. These settings are mainly for those early motherboards and graphics cards. For example, the motherboard BIOS does not provide support for two options or the graphics card works in a certain state. When stable, you can force it to be turned on or off with the above options for better performance or compatibility. Graphics cards based on the AGP 3.0 standard are not available in gray. Click on the third tab item <;NVStrap driver” to enter the NVStrap driver settings page.

The hardware layer essence setting section is here. It is necessary to explain the DeviceID first. For each graphics processing core, there is a unique ID number for distinguishing other models. It determines that the graphics card is 5200. 5600, 5800 or Quadro550, Quadro1100. As far as the current situation is concerned, we can basically prove that there is no difference between the graphics professional card and the home-level graphics card. The biggest difference is that the graphics card is equipped with a specially optimized driver. Therefore, since the TNT era, the cracking of home-grade graphics cards into professional cards has become a tireless pursuit of generations of DIY players. The meaning of the NVStrap Driver literal can be translated as a bound NV graphics driver. It is a very small program. After installation, it is embedded inside the operating system and is loaded before the driver to replace the driver driver between the hardware and the driver. Dialogue, it first spoofs the ID number of the graphics card to the system as the ID number of the Quadro card, thus loading the driver of the professional card, and releasing all the feature settings of the professional card, forcing the OpenGL ICD (interface control file) to be specifically targeted Professional cards are optimized for the graphics API to achieve comparable performance to professional cards.

Click to enter the refresh rate setting:

The first option is quite useful for the refresh rate lock setting. Friends who often play games under Windows2K/WindowsXP have had this experience. For example, the refresh rate you set in the desktop state is obviously 85MHz, but when you enter the game, such as CS or Quake3, the game screen will become flickering. It will be unbearable to play for a long time. Here we can give you a perfect solution. Click the "Add Locked Standard" button to enter the refresh rate lock settings page: Please don't be confused by so many setting options, as shown in the figure: as long as you set the desktop resolution at 640 * 480 * In the range of -1024*768, the color quality is between 16-32 bits. Regardless of whether you set the refresh rate to any value between 60-200, RivaTuner will force the refresh rate to 85, which can be avoided. The 60MHz problem under the game can also avoid accidentally setting the refresh rate too high beyond the range that the display can withstand. Need to be reminded here, if you choose "Maximum resolution supported by the display driver", be sure to ensure that the display is not recognized as "Plug and Play display", "Default monitor" or "Unable to use" The identified monitor & rdquo; otherwise the maximum refresh rate given may be too small or beyond the range that the display can withstand. As for the lock mode on the main interface, it is mainly because the lock mode requires RivaTuner to reside in the memory, which will cause some compatibility problems with the system settings, so you can select “<quo;performance mode","mix mode" , < compatibility mode& quo; to achieve the best performance and compatibility. “Display Driver Setup Wizard” Allows you to generate an INF installation file from the display's EDID or from the installed driver to extract the driver information. This is relatively simple, so I won't go into details. Continue to click the button to enter the desktop color settings window: The changes here are also quite large, the most obvious is the addition of "Direct access to RAMDAC palette" control mode and "Custom color curv" adjustment mode. “Direct access to RAMDAC palette& quoquo; It allows the program to directly access the color register of the RAMDAC to achieve color settings. The disadvantage of GDI mode is that it is not allowed to set all possible gamma ramp values, it will check the gamma ramp, and if it is too complicated, it will refuse to execute. The latter's adjustment range for gamma ramp is more free and flexible than GDI mode, allowing the user to set a single color, which is not available in GDI mode. And can support both A and N cards. In addition, another change is to add a similar color curve adjustment method similar to the Forceware driver control panel, allowing you to drag the color curve to customize the settings, providing more flexibility than changing the color settings with the slider. Degree of freedom. Click the button to enter the graphics subsystem diagnostic window. Here is the detailed information of the system board and graphics card project. In addition to the detailed information of the system, you can also see if your graphics card is working properly. Click the button to enter the hardware monitoring window: Compared to the old version, hardware monitoring provides more monitoring options, such as core and ambient temperature monitoring options for NV3X series, 5700U, 6800 series, ATI 9600XT, X800, etc. for NV30 The /NV35/NV38 series of graphics cards add core voltage monitoring options and allow you to instantly minimize the display of a single monitoring data on the taskbar. For example, after overclocking the core of the graphics card, you are worried that the core temperature of the graphics card is too high, and you can display the real-time change data of the core temperature in the taskbar by setting it, so that the working status of the graphics card is well understood.
