System tutorial to modify the graphics card driver installation information

Sometimes when we install a graphics card, some graphics cards can't find the best performance for the best performance. Are you still waiting for this situation? In fact, we can make an empathy, as long as you manually modify the installation information of the graphics card driver, these problems will be solved.
NVIDIA graphics card NVIDIA often has a new version of the driver when it releases a new model card. This version of the driver is higher than the official version of the WHQL-certified driver. The package date is newer and often provides a recent game. Better support and optimization. Unfortunately, these "proprietary drivers" support fewer models of graphics cards. For example, the V267.59 version in the middle of last month only supports GTS 450 and GTX 550Ti graphics cards, while the V267.91 version is the GTX 590 dedicated driver. Other models of N card users cannot use these drivers. On the other hand, the official version of the driver that supports the full range of N cards is usually slower to update, and players will encounter the embarrassing situation of broken files from time to time. It is unfortunate that the driver for the new game has been introduced, but it cannot be installed because it is a dedicated driver for the new graphics card. However, the official does not add the old graphics card model to the "proprietary driver" support list, does not mean that the old model graphics card can not use these new drivers. In fact, we know that official graphics driver updates are usually added, modified and optimized on the basis of the old version. In theory, the support of the old graphics card will not be removed in the new version. The so-called "proprietary driver" is nothing more than the official modification of the installation information, resulting in the driver installation program can not identify other models of graphics cards, if we modify, the original installation information will be restored, "dedicated driver" can still be installed in the full On the series of graphics cards. Below we take the modification of V267.59 version of GTX 550Ti as an example to introduce the modification of N card & exclusive; Download the decompression driver to enter the NVIDIA official website. On the driver download page, select the type of video card, product series and specific model, and then select the system version (system name, number of digits) that suits your computer. The same version of the driver. After downloading the file, it will be decompressed (the path will remain the default), and then it will be installed automatically. If your graphics card is not GTX 550 Ti or GTS 450, it will not be installed. But don't worry, we can modify the inf file to let the 267.59 driver support our graphics card. Need to refer to and modify the inf file ——“NV_DISP” are in the driver installation package to the path just decompressed (default is C:\\NVIDIA\\DisplayDriver), in general, in addition to the 267.59 folder and the previous driver The file (because we modify the 267.59 driver inf also need the old driver inf for reference, if you can not find the old driver installation package, re-download one and extract to this path). I have 266.58 version here, and other versions are the same. Find the graphics card ID. Before modifying, open the GPU-Z detection software. You can find the information of our graphics card in the Device ID of the main interface. The graphics card in the hand is GTX 460, and the Device ID displayed in GPU-Z is “10DE-0E22”, only need to know the following “0E22”. View the device ID of the graphics card in GPU-Z. Modify the NV_DISP file to open the 266.58 folder, locate the Display.Driver folder (C:\\NVIDIA\\DisplayDriver\\266.58\\Vista 64-bit\\International\\Display.Driver), open it with Notepad. The file type is the “NV_DISP” file of the installation file, and the device ID just found is searched. The author searches for the number of GTX 460 < 0E22”, and finds the corresponding three lines, which appear in [NVIDIA_SetA_Devices.NTamd64.6.0], [NVIDIA_SetA_Devices.NTamd64.6.1], and [Strings] (the location of each model card is different). At this time, we will enter the 267.59 driver folder, open the “NV_DISP” installation file, and add the three lines of information that have just been searched for the Device ID to the corresponding location. After modifying the 267.59 driver's "NV_DISP" file, run setup.exe outside the Display.Driver folder, the driver can already recognize our graphics card and install the driver. After the driver installation is complete, our graphics card can experience the performance gains of the new driver. AMD graphics card Since the introduction of the Radeon HD4000 series of graphics cards, AMD's graphics driver has gradually increased, maintaining the frequency of monthly updates, generally optimized for the game, fix BUG, ​​improve performance. Unlike NVIDIA, AMD's graphics drivers are supported in a full range of products, and there are very few dedicated drivers that can only be installed on some models. Of course, sometimes the new graphics card is launched faster, and the related driver updates are not timely. For example, the recent driver version of the new graphics card HD 6790 is only a preview version of the driver catalyst. At this time, we can install the stable catalyst 11.3 driver by adding the installation information. On the new graphics card. Download the decompressed driver and download the N card driver similarly, select the corresponding driver version and system type, and then run the downloaded AMD graphics driver package, here take Catalyst 11.3 as an example. After downloading, start decompressing. Unzip to AMD or ATI folder of C drive by default. After decompressing, you must cancel the installation process first, and then find the folder that has just been driven and decompressed. The INF folder defaults to "C:\\ATI\\Support\\driver version\\Packages\\Drivers\\Display\\”, the W7_INF and W76A_INF folders correspond to 32-bit or 64-bit WIN7/VISTA systems respectively, and the WIN XP system is similar. . Adding the installation information of the graphics card The system used by the author is 64-bit Win7, so you can enter the W76A_INF folder, you can see that there are two files with the file type as the installation information, where <;C7” begins with the corresponding WIN7 system, “CH” Corresponds to the Vista system. The XP system driver has only one installation information. Enter the installation information file at the beginning of "C7", which can be opened with Notepad. It seems that the information inside is very complicated. Actually, we do not need to modify it. The 11.3 version of the driver lacks the information of the HD 6790 graphics card, but the information of the HD 6800 series is still available. We can directly search for the location that needs to be modified by searching for “6800””. Since the HD 6700 series is reduced by the HD 6800 series, the installation information is not much different (of course, you need to know the device ID of the graphics card before the modification, the method is the same as before, or you can also search on the Internet) to add the installation of HD 6790. For example, copy the HD 6800 information “AMD Radeon HD 6800 Series" = ati2mtag_NI, PCI\\VEN_1002&DEV_6738” to the above line, and change “6800 to 6700& rdquo;,” DEV_6738” to “DM_673E” This has successfully added the installation information of the HD 6790. After the modification, enter the installation folder of the 11.3 driver "C:\\ATI\\Support\\11-3…”, double-click "Setup" to install the driver normally, and enjoy the stable and efficient official version of the catalyst driver. Are you still worried about this problem? Then come to the system and have a look at the tutorial! The system will provide you with a better and more professional free learning platform, so that everyone can become a computer master.
