Hello everyone, Lin Fei to answer the above questions, integrated graphics card overclocking how to solve the black screen, integrated graphics card overclocking many people do not know, now let's take a look!

When it comes to computers, we all know its core components, and the graphics card is one of them. Video cards include integrated video cards and independent video cards. Integrated video card refers to the combination of integrated video card, sound card and network card on the integrated motherboard. Compared with independent display, integrated graphics card is not as popular as independent display, but as a result, the price of integrated graphics card is much lower and the installation is more convenient, but the disadvantage is worse performance. To solve this problem, Bian Shaw today recommends some ways to improve the performance of integrated graphics cards, mainly through setup and optimization.

1. Optimize BIOS settings to improve display performance

Performance is the most important bottle diameter for the performance of the integrated motherboard, especially when running 3D games and other programs that test the performance of the graphics card, the integrated graphics card will expose its own shortcomings. The BIOS setting is closely related to the performance of the integrated graphics card. Note and adjust the following BlOS options to bring higher performance and stability to the integrated graphics card.

1.AGP date recitation

For the general motherboard, the higher the AGP rate of the graphics card, the better, but not necessarily for the integrated graphics card, because the current integrated graphics card only uses the AGP channel to transmit a small amount of instruction data, and the graphics data that really eat bandwidth has gone to the special channel of "display core-memory". Therefore, the AGP rate will not become the performance bottleneck of the integrated graphics card, but too high AGP rate will bring unstable factors to the system. Therefore, it is recommended that you also keep the default value.

2.AGP, write.

Fast writing means fast writing. This option can improve the performance of the integrated graphics card, but it may also have a negative impact on the stability of the system. As a rule of thumb, only newer integrated graphics cards such as nForce2 1GP, n9100, and 661FX can use the fast write option properly.

3. Graphics window WR combine harvester

This option is more common in integrated motherboards based on SiS chipsets. It can optimize the reading and writing performance of the graphics system and improve the performance of the integrated graphics card. It is recommended that you turn on this option.

4. Video BIOS cacheable

Its purpose is to determine whether to reference VGA BIOS and RAM buffers to an address field in memory. Although it can improve the performance of some integrated graphics cards when turned on, once a program writes data to this address field, the computer will crash. Therefore, it is recommended to turn off this option, because video BIOS Cachable can only improve the performance of the integrated graphics card, but bring instability to the computer.

5.AGP aperture size

The AGP aperture size option represents the size of the AGP effective space, that is, the amount of memory allocated to video memory. How to allocate memory capacity has always been a difficult problem for integrated motherboard users. If you increase the memory capacity, the memory capacity will be reduced, affecting the overall performance. If the memory capacity is reduced, it will also affect the performance of the video card. Through practical use, the AGP aperture size option has no significant difference in the performance of 32MB memory and 64MB memory. In fact, 32MB video memory can meet the needs of most new integrated graphics cards, while three-year integrated graphics cards like sis630 only need 16MB video memory.

Intel chipset integrated graphics card has its own video memory allocation method. In the early days, Intel's integrated graphics cards did not require manual adjustment of memory capacity, but were automatically allocated. Later, Intel added a "hierarchical memory" function to Intel Supreme graphics card and its follow-up products. The so-called hierarchical memory is "rated memory dynamic memory". Rated memory specifies the minimum allocation value for video memory. When the minimum allocation value is insufficient, the operating system will be asked for more memory to be classified as video memory (dynamic video memory). Therefore, if you do not play large games, you can set the rated video memory a little smaller (such as 1MB), which can not only meet the needs of the game, but also save a lot of memory. On the contrary, it is best to set the rated video memory above 8MB, which will waste some memory, but will get better game compatibility.

In addition, the size of the memory allocation is closely related to the memory size (except for integrated motherboards such as the Intel 81x). If your memory is 1.28 MB, that is

Many players have tried independent graphics card overclocking, integrated graphics card can also overclocking to improve performance. Integrated graphics card overclocking does not need to set any soft and hard jumpers, only need to modify the Windows registry or use special software overclocking graphics card. Because modifying the registry requires some professional knowledge, and more troublesome, and the graphics card overclocking software is easy to use, the effect is also good, so it is the player's first choice.

PowerStrip is a universal overclocking software for graphics cards. When you run PowerStrip after installation, a dialog box appears showing the model of the video card and monitor, defining whether the refresh rate is set according to the standard or custom settings, and whether to run DDC to check the plug and play monitor at startup. Then click the OK button, the power board will reside in memory, and the work icon will be displayed on the taskbar. Right-click the icon, which will pop up the list of main jobs for PowerStrip, and then select performance profile-configuration. The software will pop up a dialog box based on the type of video card chip you are using, and the display chip type of the video card will be marked at the top. The box under "engine clock" is the core working frequency of the current video card, and the box under "memory clock" is the working frequency of the current video memory. If you want to overclock the video card

In addition, for some integrated motherboards, BIOS can be used to adjust the frequency of the display core, which is more simple and convenient.

Third, the reasonable setting of integrated sound card

Compared with the graphics card, the sound card takes up much less system resources, but some system resources will still be saved through reasonable setting. For example, turning off the StoreWide or 3D Depth options in the "volume control" in the Windows environment will greatly reduce the CPU occupancy of the sound card. Generally, the default value of Windows is on.

If you have high requirements for sound quality. Using the audio cable of an ordinary sound card may not necessarily meet your requirements, when listening to CD or VCD, you can directly connect the speaker to the headphone Jack of the optical drive, because this is a digital output effect, which is much better than using the original analog signal output and has less distortion.

If you don't like to listen to CD, it is recommended that you turn off both MIC and CD in the sound properties, which can greatly avoid all kinds of noise. The solution is to double-click the trumpet icon in the system taskbar, and then mute CD-ROM and MIC PHONE.

As for the specific bass and treble settings, the ideal solution is to adjust the bass slider of your sound card to 60% and the treble to 80% in the sound properties, and the total system volume should be about 85%. Of course, you can also choose the value according to your personal taste.

For the motherboards of nForce2 and SIS 655 chipsets with ALC650 AC97 sound effect chip, it is easy to produce burst sound when playing audio files. This is because there are some problems with its hardware acceleration support for DirectSound. Just run the DirectX diagnostic tool and lower the "hardware sound acceleration level" in the "sound" speed item to reduce the burst level.

Fourth, correctly adjust the CPU main frequency and memory frequency

Both CPU main frequency and memory frequency are important factors that affect the display performance of integrated motherboard, especially its display performance. Now the motherboard has a certain frequency division ratio to non-standard external frequency. In general, memory may have to be reduced when CPU overclocking. So who has more influence on CPU main frequency or memory frequency?

For the integrated motherboard that supports dual-channel DDR memory, the memory bandwidth is sufficient, and the performance bottleneck mainly comes from CPU, so appropriately increasing the CPU frequency will bring higher performance. For those integrated motherboards that only support single-channel DDR memory, their performance bottleneck comes from memory bandwidth, not CPU, so it makes more sense to increase the memory frequency appropriately.

The above methods seem a little complicated, and people who do not understand computers may not understand them, but as long as they have knowledge of computers, or computer enthusiasts and enthusiasts, they can certainly use the above methods to improve the performance of integrated graphics cards. Although integrated graphics cards are not mainstream products, as long as there are integrated graphics cards, someone is bound to use them. If its performance is not good and there is no need to rush to replace a new one immediately, you might as well try the above methods, perhaps the final effect is very good.

At the end of this article, I hope it will be helpful to you.
