As the screens displayed in large games are becoming more and more fine, various graphics card overclocking winds are continuously swept across netizens. Although some graphics cards do not limit the user to perform the graphics overclocking operation, if the graphics card overclocking is limited, users need to flash mobile phones to flash the phone. Like BIOS for the motherboard, brush the graphics card BIOS to break the restrictions. Just as the NVIDIA graphics card swipes BIOS, it is not possible to take a moment. If the user is preparing to refresh the graphics card BIOS, please read the following carefully.

What is the use of graphics card brush BIOS?

1. In fact, under normal circumstances, the BIOS of the graphics card is refreshed for overclocking or opening. In another case, the graphics card brush BIOS is to solve the defects of internal hardware design.

2. The graphics card brush BIOS can crack the flow processor shielded by the graphics card, so that it can improve the performance of the graphics card. Of course, it may be only a part of the model.

3. It can also crack the voltage of the graphics card and change its frequency, so that long -term overclocking can be achieved.

4. It can reduce its own temperature, which is only a limited version of BIOS.

5. Can repair the graphics card bug, such as flower screen, errors in some large games and other situations.

Preparation before refreshing

Before starting to refresh the graphics card BIOS, we still have a lot of preparations to do.

1. Determine the model of the graphics card

At present, the graphics card brand is lined with many models. Different brands of graphics card BIOS is different and generally cannot be universal. The graphics card of the same brand, if different display chips (GPUs) are used, BIOS is different. Even if the products with the same display chip are used with different specifications of memory, its BIOS is different. Therefore, when you refresh the graphics card BIOS, you must "get a seat". If it is brushed into inappropriate BIOS files, it will make the graphics card work abnormal, and the graphics card will be scrapped.

To determine the specific model of the current graphics card, the easiest way is to view the packaging box and instructions attached to the graphics card. In addition, there is generally a model sticker on the PCB board of the graphics card. You can also know the brand and model of the graphics card through it.

2. Determine the BIOS version of the current graphics card

How do I know that the BIOS launched by the manufacturer is new than the current BIOS version? The most commonly used method is to check the driver of the graphics card. In addition, you can also understand the detailed information of the graphics card BIOS through the Evereest software.

3. Download the new version of BIOS file

Find the new version of the BIOS file on the official website of the manufacturer and download it to the hard disk. It should be noted that the download files provided on the Internet are generally compressed files. You need to decompress with decompression software such as winrar. Pay attention to the decompressive file. The file named .exe is a refresh tool (Nvidia special refreshment refresh The program is nvflash.exe, and the special refresh program of ATI is flashrom.exe). Files such as "xxxxx.rom" and "xxxxx.bin" are new BIOS files.

4. Make the DOS startup disk, ready to refresh the file

Because the BIOS refresh work is more reliable in the pure DOS state, you need to make a DOS startup disk. Through the startup disk, the system can guide the system to enter the pure DOS environment. After making the DOS startup disk, copy the downloaded BIOS refresh program and the upgrade file to the same directory of the hard disk. For example, create a new folder called "BIOS" in the C drive, and copy all the files downloaded to the folder.

The preparation work is ready, and then we will start the actual combat stage of the BIOS upgrade of the graphics card.

How to refresh NVIDIA graphics card BIOS

1. Confirm whether the ROM chip supports refresh

Enter the pure DOS environment by starting the disk, and enter "NVFLASH -C" after the command prompt to test the ROM type used by the graphics card BIOS. If the ROM chip supports the graphics card is refreshed, the detailed information of the chip will be listed (Figure 1), and an error prompt appears.

When nvflash and various command parameters are used, they can achieve different functions:

-F: Write the BIOS file named "FILENAME" into the ROM chip of the graphics card, and then check

-b: Read BIOS from the ROM chip of the graphics card, and save it as "FILENAME"

-k: Read BIOS from the ROM chip of the graphics card, and compare it with the BIOS file called "Filename"

-C: Detect the graphics card ROM chip to support refresh

-H: Restart the machine after the BIOS upgrade is completed

-?: Detailed instructions for getting a refresh program, including command line parameters, supported ROM chips, etc.

2. Back up the current BIOS

The parameter of the backup BIOS is "B", and its command format is "NVFLASH -B", that is, the backup graphics card BIOS, which is also stored as "Filename" file. In addition, the work of backup BIOS can be completed in Windows in advance, that is, backup through the NVIDIA BIOS Editor software.

3. Refresh the BIOS process

After completing the backup job, enter "NVFLASH -F" to write the new BIOS into the ROM chip. During the refresh process, the screen will shake and turn black, which lasts about 10 seconds. If you return to the DOS interface again, the refresh is successful (as shown in Figure 2).

The author reminds that the graphics card refreshes the BIOS process and must not be powered off or interrupted, so as not to swipe the BIOS failure.
