How to use BIOS for mining graphics card

1. Use the radonbioseditor to brush. It can improve the core voltage, core frequency, video memory frequency and so on. However, the brush may be unstable, in case of bad brush may create brick card. Do not pursue the ultimate performance of the general or do not brush the 3850 is still good

2. Upgrade instance
graphics BIOS
below with & quot; Rivatnt & quot; As an example, this paper describes the detailed steps of BIOS upgrade of display card. This display card BIOS chip detail block display card uses 16MB SDRAM, and is a public version of the standard design. The standard BIOS designed by NVIDIA is 2.04.18 and the file name is & quot; tnt18sd.rom" BIOS refresh software is nv4flash.exe version 1.2. First, type nv4flash enter in DOS to get the following prompt:
nv4 flash ROM programming utility. V1.2
the monitor attached to the nv4 may Flickr
as the prom pins are enabled and disabled
example of use: nv4flash full.rom
nv4flash full.rom read and programs flash ROM to full.rom
nv4flash E software erase
picture card BIOS picture card biosnv4flash D mp ROM
nv4flash C check for supported EEPROM
nv4flash w write protect
nv4flash r reset write protect
nv4flash? Display options use & quot; NV4FLASH C" To test the ROM used by the BIOS of the display card. The results are as follows:
(C2 AA)
MXIC 12.0V mx28f1000p flash EPROM
this shows that this video card uses flash EPROM and should be able to be refreshed by software. And then it started to upgrade! Enter nv4flash tnt18sd.rom< At this time, the screen appears chaos and high-speed jitter, but this is normal. After a few seconds, the screen display returned to normal and got the following prompt: (C2 AA)
MXIC 12.0V mx28f1000p flash EPROM
Writing flash with file - & gt; tnt18sg.rom
Starting address -> 0000
Last address written -> 008fff
this indicates that TNT has been successfully refreshed. Then enter Windows 98 and check the properties of the display card. You can see that the BIOS version of the display card is upgraded to 2.04.18
note: the BIOS of different chips can't be universal, and the BIOS of different brands of the same chip can't be universal.

3. After the BIOS fails to refresh, it can be turned on, that is, there is no display, that is, the display is black. In this case, it is very difficult to operate in the dark, which is unimaginable for people who are used to windows graphical interface. So we have to find another way. First create a boot disk on other computers, and then the refresh program (public version is recommended) and the BIOS data file to the boot disk. You've finished half of it. The next half is the key to repaint. Have a good look! Create an automatic batch file named autoexec.bat with or edit in the boot disk directory, and then enter the name of the refresher file plus space and the name of the refresher file. After saving the file, use the disk to boot the computer with the problem of the graphics card BIOS. When the floppy drive light is not on, press enter a few times, wait more than ten seconds, restart the computer, and you can see the boot self-test picture that you haven't seen for a long time
see here, you basically understand! However, if your computer is booted directly from the hard disk, just listen to me. When starting up, press F8 wildly and enter the Windows startup menu after about 20 seconds. Type the number & quot; 6" After that, enter the BIOS state and type & quot; a:\ autoexec", You can also refresh the graphics card BIOS.

4. The BIOS software of a card is techpowerup radon BIOS editor.

the BIOS software of N card is nibitor.
all of them are operated, modified and refreshed under the system.
if you want to have a BIOS file that you want to swipe in, just use the corresponding software to load and swipe in and restart it directly. (the premise is that the BIOS must conform to your graphics card model, including parameter frequency, etc, You can also modify the corresponding parameters directly in it. However, novices suggest to find the corresponding BIOS brush. If you can't modify the parameters yourself, it will become a brick

5. Required software:
1. Imager's grinding disc (I believe it's not strange, especially for players of imager's graphics card, they can also perfectly support other brands of graphics card)
2. Nibitor (editing software for BIOS of graphics card)
3. Gpu-z
4. Some ing software, 3DMark06, and the next point of game, such as island crisis, biochemical crisis, are used to test ing after overclocking
Start:
1. First, use the imager disc to soft overclocking the graphics card, and the amplitude should not be too large; After the application, repeatedly run 3dmark 06 or play an island crisis for 1 or 2 hours, ring which there is no splash screen or crash phenomenon, indicating that your overclocking is successful and stable. Write down the frequency of overclocking data, core, video memory and shader
2. Open gpu-z, backup and save the BIOS of the graphics card
3. Open nibitor software to edit the frequency of the original BIOS, as long as the data of soft overclocking is rewritten and saved separately. The order is core - shader - video memory
4. Then click magic BIOS and select the BIOS you edited with nibitor to swipe in. After a few seconds, it will be displayed that you have finished restarting the computer
5. Enter the system again and use GPU to check whether the default frequency of the graphics card is the modified data

6. First of all, there is a risk in brushing the BIOS of the graphics card. Please prepare the bright card or the check / collective display output so that it can be recovered when you brush the BIOS black.
secondly, you need to know what the purpose of brushing the BIOS is and don't play with it idly.
note:
1. Generally, the BIOS of the graphics card is stable enough, There is no special case, you don't need to brush frequently
2. The purpose of brushing the BIOS of the graphics card is usually to turn on the core or overclocking. For example, 6950 swiping into 6970 BIOS may turn on the shielded SP, while public graphics card swiping into non-public high frequency BIOS can achieve the effect of overclocking once and for all.
3. Generally, graphics cards with the same layout pcb can swipe into each other's BIOS, but generally, it is recommended that players without certain DIY ability first ask in the forum to confirm that their own model of graphics card can be swiped into the corresponding model of BIOS.

7. 1. Determine the model of graphics card

at present, there are many brands and models of graphics card in the market. Different brands of graphics BIOS is not the same, generally can not be universal. The same brand of graphics card, if using different display chip (GPU), BIOS is not the same. Even if the procts with the same display chip are matched with different specifications of video memory, their BIOS is not the same. Therefore, when refreshing the BIOS of the graphics card, you must "take your seat according to the number". If an inappropriate BIOS file is swiped in, the graphics card will not work normally, or it will be scrapped

to determine the specific model of the current graphics card, the simplest way is to check the packaging box and instructions attached to the graphics card. In addition, there is usually a model sticker on the PCB of the graphics card, through which you can know the brand and model of the graphics card< Determine the BIOS version of the current graphics card

how to know that the BIOS version of the manufacturer is newer than the current BIOS version? The most common method is to check the driver of the graphics card to understand the BIOS version information of the current graphics card. In addition, through Everest this software can also understand the details of the graphics card BIOS

3. Download the new version of BIOS file

find the new version of BIOS file on the manufacturer's website and download it to the hard disk. It should be noted that the download files provided on the Internet are generally compressed files, which need to be decompressed by WinRAR and other decompression software. Pay attention to the decompressed files. The files with suffix. Exe are refresh tools (NVIDIA's special refresh program is nvflash.exe, ATI's special refresh program is flashrom.exe), Files such as "XXXXX. ROM" and "XXXXX. Bin" are new BIOS files

4. Make DOS boot disk and prepare to refresh files

because BIOS refresh is more reliable in pure DOS state, you need to make a DOS boot disk, through which you can guide the system into pure DOS environment. After the DOS boot disk is made, the downloaded BIOS refresh program and upgrade file should be copied to the same directory of the hard disk. For example, create a new folder named "BIOS" on Disk C, and all the downloaded files to the folder. If it is found that there is no refresh tool attached to the download file provided by the manufacturer, the special refresh tool for the graphics card must be downloaded from websites such as "driver's home"

all the preparations are ready. Next, we are going to enter the actual stage of upgrading the BIOS of the graphics card< How to refresh the BIOS of NVIDIA graphics card

1. Confirm whether the ROM chip supports refreshing

enter the pure DOS environment through the boot disk, and input "nvflash - C" at the command prompt to test the ROM type used by the BIOS of the graphics card. If the refresh program supports the ROM chip of the graphics card, the detailed information of the chip will be listed (as shown in Figure 1). Otherwise, an error will appear

a Meng tip: nvflash can achieve different functions when used with various command parameters:

- F: write the BIOS file named "file name" into the ROM chip of the graphics card, and then verify it

- B: read the BIOS from the ROM chip of the graphics card, and save it with the name of "file name"

- K: read the BIOS from the ROM chip of the graphics card, Compared with the BIOS file named "file name"

- C: check whether the ROM chip of the graphics card supports refresh

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

-?: Get the detailed description of the 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 CB", that is, back up the BIOS of the graphics card and coexist as a "file name" file. In addition, the work of backing up BIOS can be done in advance under windows, that is, through NVIDIA BIOS editor

3. Refresh BIOS process

after completing the backup work, input "nvflash CF" to write the new BIOS to the ROM chip. During the refresh process, the screen will shake and turn black, lasting about 10 seconds. If you go back to the DOS interface again, the refresh is successful (as shown in Figure 2)

it should be noted that the refresh process must not be powered off or interrupted to avoid the refresh failure.
