Modifying the computing power of graphics card BIOS

1.

The main functions of NVIDIA NVIDIA NVIDIA BIOS Refresh Tool 5.190.0.1 are as follows:

1, refresh BIOS to chip

2, save BIOS (before refreshing the new BIOS, it is better to use this function to back up the old BIOS, so that if there is a problem after refreshing, it can be recovered)

3 Compare the BIOS version of the graphics card (you can compare the BIOS currently in use with the BIOS to be refreshed)

4, upgrade TV data

5, display the BIOS Version (you can display the BIOS version currently in use and the BIOS version to be refreshed)

6, display the number of bytes of BIOS

7, detect whether the BIOS can support refreshing

8 Add write protection to BIOS

note: the ideal operating environment for nvflash is DOS, do not execute it under other operating systems; Moreover, updating BIOS is a risky action. If you don't have certain computer hardware skills, please don't try it easily

2. Desktop generally press Delete, ESC, F2 key, specific with the motherboard manufacturer
in terms of laptops, different laptops have different ways to enter BIOS, which causes many people's troubles when entering BIOS: most laptops press F2, F1 or F12. It's better to check the specific model on the official website
after re installing the machine, you can start up the computer and obviously feel the main fan running at full speed, which is noisy. Enter the BIOS and click the fan interface to view the fan speed
we check the intelligent fan mode and click the auto mode (directly drag the temperature point to set). Set the main fan speed of CPU at 20 ℃, 40 ℃ at 40 ℃, 65% at 60 ℃, and 100% at 70 ℃ and above
after setting, it is obvious that the main fan speed drops to 874 rpm and the chassis fan maintains at 579 rpm. Next, let's set the fan speed of the chassis to keep the temperature of the fan speed, so that it will not be out of control and will stop and rotate. I think it can be increased appropriately to improve the air ct of the chassis
same as CPU main fan setting. When the temperature is 20 ℃, the speed is 20%; When the temperature is 40 ℃, the speed is 40%; At 60 degrees. The rotation speed is 65%; When the temperature is above 70 ℃, the speed is 100%
after setting, the chassis fan speed is maintained at 590prm
the CPU main fan and chassis fan are all set. Normally, the main fan speed is 886prm up and down, and the chassis fan speed is 596prm up and down. If you don't listen carefully, you can't hear the sound
finally, after adjusting the fan speed, the whole computer is much quieter. In normal office, the speed is maintained at 800 ~ 900 rpm. If you don't listen carefully, you can't hear the sound of the fan. In the game or machine, the fan speed reaches the maximum value (1550rpm up and down), the sound is a little noisy, can play a perfect performance Generally speaking, when the fan speed is within 1000 rpm, the sound is very small; When the fan speed is between 1000 and 1500 rpm, the sound is obvious; Fan speed is above 1500rpm, noise can be obviously felt)

3. Different versions of Bois have different options! The common AGP is as follows: AGP mode AGP mode determines the frequency of AGP, which is a multiple of 66MHz, 1 × The slowest, 8 × The fastest. At present, it can really support AGP 8 × Only the xabre of SIS is available. Some motherboards have automatic detection function, which can determine the most suitable speed according to the graphics card in the AGP slot. Some graphics cards may have a "AGP 4" in their advanced properties × Mode "enable / disable setting options, enable will be set to 4 ×， Disable will be set to 2 × The old Intel BX and via Apollo motherboards do not support AGP 4 e to the chipset they use ×， So there is no 4 × Select the highest value for these motherboards. AGP fast writes (AGP fast writes) determines whether the video memory is allowed to be written directly without transferring through the system memory. When this setting is set to "enable", it can rece the time for image data to be transferred to the graphics card for processing, because it skips the system memory controller. Setting this option to "enable" can improve performance at the expense of system stability. Some motherboards do not have this option, but generally speaking, motherboards with overclocking function provide this option. AGP sideband addressing (AGP sideband addressing) allows the graphics card to process more AGP requests without recing the main address / data transmission speed. NVIDIA said that the "enable" setting can improve the performance of the graphics card, but it may also lead to system instability, especially after the external frequency of the system is over frequency. AGP aperture size (AGP aperture size) the specific function of this item is to set the memory size of the AGP card sharing system. There are seven parameters that can be selected: 4MB, 8MB, 16MB, 32MB, 64MB, 128MB and 256MB. The default value is 64MB and the default value is 64MB. It is recommended to select the default value, namely 64M. Special attention: the change of "AGP sideband addressing" may cause system instability. Please modify it carefully!

4. After entering the BIOS, "advanced
chipset
setup" - on board
VGA
share
menu "should be to adjust the video memory
, and the size of the adjustment depends on the size of the memory

5. 1. Power on and press del to enter the main board BIOS
2. Select "advanced" → Northbridge configuration → rs780 configuration → internal graphics configuration → internal graphics mode → there are four options,
respectively:
1. Disabled indicates that the integrated graphics card is not used (if there is no external independent graphics card, set this option to turn off the motherboard, remember)
② UMA means that only shared memory is used as video memory
3) sideport means only on-board video memory is used
④ UMA + sideport means to use the on-board video memory + shared memory as the video memory of the video card
3. Select UMA + sideport (system memory + on-board video memory mode) to open the on-board video memory. The UMA frame buffer size option below is the capacity selection of shared memory. For example, when 512MB is selected, the total video memory capacity is 512M + 128M. After testing, it is found that choosing side port memory + UMA 256MB can improve the performance of AM2 CPU by 15-18%.

6. ATI's drivers are all like this. You should use ghost to do the system. You should try to use XP which is normally installed, and then install the driver. It should be OK. Ghost will integrate some driver resies that have not been eliminated, which is easy to cause driver failure of graphics cards, especially ATI cards

I hope you still find the driver problem and don't think about brushing BIOS. The new version of BIOS can be downloaded in the driver support of the official website, but usually the information of the graphics card is not stored in the BIOS. It's not an integrated graphics card. How can the main board BIOS manage the external independent graphics card

there is also the so-called high-level BIOS that supports new graphics cards. If it doesn't, it won't light up at all. That's not support. Now obviously, the drive is not good.

7. Is your graphics card al BIOS? It's possible that you only brush one and another to take over the work. It's suggested that you remove the other to see the effect (don't brush the other, so that you can replace it in case of any problem)
in addition, the voltage of NVIDIA graphics card behind Kepler core is locked and can't be modified

8. Use the driver to brush the machine.

9. There are two possibilities
1. If you only modify the display name of the graphics card, such as boot display, OEM information, etc., then the driver will still automatically install the 7600gt driver

2. If you change the hardware ID and crack the driver identification, the system will try to install 9600GT driver, but because the driver used by 7600gt and 9600GT is different, the 9600GT driver can't make 7600gt work normally, so the driver can't be installed, or the black screen and blue screen may appear

don't think about good things. 7600gt can't be upgraded to 9600GT. If you just satisfy your vanity, just change it according to my first statement.

10. Do not enter the BIOS settings, plug in the graphics card, boot installation of graphics card driver can be, when you buy graphics card with drive CD. If not, go to the next universal driver or relative model driver on the Internet and install it
