4830 modifying BIOS is more energy-saving

Ati's powerplay technology makes it a good thing for us to reduce the power consumption of graphics cards during normal use without compromising performance in the game. Powerplay is mainly implemented through the BIOS of the video card. By modifying the bios, You can optimize the performance of your own video card. Not to mention powerplay, not to mention the purchase of high-end graphics cards is to promote the development of electricity, the game is just entertainment, only a small part of the time, most of the common applications do not need to let the graphics card run too fast, it can save energy, no. If you have any ATI, you can try to modify the BIOS to reduce the frequency and save power. powerplay technology is still very practical. The following uses 4830 as an example to describe how to modify the BIOS. BS: Actually, there are very detailed methods on the Internet. I just read the master's tutorial "Qi Heng 4830 testing, powerplay modification, win7 testing. Baidu searched for the article "Qi Heng 4830 test, powerplay modification, win7 test", where the required software was downloaded. I started with Dilan hengjin 4830,200 9.2.27 690. It seems that the heat dissipation is not very good. The room temperature in Chengdu is about 12 degrees, and the graphics card is usually more than 40 degrees, and the game will reach 69 degrees. Later, I re-applied silicon grease and ran the game about 57 degrees. I heard that the current video card is quite heat-resistant, 100 degrees is okay, but the temperature is certainly good, no. Change to 100/100, the temperature does not drop much, unable to know how the power consumption, anyway, the fan speed is not high, no matter. The following describes how to modify Software required: Atiwinflash 2.0.1.5 the software that fl ati bios in windows. Of course, you can also save the BIOS. Radeon BIOS editor 1.18 Is rbe1.18, which is used to modify ati bios software. This version only supports 4830. First, see the following: First use atiwinflash to save the video card bios and "save ".... Just give a name Open radeon BIOS editor 1.18 and load the previously saved BIOS file. "Load BIOS ...".... Here we can see the BIOS information. Haha, it's nice... But this first thing is not very useful, and dare not change HD 4830 to HD 4870... Click "clock Settings" to change the frequency. Note: Here I load the original version of Dilan hengjin 4830 bios that I saved earlier, that is, it has not been modified. I forgot it. I will not change it. We can see a lot of frequency, GPU, ram, and voltage. How can we tell this? Points have been divided 0th sets of clock info 00 default boot frequency 1st groups of clock info 01 ~ Clock info 03 powerplay settings, 01: 2D frequency; 02: Low 3D frequency; 03: High 3D frequency 2nd clock info 04 ~ Clock info 06 HD video settings, 01: Low video frequency; 02: Medium video frequency; 03: High video frequency 3rd groups of clock info 07 ~ Clock info 09 powerplay settings, 01: 2D frequency; 02: Low 3D frequency; 03: High 3D frequency In fact, if you are interested, you can see the following "powerplay States structure". groups 0, 1, 2, and 3 correspond to the above descriptions. Click here, the software will display each group. The 1st group is the most important. The 3rd group can be the same as the 1st group, or you can simply leave it unchanged. After you understand it, you can set it as needed. My settings are given below Voltage Adjustment may also be very important. I have changed the voltage to 1.044 V in the lowering project. The default frequency voltage does not matter. It turns out to be, it is probably automatic adjustment. Of course, super-frequency graphics cards can also be used here, but do not be too greedy, black screen is not fun. Here, save ..... There is a certain risk that the BIOS will be refreshed below. The power interruption during the refresh process will definitely not work. I am not responsible for this. After loading the file, click "program" (This translation makes me speechless and how to translate it, ah... As you know, you can refresh the BIOS. Note: It takes some time to refresh. The progress bar is very fast at the beginning. However, when it is about 4/5, it will find stuck and the mouse cannot be moved, the numlock press on the keyboard does not respond either. Don't be flustered. Be patient. A dialog box will pop up later, saying "Congratulations!" vbios refreshed successfully. Congratulations. Restart is required. If you look at radeon BIOS editor 1.18, you can adjust the speed of the graphics card fan and change the speed according to the temperature. Dilan's 4830 temperature is not low, and it is useless to increase the fan speed. After several adjustments, I asked the fan to increase to 53% speed at 50 degrees. How can I adjust it, you can do it according to your own situation. For other functions of radeon BIOS editor 1.18, please explore them by yourself. I want to save energy first, ATI graphics card first !!!!!
