Over frequency setting of AMD graphics card of mining machine

1. Atitool is the simplest overclocking tool. Atitool does not contain driver. Before installing it, you should download and install ATI's official catalyst driver. After the installation is successful, start the desktop icon to see the overclocking interface. Just like Omega driver's overclocking method, select the appropriate frequency and click Set clock. It should be noted that atitools is a third-party tool. It needs to run in the background to work, so it can be minimized after the success of overclocking. Do not turn it off, otherwise it will not work. If consumers feel that it is troublesome to manually overclock after each installation, then we can choose a once and for all overclocking method - Rewriting the BIOS of the graphics card. Here, we need to use two software tools -- biosedit and flashrom. Biosedit is responsible for modifying the BIOS of the graphics card, and the extraction and refresh of the BIOS of the graphics card depends on flashrom. First, we need to extract the original BIOS of the graphics card. In pure DOS mode, enter the folder where the flash ROM is located and enter flash ROM - S 0 old.bin (where old.bin is the name of the original BIOS of the saved graphics card, or you can have a name you remember). Second, restart, enter windows, run biosedit, read out the saved BIOS file old.bin, adjust the frequency of the core and video memory to the frequency you want it to run, and then save it as new.bin. The third step is to enter the pure DOS mode again, enter the folder where the flash ROM is located, input flash ROM - P 0 new.bin, and brush the modified BIOS file back to the graphics card. So far, our transformation work is completed. At this point, the graphics card BIOS brush work will be completed, quickly enter the system to see it
please accept if you are satisfied

2. The main board BIOS does not set the graphics card overclocking option, only the CPU overclocking option, you can overclock the CPU. If you want to overclock your graphics card, you need to install the overclocking software. You can find it by searching on the Internet. The software settings are also very simple, such as the GPU core frequency, the working frequency of the graphics memory, and the control of the graphics card fan
simply set the overclocking to increase the core frequency of GPU by 15% and the working frequency of video memory by 10%. Now, overclocking CPU has become an "old-fashioned" thing. You can see a lot of articles about this on any hardware site. As for the friends who bought the first batch of Celeron 300A, if it doesn't exceed 450MHz, they will be treated as monsters. With the hot sale of 3D accelerated graphics card, overclocking graphics card has become a new target for many people. Because the graphics card and CPU are not the same, so the super graphics card method also has its own characteristics. Generally speaking, all kinds of "soft" methods are used to modify the clock frequency of the graphics card, so that the graphics chip works at a higher frequency, which can naturally improve the performance of the graphics card (great significance for 3D acceleration). What needs to be noted is that at present, there is not enough experience in the aspect of graphics card overclocking, so the risk of overclocking is hard to say. Therefore, I'd like to remind all my friends here (the computer automatically turns off) to pay attention: never be too black hearted and overcharge the graphics card too much. If there is any hardware damage, it's too late to regret. Any CPU and graphics card, more or less always can exceed a little bit, but some more and some less. The overclocking potential of your configuration is not very high, and there will be no interesting effect after overclocking
overclocking is not fun either. It's a good thing to say if you succeed. If you fail, it's light. It's not uncommon for the whole motherboard to burn.

3. First of all, your motherboard's support for overclocking is extremely inadequate, and 4800 + is the core of Brisbane. The overclocking performance of AMD processor in this core is extremely low... The main frequency of 4800 is 2.5, and the guarantee is less than 2.9... It's the same as that of no overclocking

Wattman's job is simple. Open AMD's radon settings app, then click the game tab, then global settings, and finally the global wattman tab. You can see it through the interface shown below

The most prominent feature of wattman and its surrounding real-time graphics are called "histogram", which maps your RX 480 activity level, current core clock frequency, video frequency, temperature and fan speed. In other words, every key measurement needs to be monitored by the graphics card when the frequency is over

the most important thing is, if you see some weird graphics, like a big clock speed down, the mouse over problem will call up the statistical information of the time to be specific. If you want to solve a cooling or performance problem, the chart function in wattman is a big boon. A well thought out turning point for this performance tracking feature is the ability to use it globally or only with specific applications

AMD's configuration file settings for each application allow you to use wattman, while specific games run for up to 20 minutes at a time to improve performance. Select the histogram option for the game you want to analyze, and when you start the game, wattman will start recording

in a good way, the relationship between the analysis of this specific application and wattman's overclocking ability can also be applied to the rest of the game on a per game basis. With the file wattman tool in the specific settings of each game of deep red's radon, you can overclock the RX 480 in a shorter time when you need more horsepower and concave convex target temperature

First of all, you need to make sure that you are a graphics card with better heat dissipation. Other settings remain unchanged by default

1, start amd settings in your program bar, as shown in the figure below

extended data:

1, in the early 1980s, two famous symbols represented the situation of AMD. The first is the so-called & quot; Asparagus age;, It represents the company's determination to increase the number of patented procts it offers to the market. Like this kind of high profit crops, the development of patented procts takes quite a long time, but it will eventually bring satisfactory returns to the initial investment. The second sign is a huge wave. Amd regards it as & quot; Catch up with the trend & quot; It is the core symbol of recruitment activities, and uses this wave to show an irresistible force in the field of integrated circuits

2, we are really unstoppable. AMD's R & D investment has been ahead of other manufacturers in the instry. At the end of fiscal year 1981, the company's sales more than doubled from fiscal year 1979. During this period, amd expanded its plant and proction base, and focused on building new proction facilities in Texas. Amd has built a new proction base in San Antonio and expanded its plant in Austin. Amd has rapidly become an important competitor in the global semiconctor market

1. Use the official "AMD ryzen master" software for overclocking

it is recommended to use the official "AMD ryzen master" special software for overclocking, the method is very simple, we choose a configuration file, we modify the CPU frequency and core voltage, we change the core frequency to 3600 (3.6), and the voltage should be increased appropriately, It is suggested to increase the core frequency test bit by bit

8. The overclocking of computer is to increase the working frequency of CPU, graphics card and other hardware by artificial means, so that they can work stably at a higher frequency than their rated state. Taking the Intel P4C 2.4GHz CPU as an example, its rated working frequency is 2.4GHz. If the working frequency is increased to 2.6GHz, the system can still operate stably, then the overclocking is successful

the main purpose of CPU overclocking is to improve the working frequency of CPU, that is, the main frequency of CPU. The main frequency of CPU is the proct of external frequency and multiple frequency. For example, if the external frequency of a CPU is 100MHz and the frequency multiplier is 8.5, its dominant frequency can be calculated as external frequency × Frequency doubling = 100MHz × 8.5 = 850MHz

the main frequency of CPU can be improved by changing the frequency doubling or external frequency of CPU. But if you are using Intel CPU, you can ignore the frequency doubling, because Intel CPU uses a special manufacturing process to prevent the modification of frequency doubling. AMD CPU can modify frequency doubling, but the improvement of CPU performance is not as good as external frequency

the speed of external frequency is usually closely related to the speed of front-end bus and memory. Therefore, when you improve the CPU external frequency, the performance of CPU, system and memory also improves< There are two main ways of CPU overclocking:

one is hardware setting, the other is software setting. Hardware settings are commonly used, which are divided into jumper settings and BIOS settings<

1. Jumper setting overclocking
most early mainboards used jumper or dip switch setting to overclocking. Near these jumpers and dip switches, some tables are often printed on the motherboard, recording the functions defined by the combination of jumpers and dip switches. In the off state, you can set the frequency according to the table. After rebooting, if the computer starts up normally and runs stably, it means that our overclocking is successful
for example, an Intel 845d chipset motherboard used with Celeron 1.7GHz adopts the mode of jumper overclocking. Below the inctance coil, we can see the description table of jumper. When the jumper is set to 1-2 mode, the external frequency is 100MHz, and when it is changed to 2-3 mode, the external frequency is increased to 133MHz. The default external frequency of Celeron's 1.7GHz is 100MHz. As long as we upgrade the external frequency to 133MHz, the original Celeron's 1.7GHz will work at 2.2GHz, isn't it very simple:)

another via kt266 chipset motherboard used with AMD CPU uses dip switch setting method to set CPU frequency doubling. Most of AMD's frequency doubling is not locked, so it can be modified to carry out overclocking. This is a five group dip switch, which can be combined into more than ten modes through different on-off states of each serial number switch. A description table is printed on the top right of the dip switch to illustrate the changes of different frequencies caused by different combinations of DIP switches

for example, when we overclock an AMD 1800 +, we should first know that the dominant frequency of Athlon XP 1800 + is equal to 133MHz external frequency × 5 times. As long as we increase the frequency doubling to 12.5, the CPU dominant frequency will be 133MHz × 12.5 ≈ 1.6GHz, equivalent to Athlon XP 2000 +. If we increase the frequency doubling to 13.5, the main frequency of CPU will be 1.8GHz, and the over frequency of Athlon XP 1800 + will become Athlon xp2200 +. The simple operation will greatly improve the performance, which is very interesting<

2. BIOS setting overclocking
now mainstream mainboards basically give up jumper setting and dip switch setting mode, change CPU frequency doubling or external frequency, and use more convenient BIOS setting

for example, softmenu III of abit and powerbios of epox belong to the mode of BIOS overclocking. In CPU parameter setting, you can set the frequency doubling and external frequency of CPU. If the computer can't start normally after overclocking, just shut down and press ins or home key, restart, the computer will automatically return to the default working state of CPU, so it's better to overclock in BIOS

here, the combination of nf7 motherboard and Athlon XP 1800 + CPU is used to realize the overclocking. At present, there are two main brands of BIOS in the market, one is phoenix award BIOS, the other is AMI BIOS, here is award BIOS as an example

first start the computer and press del to enter the BIOS setting interface of the motherboard. Select soft menu III setup from BIOS, which is the softmenu overclocking function of upgrade motherboard

after entering this function, we can see that the system automatically identifies the CPU as 1800 +. We need to enter here to change the default recognized model to user define mode. After setting to manual mode, the original gray non optional CPU external frequency and frequency doubling are now in the optional state

if you need to use the enhanced external frequency to overclock, enter here at external clock: 133MHz. There are many external frequencies to adjust. You can adjust it to 150MHz or higher. Because the increase of external frequency will increase the frequency of system bus and affect the stability of other devices, the method of locking PCI frequency must be adopted

multiplier factor is the place to adjust the frequency doubling of CPU. After entering the options area, you can select the frequency doubling according to the actual situation of CPU, such as 12.5, 13.5 or higher

rookie: if the system can't start normally or work unsteadily after CPU overclocking, I heard that it can be solved by increasing the core voltage of CPU. Is that reasonable< A Meng: Yes. Because CPU overclocking, power consumption will increase. If the supply current remains unchanged, some CPUs will not work normally and stably e to insufficient power consumption. After increasing the voltage, the CPU gets more power, which makes the overclocking easier to be successful and stable

the core voltage of CPU can be set and adjusted in BIOS (as shown in Figure 7). Under normal circumstances, you can select the default state. If the system is unstable after the CPU overclocking, you can add voltage to the CPU core. But the side effect of voltage is very big. Firstly, the heat of CPU will increase. Secondly, if the voltage is too high, it is easy to burn the CPU. So you must be careful when adding voltage. Generally, you can add it in steps of 0.025v, 0.05v or 0.1V

3. Using software to achieve overclocking
as the name suggests, is to achieve overclocking through software. This kind of overclocking is more simple. Its characteristic is that the set frequency will recover after shutting down or restarting the computer. If rookies do not dare to achieve hardware setting overclocking at one time, they can first test the overclocking effect with software overclocking. The most common overclocking software includes softfsb and software developed by motherboard manufacturers. They all have the same principle, which is to control the frequency of the clock generator to achieve the purpose of overclocking

softfsb is a general software, which can support dozens of clock generators. As long as you select the clock generator model used on the motherboard, click Get FSB to get the control right of the clock generator, and then you can set the overclocking through the frequency lever. After selection, press save to let the CPU start working according to the newly set frequency. However, the disadvantage of software overclocking is that when the CPU can't bear the frequency you set, it will cause a crash or system crash at the moment you click save<

Secret skills of CPU overclocking:
1. CPU overclocking is related to the "constitution" of CPU itself
many friends say that their CPU is still unstable after overclocking, which is the "constitution" problem. For the same type of CPU, the super ability of different proction cycles is different, which can be reflected from the processor number< As we all know, improving the external frequency of CPU is faster than improving the frequency doubling performance of CPU. If the CPU is not locked, the experts will use the method of increasing the external frequency and recing the frequency doubling to achieve better results. Therefore, the CPU with low frequency doubling has inherent advantages. Such as amd Athlon xp1700 + / 1800 + and Intel Celeron 2.0GHz<

3. The more advanced the manufacturing process, the better. The more advanced the manufacturing process is, the higher the frequency can be achieved when the CPU is over frequency. For example, Intel's newly launched Intel Celeron D processor, which has won wide attention, adopts 90 nm manufacturing process and Prescott core. Some netizens have surpassed the 2.53GHz celeron d to 4.4ghz< Temperature has a decisive influence on overclocking
as we all know, the temperature of CPU will be greatly increased after overclocking, so it is necessary to equip a good cooling system. Not only CPU fan, but also chassis fan. In addition, it is also very important to apply a thin layer of silicone grease on the CPU core to help the CPU cool well

5. Motherboard is a powerful tool for overclocking
a motherboard that can support overclocking has the following advantages: (1) it supports high external frequency 2) Have a good power supply system. Such as the use of three-phase power supply motherboard or single CPU power supply motherboard 3) Motherboard with special protection. For example, when the CPU fan stops running, the power supply can be cut off immediately. Some motherboards call it "burn technology" 4) BIOS motherboard with special overclocking settings 5) Excellent workmanship, preferably 6-layer PCB.

9. Go to the superstar's overclocking software. It's easy to use and simple.
