A9 miner overclocking firmware

1. A9 is still considerable in terms of current revenue. Now it's about 620 yuan a day. Because the income of the first group of miners who used this mining machine to mine is still stable, and the initial income is also 550-650 up and down. The price may not fall, but will rise. Now the currency price is rising steadily, driving the price of mining machinery is also rising. There is also a serious shortage of cash on the market

2. How much do you buy your A9

3. Go to the BIOS memory settings. Yingtai board overclocking function is very strong, there should be corresponding options. It is recommended that you look for the motherboard manual to find this option.

5. The students have good insight, and they have noticed the 6575. At present, the official MTK said that the MTK 6575 is based on the single core A9 plus power531 (that is, the enhanced version of 530). It is estimated that the 531 should be over frequency, and the 6575 is based on TSMC 40nm Technology, which is stronger than Qualcomm 45nm. Generally speaking, the same frequency 1g, A9 is 20% stronger than A8, The 531 of GPU enhanced version should be the same as the 205 of Qualcomm, so the theoretical performance of 6575 is better than that of 8255. I emphasize that in theory, but in fact, MTK official has made it clear that the competitor of 6575 is the 7227a recently launched by Qualcomm. The 7227a has a 45 nm A5 architecture with a frequency of 800m to 1g (currently 800m), while the GPU is a tragic 200, 6575 and 7227a are both smart phones with the main attack of less than 1500 yuan. There is no doubt that 6575 can beat 7227a in performance. Why can't the official say that it can beat 8255? It's estimated to be an indefinite number, but one thing to be clear is that the maturity of 8255 is 8255 second kill 6575, you know, 8255 has been out for so long, and optimization has been on two levels, so if it's not real machine comparison, it's hard to say whether the actual 6575 or 8255 is better than 8255. In theory, 6575 is better than 8255. In addition, Huawei has launched the k3v2 quad core A9 processor, which has been demonstrated on real machines. It is said that it is 30% better than T3, which is more power-saving than T3. Its performance is currently the most powerful arm processor in the world. Are the first fresh information, hope to adopt!

6. The performance of a9x single U is undoubtedly the super frequency version of A9. As you all know, the super frequency is controllable, that is, the temperature is stable enough. The performance brought by super frequency is almost proportional to the main frequency (AMD powder, please ignore, refers to Intel). The main frequency of a9x is increased by 22%, and the performance is also improved by so much (geekbench is more than 2400, and geekbench is more than 3100), Therefore, it can be inferred that its architecture and process are exactly the same, while a9x uses metal heat dissipation, and the surface of A9 is only the previous plastic.

7. The A9 series includes a9000 (A9 2016) and a9100 (A9 high configuration version). The latest versions of the two machines are Android 6.0. If the mobile phone has a new firmware, there will be a push update notification. You can perform the following operations: settings - (about mobile phone / about device) - System Update - Automatic Update - turn on.

8. There are many reasons for black screen.
first, it is caused by virus. Try to kill the virus completely.
Second, there are system problems, or there are conflicts between software and hardware, which can be solved by re installing the system.
Third, there are problems with the graphics card, such as the driver of the graphics card is wrong, or the graphics card is broken, or the graphics card is loose. Clean the st of the lower chassis, and wipe the golden finger of the graphics card with the image skin to see if it is magnetized,
the fourth is the hardware problem, such as the memory mole, CPU, graphics card, motherboard, etc.
5 display problem, the display is broken
6 the hardware acceleration setting is too high, which is beyond the frequency range. Click Windows Start menu control panel double click display troubleshooting tab, and under hardware acceleration, the, Graally drag the slider from "all" to near "None" -- click the "OK" button
7If BIOS is not set correctly or overclocking is not successful, the black screen can be restored to the default value by discharging the main board.
8If you open a program, the screen will be black. For example, if you play a game, one is that the graphics card fails to meet the requirements of the game, and the other is that it conflicts with the program, resulting in black and crash.
9 in Microsoft's black screen plan, it is recommended to reload the system
