A9 miner over frequency

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. Generally speaking, the ability of overclocking depends on the frequency. The ability of overclocking with low frequency is stronger. But there are exceptions, but also depends on the indivial, strong physical ability to overclocking is strong. It depends on luck.

4. 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. At present, there is no such thing on the market. Apple generally purchases and matches it, and can't overclock CPU (previously)

in the future, if Intel processor is opened or changed to AMD CPU, there may be.

7. 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!

8. 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.

9. No, open CCC (your CCC version is still relatively new, it should have overclocking), click the graphics card - drop-down box to enter ATI overdrive, and notice that there is a red key sign in the upper left corner... Click it to unlock, then you can carry out overclocking operation, but you should be careful

10. Recently, there are many friends who install computers, and there are many to configure. Here I've sorted out some amd configurations at different prices. It can be used as a reference for installation.
