R9290x Ethereum computing power

1. It's better not to exceed 1100 cores. In fact, 1050 cores are just a little bit more than 1100 cores. Because even if you go up, it won't be obvious. The card game is still the card. Don't exceed the video memory. The core performance of 370 is only average at present. Bandwidth is not the bottleneck. In fact, it's just a little bit more psychological comfort

2. I don't know 7990. I haven't used it, but I used 290x. The general situation is as follows. If I is set to 20, the rejection rate is high, and the speed is a little more than 830k. I set it to 19, the speed is about 822k, the rejection rate is great. The 900K spread on the Internet is after overclocking, and the speed can reach 900 ~ 905. I haven't tested the power consumption after overclocking, but the actual mining power consumption is more than 200 watts. More accurate test, wait until the next shutdown! In addition, 7990 can only have 3 cards (6 cores) at most, and can support 4 cards (8 cores) with crack driver
in addition, 290x mining is not recommended. Because the noise is probably equivalent to the noise in the west of Yingze bridge in Taiyuan.

3. In fact, it's only equivalent to the level of 970... This is a card that has been out of date for a long time. Even if you want to buy it, you should consider R9 390

4.

This video card consumes more power, the minimum power supply is not less than the rated 500W, and the recommended power supply is 650W

it is recommended to buy gtx970 at the same price, although the performance parameters are slightly lower

5. 390 is good
because 390 is relatively new.
there is a gap in performance. In theory, 290x is better than 390, but it's just a lost one.
390 is that 290 is relatively optimized and sold, which is basically the enhanced version of 290 vest card.
but 290x is really old, now buy it, Basically, it's not old stock, it's official turnover and so on. It's not recommended

6. The R9 290 graphics card has 2560 stream processors, and the R9 290x has 2816 stream processors. The performance difference between them is about 10%.

7. Hello, Ruifu garden in Baiyun District

8.

bus line: North Extension of Metro Line 3 → Metro Line 2, the whole journey is about 15.7km

1. Take the north extension of Metro Line 3 from Tonghe to Jiahe Wanggang station after 3 stops

2. Take Metro Line 2 after 6 stops to fly Park Station

3. Walk about 940m to Baiyun District government service of Guangzhou City...

9. One yuan looting is an innovative e-commerce mode. As long as the traffic is handled, it will be guaranteed to earn without compensation. Therefore, there is no need for big platforms to engage in fraud. Netease's one yuan looting, one yuan purchase, Sina's fan looting, and later 58 lucky purchase are very reliable. As for some people think it's a scam, one may be that they don't deliver goods when they are playing in a small website, the other may be that gamblers' psychology is that if they don't win, they think there are scams everywhere.

10. I don't know if anyone has been involved in the calculation, but usually, there are open calculation formulas and detailed data involved in the calculation. The most important data to participate in the calculation must be the data of a third party. That's a fair result
for example, in the case of the one dollar lottery in huilife, the public calculation formula and data are used. At the same time, the welfare lottery number is used as the third data to participate in the calculation. The result is not controlled by itself, so it is fair for the participants
therefore, it is suggested that you can spend a few yuan each time, which is similar to playing lottery. If you don't win, you will get a few yuan. If you win, you will be lucky.
