R9270x mining speed

1. Well, it's pretty slow now

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. Can buy to see the color, do not change color, the kind of yellow

4. At present, it belongs to high-end graphics card. If you play it for three years, it's still middle end graphics card. You can play mainstream games. Just like the previous hd6850, mainstream games have no pressure, and most stand-alone games can run smoothly

5. Mining is possible, but this kind of old graphics card, energy consumption ratio is not high, from the point of view of electricity is a loss

6. There should be no problem.

7. This card is feverish, 256 bit wide, 1280 stream processor, power about 200W, a card needless to say 7850 up mine card, many brands, my graphics card has been using micro star, still stable, suggest hawk clock frequency slightly higher than the normal version, boot 30 seconds fan reverse st, temperature control about 60 is still good. That's all I know!

8. The R9 270 can only cost 4 yuan. The driver problem is limited. Unfortunately, I used the MSI R9 270. The same problem, I called the customer service hotline. They said that the new version of the driver is limited, and the old version of the 12.8 driver should be used. After it is installed, the graphics card will be identified as 7870. However, the 12.8 driver can't drive the 270 card at all. But I can only run for 4 yuan

9. Now you can't make money from the electricity bill by using the graphics card to mine.
