2. Lightcoin calculator calculated for reference only, not necessarily real income, recommend several mining graphics card to you, hd7990 R9 290x gold slave miner data card R9 280x

3. Because the mining algorithm is special, the mining efficiency of the graphics card has nothing to do with the interface bandwidth, and has nothing to do with whether there is a fire (several cards can be of different models). The computing power depends on the ability of each card. If six cards of a machine are of the same model, even if all pcielx ports are in the mode of 6X1, of course, the graphics card has the function of high temperature automatic frequency rection, and multi card should pay attention to heat dissipation.

4. It's very easy to judge whether the CPU is working,
disassemble the host computer, press the power on button, and then check whether the CPU fan is rotating
has this problem ever occurred on your computer before
does it crash after a period of work
if it is, the temperature of CPU is too high, and it will shut down automatically. You should help it cool down.

5. Because of the emergence of mining machine, bitcoin mining with graphics card has been basically eliminated after the middle of 2013. Take AMD hd7950 be graphics card as an example, its computing power is 700m. Under the current difficulty, without calculating the electricity charge, it can earn 7 cents a day. At present, the price of a bitcoin is about 3700 yuan.

6. The computing power of different types of graphics cards is different, generally around 22m
it is recommended that you consult the technical customer service of the manufacturer according to the specific model of the graphics card, and the manufacturer will test it.
