Graphics card miner at least a few graphics cards

1.

The miner is better

1. the electricity charge for mining with graphics card is very high, and the performance is not high, so it can't even earn the electricity charge

2. mining is an investment more than time and speed. We should try to dig more money in the shortest time. Therefore, the professional mining machines of BTC now stress the characteristics of simple operation, small footprint and low power consumption. For example, Yingtai has developed a professional mining motherboard with a computing power of 23.488g/hash, and the proct model is btc-24gh< br />

2. Mining for computer graphics card requirements are very high, low-end graphics card is not used, so low-end graphics card is not likely to be used to mining.

3. For bitcoin, I suggest adding four black hole superfrequency versions of his hd7970 to the x79 motherboard

first of all, his7970 adopts innovative black hole heat dissipation technology, which is especially suitable for multi card exchanges
another point is that n-card is not recommended. The mining efficiency of a-card is much higher than that of n-card
I suggest you use i7 3970 CPU and 1500W power supply
according to this efficiency, you need to dig for about two and a half years to get back the cost.

4. On the basis of motherboard, 6 cards can be mined by PCI-E X1 extension adapter
up to 7 cards can be mined by expansion card.

5. The standard 6-truck miner has a certain cost performance ratio
the ordinary host you can match casually can't dig enough electricity.

6. Power supply is insufficient or PCI-E does not work, it is recommended to dig
pay close attention to digging now. If it's too late, it will be devalued. Otherwise, even the electricity bill will not be enough.

7. This is related to the number of graphics cards on a miner. Normal 4 cards are common, 1600 * 4 = 6400 graphics cards
if it's 8 cards, it's doubled.

Take a look at the picture, it's not cheap
