5. Four 290 graphics cards are selected in the configuration list. This is mainly because the 7990 graphics cards on the market are out of stock, and the performance of 290 is much higher than that of 280x. The official quotation is more than 3k, but it is not impossible to get the goods at the price of 2700-2800 in the actual market, so 290 graphics cards are selected. The purchase of the chassis is particularly important. The game fierce tiger shark chassis with the whole tower structure has good heat dissipation, and the 10 expansion slots are enough to control 4 graphics cards. The power supply is the cool all-in-one water-cooled radiator, and the effect with the 4th generation CPU is quite good. The price is also quite appropriate.

8. Mine card is a graphics card used by wabitcoin. Generally, amd card is used. NVIDIA card is not suitable for mining
to identify mineral cards, first of all, check whether there is a large yellow area on the circuit boards on the back of the graphics card, and some of them must be. The reason is the aging of working for a long time
next, we look at the running points. Generally, the running points of mine cards are lower than those of ordinary cards, such as 3dmark software testing
if the price of the graphics card is several hundred lower than the normal price, it is likely that the card will be used
in fact, you can't tell whether your graphics card is a mine card just by looking at these photos. You can play some games that eat graphics cards very much, adjust the image quality to the limit that the graphics card can bear, and play more for a period of time. If the temperature is not too high (for example, close to 100 degrees), the screen won't go black and the screen won't crash, it's OK
otherwise, search for some software of ing machine on the Internet and the machine for a period of time. It's ok if the voltage is stable.
