wholesale beaded jewelry 9 California Ethereum ETH Miner is sold?

dreamland jewelry wholesale The purchase of the Ethereum mining machine is generally two ways. One is to purchase through the official website of the Ethereum mining machine, and the other is to purchase it through the second -hand dealer of the Ethereum mining machine.
Is when buying an Ethereum mining machine, be sure to avoid the following lightning areas:
1. Second -hand graphics card
Take the opportunity. Whether it is a graphics card or a graphics card mining machine, there are not new graphics cards in some packaging, but simply refurbishment becomes second -hand or bad graphics cards. Xiaobai or ordinary people cannot distinguish it at all. Such machines often have insufficient computing power and high failure rate after assembly.
2. Brush BIOS tampering graphics information
The most important must be the graphics card. The performance and number of the graphics card directly determine the computing power of the mining machine. Some people will swipe the firmware in the card mines to tamper the graphics card information, which improves the computing power and reduces the performance in the machine to sell the price.
The BIOS mentioned here, it is a control program, controlling the various states of the graphics card mining machine, with core operating frequency, memory operating frequency, power consumption limit, working voltage, memory timing and other core parameters. Swipe BIOS is to use new control programs to tampering with certain core parameters of the machine. By swiping BIOS, you can change part of the information of the graphics card, so that people cannot judge the graphics card encapsulated in the mining machine at the core of the GPU to achieve better energy efficiency Compare. If the graphics card on the market is swiped with BIOS, then the manufacturer will basically not provide warranty services.
etH2.0 has been mentioned for many years. For Ethereum miners, ETH2.0 is like the sword of Damocles hanging above the head. Once ETH2.0 is developed, millions of uniform networks on the Ethereum network Mining machines will be eliminated. Except for a small part of other currencies, most graphics card mining machines will be thrown off in the secondary graphics market. This is undoubtedly a disaster for Ethereum miners who have not returned. Investors have made new requirements for the purchase of Ethereum mining machines.
