Why do miners need to overclock and underclock?

Why do miners need to overclock and underclock? Why should the frequency be reduced when the market is terrible and overclock when the market is good? Why can the profit of the miner be changed through frequency modulation? Today we will talk about overclocking and underclocking of the miner. 1. What is overclocking and underclocking? Both overclocking and underclocking are relative to the normal working mode of miners. Overclocking/downclocking essentially optimizes the miner algorithm to change the miner's power consumption and hash rate. It can be understood that the miners can adjust different gears, the low hash rate gear, the normal hash rate gear, and the high hash rate gear respectively correspond to the down-frequency, normal, and over-frequency working modes. Of course, the prerequisite to achieve overclocking or frequency reduction is to have firmware that supports frequency modulation. The firmware can be understood as the operating system of the miner. The miner can ac

How to calculate the residual value of miners? Where do the scrapped miners go?

How to calculate the residual value of miners? Where do the scrapped miners go? Perhaps the most embarrassing thing in the current market is the Antminer S9. If the price of Bitcoin rises a little bit, most of the Antminer S9 can be turned on and continue to use the waste heat; if the price continues to fall, except for the large miners who fill the load or self-built mines and have an advantage in electricity prices, most retail Antminer S9s will Shut down. After the miner is shut down and off the shelf, how much can the miner sell if you want to sell the miner? Where will the miners who have ended their economic life eventually go? 1. Residual value of ASIC miners ASIC miners’ chips  are customized and can only mine coins with fixed algorithms. For example, SHA-256 miners can only mine BTC, BCH, and BitcoinSV. The scrapping of ASIC miners  is a long process. When the mining output cannot cover their electricity expenditures, these miners flow from small miners and retail miners to la

Antminer S15 VS T15 Profitability Comparison

Antminer S15 V S  T15   Profitability  C omparison Bitmain’s ASIC Antminer S15 and T15 use 7nm chips and the SHA256 algorithm for hashing. Antminer S15 and T15 models use two different modes: · Energy saving · High performance In the energy-saving mode, the power consumption of the S15 is only 850W, which is very suitable for use in areas with expensive electricity. On the other hand, the miner power consumption is 1596W under the high-performance model, and the increase in hash rate also compensates for the additional energy consumption. The only reason you can use ASIC miners in saving mode is to reduce heat and noise. S15 Vs. T15 specification comparison: Model S15 T15 Algorithm SHA256 SHA256 Weight 7KG 6.6KG Size 221 x 175.4 x 278.8 mm 205.15 x 175.4 x 278.8 mm The hash in performance mode 28 TH/s 23 TH/s The hash in power saving  model 17 TH/s 20  TH/s Power consumption in performance mode l 1596 W 1541W Power consumption in saving mode l 850 W 1200W Chip manufacturing technology
