Bitcoin mining machine evaluation core mining machine T2T-30T


Founded in 2006, Core Dynamics, the parent company of the core mining machine, has 12 years of experience in IP/IC development and design. In recent years, the focus has shifted to the development of Bitcoin mining machines. Scrypt, X11, CryptoNight and Blake256 have been launched. , Blake2B, Equihash, CryptoNight and other algorithms of a variety of bitcoin mining machines, models cover all major currency mining machine algorithms. The core moving machine T2T-32T is a relatively new bitcoin mining machine for the core mining machine. The following RHY brings the evaluation of the core mining machine T2T-30T.

1557134586260.jpg

Core moving machine T2T-30T parameters:


Calculation power: 30TH/s (+/-5%) sha256


Power consumption: 2200W (+/-10%)


Power consumption ratio: 69W/TH


Size: 460mm*160mm*236mm


Note: Built-in ASIC Boost function


The core dynamic mining machine T2T-30T adopts an all-in-one design. The power supply and the main unit are integrated together. The whole machine size is 460*236*160mm and the net weight is 14.2kg.


There are 4 kinds of mining modes preset in the core moving machine T2T-30T. The fan speed will remain at 30% during normal operation of the mining machine. The noise level is between 77-80 decibels, reaching the preset temperature warning value of the mode. The rear fan starts to run at a high speed, up to 100%, and the noise level is 88-91 decibels. After 3-5 minutes of cycle, the power consumption will vary by about 100W, and the noise level of each mode is close to ▽.


The temperature value will vary depending on the mode. The air outlet temperature from low power mode to high performance mode varies between 51 and 70 degrees.


Comparison of the preset mining mode in the core mining machine:


Efficiency (low power mode): The mine machine runs in low power and low power mode, the temperature warning value is 55 degrees, the average power is 27.9T, and the power consumption of the whole machine is between 1940-2037W. For 69.5-73W/T▽


Balanced: The recommended mode for balancing power and power consumption. The temperature warning value is 60 degrees, the average power is 29.5T, and the power consumption of the whole machine is between 2204-2265W. At this time, the power consumption ratio is about 74.7-76.7W/ T▽


Factory (factory mode): Factory default setting mode, the temperature warning value is 65 degrees, the average calculation power is 31.6T, and the power consumption of the whole machine is between 2217-2350W. At this time, the power consumption ratio is about 70.2-74.3W/T▽


Performance (High Performance Mode): High power and high power mode. The system will prompt this mode to be the overclocking mode of the mining machine. Please ensure that the power supply and the wire can support the high power load in this mode. The temperature warning value is 70 degrees, the average calculation power is 33.8T, and the power consumption of the whole machine is between 2370-2512W. At this time, the power consumption ratio is about 70.1-74.3W/T▽.


By pulling the mode progress bar to the far right, the mining machine mode can be modified to “Performance+” mode, which can achieve overclocking of the mining machine, but puts certain requirements on the power supply, as long as the power supply does not have a protection mechanism, it can be appropriately small. Overclocking.


Performance+ mode: The runtime system will also prompt that this mode is the super-calculation mode of the mining machine. Please ensure that the power supply and the wire can support the load of high power consumption in this mode. In this mode, the optimal frequency will be automatically adjusted in the first half hour of the mining machine. The single power board will fluctuate between 7.7-11.8T, the maximum calculation power can reach 34.8T, and after half an hour, it will stabilize at 34T, and the power consumption is 2450- In 2602, the temperature warning value is 72 degrees, and the power consumption ratio is about 71.8-76.3W/T▽.


Core mining machine T2T-30T evaluation summary


1. The core moving machine T2T-30T uses an integrated machine design, the housing temperature is well controlled, it is convenient for the mine to maintain the upper and lower shelves, improve the efficiency, the volume and weight are slightly larger than other mining machines, and the noise level is also slightly higher;


2. Preset 4 kinds of mining modes can be switched freely according to needs, convenient to control energy consumption, each mode is about 2T higher than the previous mode, and the high computing mode after overclocking has certain requirements on power supply and wire. , can be properly overclocked, as long as the power supply is not protected, no problem, the maximum computing power of the whole machine can reach 34T / S;


3. Both front and rear fans are equipped with metal protective cover, and the bottom is also equipped with anti-slip mat to ensure the safety during mining production;


4. The calculation level of the whole machine reaches the official parameter. The lowest power consumption ratio is 69.5W/T, and the calculation power is 27.5T/S. After 24 hours test and short overclocking test for 4 modes, the mining pool receives computing power. Smooth curve.
