Advantages of the Avalon2 mining machine chip:

 

1.The world's first developed, mature, stable  technology

2. Excellent performance;Official nominal speed, but almost everyone has used in overclocking

3.The cycle environmental protection concept: also for customers to save money, let you of the generation and value at the end.

The 2 generation of the 55nm chip will keep the same physical size as the 1 generation of 110nm chip. There are  only littile changes, 

because very small one can let them installed and tun on the original operation panel .

4.optimization technology: avalon has released the ongoing project code for MM (Miner Manager). This project has LM32 core and SHA256  

hardware acceleration technology. It is more than just A3255 Avalon2 generation, it can be used for any other currency optimized ASIC mining machine.

 

Superior raw materials: 4 layer Blue Gold - two times that of copper PCB, fully enclosed inductance, tantalum capacitor. High quality materials can not only increase the stability of mill work, 

prolong the working life of the mill, it can also not make limits on the electrical performance for those water cooling equipment overclocking players !

 

 

Warranty: 1 year free maintenance service (not including Avalon computing chips)
