stractum_recv_line failed (error)

[ghost]

Hello. Constantly written error "stractum_recv_line failed".

Brief description of the device:

• Intel Core2Duo E8400
• 4 Gb RAM
• nVidia GeForce 9600 GT
• Windows 8.1 Pro

Running with "--debug" option produces the following result:

Is it possible to solve this problem programmatically?

[lermen-andrefabiano]

Estou com o mesmo problema, alguma solução?

The solution is not a problem because the algorithm requires Cryptonight CUDA 2.0 and above. For example, nVidia Geforce 9600 GT GPU supports CUDA 1.1

All I was capable of these devices, this coin mining built on SHA-256 (e.g. Bitcoin) and Scrypt (e.g. Litecoin). However, the presence of ASIC devices for these algorithms makes the listed graphics cards are useless in mining. Perhaps there is some exotic algorithms for these versions of CUDA computing, but I do not know about them.
