Hello, I'm french and i just begin in mining
I try to mine ZCASH with old Nvidia GPU (9600GT). But, when i run the miner, it closes instantly. I can read before close, "Error: Cuda driver version is insufficient for cuda runtime version" ... I don't understand
I have install CUDA 9.1 and 341.92 driver
Maybe I should have install CUDA 6.5 ??
Can you help me please

(Sorry for my bad english

)
Matt
First of all, you should always give basic info as What OS you're using, what mining software, etc...
9600GT isn't a CUDA GPU Looked at wrong GPU. The 9600gt is far to old and has far to little ram to be useful or even capable at mining such coins at all.
I'd recommend looking for a second hand 1070 or 1060.
