I have to find a 5 m cable first... and i will write back
thank you, this would save me a LOT of money if they work fine with them
Sadly i can confirm it doesn`t work with 5m cable , it is not detected by the board at all.

I can`t sort out why is cudaminer using 50% cpu even with -H 2 , reinstalled driver restarted , but nothing helps , any ideas?
The cpu is intel Celeron 2900mhz G1820
