I’m just starting using FTC but cgminer + nvidia caused me a lot of problems, any experienced user can help me?

Have you installed the NVidia driver?
And also I’m assuming your on Linux? Which distro / version? And what graphics card do you have?
Could you also post your cgminer config

Thx guys for response!

About my config:

It is Ubuntu 14.04.1 LTS and nvidia 750 cards. Nvidia drivers - 340.21-0ubuntu1 are present in system. I can mine all other coins with ccMiner. I dont use cgminer config - i’ve tried to run -n or --benchmark just to check if it’s works.

Any ideas?

kris_davison

Thats great cheers.
I meant what is your shell command to start cgminer?

For my 750ti’s mine is something like this

./cgminer -w 128 -l 15 -g 1 -I 17

Obviously with host and user/password options too.

I’ve tried only:

./cgminer -n --opencl-all-devices

and

./cgminer --benchmark --opencl-all-devices

Could you try to run these commands and show me an output?

Regards!

kris_davison

Ah OK I’ll will try those next time I get a chance. (Tomorrow night I think)

Anyway its worth trying this command to check if it works.

./cgminer --neoscrypt -o http://uk.mine-ftc.co.uk:19327 -u -p

Setting -u to your Feathercoin address
And -p to anything as its not used but must be set.
