Can't really seem to find the answer to this in any other topics - when using cgminer with nvidia cards do you need to install the AMD SDK and drivers?

also, with nvidia cards cudaminer is recommended :)

Thanks Patrick and cancrena.

Yes - realised I should have left a contact address on your website!

I'm solo mining in windows 32 with a NVIDIA NVS 4200M.  I have installed Cuda 5.0 and the latest NVIDIA graphics drivers.  This is the cgminer --ndevs output:

Seems to suggest cgminer can see the card?

I've tried not to overload the card to get it going so the cgminer bat file is:

setx GPU_MAX_ALLOC_PERCENT 30
setx GPU_USE_SYNC_OBJECTS 1
cgminer -o http://127.0.0.1:9332 -u xxxx -p yyyy --scrypt --intensity -5 --shaders 50 --thread-concurrency 1 --gpu-threads 1

Yes I had started the LTC daemon.

I have taken cancrena's advice and installed cudaminer which worked right out of the box! 

Thanks for your assistance on cgminer.
