cgminer is not using the GPU

[Fibonacci]

Hello.

I'm trying to mine on Slush's pool using cgminer. I had previously gotten a hashrate of 23 Mhash/s (and a nice heater for my room) using GUIminer.
Running this command, instead, I barely get 5 Mhash/s, and the graphics card is as cold as ever:

Code:

cgminer.exe -o http://stratum.bitcoin.cz:3333/ -u user -p pass

How can I fix that?

(Before anyone comments on the inefficiency of my mining hardware, let me state that electricity is basically free for me, so that is not a concern)

What graphics card are you using?!

What hash rate should you be getting?
Check out this list here and see where you should be.

My graphics card is an Nvidia GT 650M, which I couldn't find here (at least not that exact model). But as I stated, I was getting about 23 Mhash/s with GUIminer.

How high is the intensity?

How high is the intensity?

Didn't specify an intensity on my original command line. But adding, say, "-I 18" changes nothing.

Try lower or higher intensities anywhere between 13-20. I got a 7970 and it performs best at 13.

Try starting with --intensity 1 and go upwards to see if that helps.

Once CGMINER is running you can use the on screen controls to tweak it's settings to see the results in real time.

I believe you push G (For GPU Management), and I for intensity, type in the new number and hit enter.

You can see what effect it has immediately.

For more detailed information about how to use / tweak cgminer, have a look at the following thread :

try changing "gpu-platform" : "0",
to 1

try changing "gpu-platform" : "0",
to 1

Before doing that however, you should run

Code:

cgminer -n

in a terminal.  It will tell you what gpu-platform choices it detected on your computer.  From there you can decide which one you need to be mining with.
