GPU for Nvidia cards - help pls

[HurrDurr|Lafara]

Hey everyone out there (:

I have a question about "how can i enable GPU for my Nvidia card"

Graficcard: Nvidia GeForce GT 520 MX
Processor: Intel Core i7-2670QM

If i start guiminer make a new OpenCL miner i can only take "GeForce GT 520MX" and set the CPU affinity.
So now I'm mining with CPU 5 - 6 MHash/s
Is there any way I can enable GPU for my card and mine with GPU ( 5-6 MHash/s is really slow)

Would be nice if anyone could help

from the command line in guiminer type
poclbm.exe
and see what it says - you will probably need to point the device to the card
i.e.
-d1

If I open poclbm.exe in the guiminer folder it closes itself immediatly after opening...

Is this a laptop with switchable graphics?

yes it's a laptop but i dont know if the graphics are switchable

Please note that CPU and Nvidia mining is VERY SLOW, you are just wasting time and electricity
An ATI is much faster

Yeah i know that, for that i want to change to GPU but i dont know how...

It's impossible to change the GPU for most laptops.

hmm.. i dont want to change the GPU. I will try to explane my situation^^

I have a Nvidia grafic card (GT 520 MX), I know that it's possible to mine with GPU with that card, but when i start guiminer and want to mine i only can select "GeForce G 520 MX" and i can select on how much of my 8 cores i want to mine, so the only way i can mine is with CPU. And my question here is how i can enable that i can mine with GPU with my grafic card.
hope this is intelligible

EDIT: i installed GPU Caps Viewer and under GPU it says "unknown", dont know why

Use this.

Run using CMD as RaTTuS said above.

then it says:

Traceback <most revent call last>:
  File "poclbm.py", line 48, in <module>
pyopencl.LogicError: clGetPlatformIDs failed: inavild/unknown error code

EDIT: I'm now mining with rpcminer-Cuda 10-11Mhash/s . It's the best i get or can it also be better?

GT520 is a pretty low-end card, so yes it seems adequate. Comparable really with the about 13MH/s I was getting with a 9600GT.

ok thx for the information

Yes this sounds about right.  Does anyone know why it is that Nvidia cards are so much worse than ATI?
