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

In the Beginning there was CPU , then GPU , then FPGA then ASIC, what next I hear to ask ....

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

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

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.

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