nvidia CUDA mining help!

Hi all,

I'm very new to all of this!

The problem relates to mining on a Nvidia Geforce GT335M card!

I own an Alienware M11x gaming laptop which, for its size class, packs a fair amount of power under the hood. I have been successfully mining using the i7 CPU but the hashes I've been getting are pathetic (4~5Mhashes range).

I'm keen to harness my GPU for mining...however have been hitting problems.

I'm using guiminer - which I believe is actually rpcminer-cuda.exe for this purpose.

On guiminer things never progress past the 'connecting' stage - and the worker I create for the task doesn't appear to have connected.

I first updated my GPU, Physx etc to the most recent drivers...

I then tried again - no luck.

Finally I decided to dispense with the gui and see what happened if I tried to launch the program in dos.

I launched rpcminer-cuda.exe with no parameters and was immediately greated with the error I suspect is halting everything. It reads (in spanish but I'll roughly translate it below:

"No se encuentra el punto de entrada del procedimiento cuMemcpyDtoH_v2 en la biblioteca de vinculos dinamicos nvcuda.dll"

which means something like:

"No entry for the proceedure cuMemcpyDtoH_V2 could be found in the dll library nvcuda.dll"

Could anyone advise me as to how to proceed?

if it helps my GPU is a Nvidia Geforce GT335M

Many thanks all!
