Using an Alienware m11x (OG, GT335m), and it seems that Open CL is not working despite a clean driver install from NVidia, downloading the Cuda kit, and then reverting to Dell's official switchable driver. It's also messing with Folding@Home, so I'm pretty sure it's not any specific miner. Help?

About all I know is that if I try and run a cmd prompt miner, I get something along the lines of "2012-03-12 15:21:51 Error: Error getting OpenCL platforms" except the date is then it happened, obviously.  Roll Eyes Using the Windows 8 Preview with the IE and Chrome, haven't installed Firefox. Would that have anything to do with it if WebCL isn't availible, or different ponies?

Should I try a live disk and see if that changes anything if I open up restricted drivers and let er rip?

Good news, a two year old beta driver actually got it to respond to CUDA commands. Now the fun part.

Did you try this one?

You don't need to install the CUDA Toolkit.

Yeah, but it seems that the newest drivers made it lose support, ironically. I'll try doing a patch install, see if that does anything.

EDIT: Nope, lost Cuda and OpenCL support, but Open GL is 3.3, probably not worth it at this point.

You are using Win 8, right?
Looks like CUDA/OpenCL is not supported yet:
