I'm trying to run cudaminer for the first time on my GTX 480 SLI cards.  This is Windows 8 (not 8.1 to my knowledge) with latest beta driver (331.65) from Geforce experience.  When I autotune it crashes after picking a kernel and I'm not sure how to get useful info.  I do have some of the CUDA SDK installed on my computer, but haven't touched it recently.  Was years ago I last programmed something CUDA, and installed it more recently on a whim.  The last few lines of a failing run with debug turned on is below...

I tried the idea of limiting which kernels to use.  When I picked Fermi (which my card is) it crashed again.  When I picked Kepler I got farther, but this still seems wrong not least of which because this is not a Kepler based card and the errors from card 1.

Thanks for any help in advance.

----------------------------------

Just realized SLI was turned off in the driver.  I'll try with it on in a bit...

I've got two NVIDIA GTX 480 cards installed in my Windows 8 PC with the latest beta driver installed (through Geforce experience).  I was hoping to try out Litecoin mining, but every time I run it I get a debug pop-up right after the autotune process happens and cudaminer declares a kernel to use.  I'll copy/paste it in here (with minor edits to clear the machine specific stuff) in case it helps diagnose the issue.

cudaminer -D -H 1 -i 1,0 -o stratum+tcp://<url> -O <user>:<pass>

I was hoping to get help before posting an issue on github.

The rules under https://bitcointalk.org/index.php?topic=177133.0 say...

"You can only post in the Newbie and Local sub-forums till you have made one post and waited 4 hours. This post must be substantial: at least several sentences."

So either you haven't waited 4 hours beyond your first post, or your first post was not "substantial" enough.  I'm in the same boat.  Here to ask about a crash in cudaminer, but am not sure how hard it is going to be to get out of newbie jail.
