cudaminer.exe is currently a 32bit executable.
Someone else posted a 64bit build in the bitcointalk cudaminer thread.
Maybe try this one.

When I leave it up to autodetection, cudaminer only finds the Tesla
K40c's, leaving out the K6000. When I force it with -C 2,2,2 it crashes on
startup.Here's the output of cudaminer (2013-10-10):

+------------------------------+---------------------+---------------+Any ideas what's going on here? Odd that cudaminer finds the Tesla's as
GPU #0, and #1 #1; when
NVidia-smi reports them as GPU #1#1,
and #2 #2. It is because
the K6000 is running WDDM? I have another rig with a K6000 running Linux,
and it's working just fine. Maybe K6000 on Windows is a bit iffy? Is it
perhaps a 4GB memory barrier issue under WDDM on Windows, even though the
card has 12GB? The K6000 is the viz card, so I cannot set it in TCC more to
test that theory, unfortunately.Thanks for any help!

The x64 version didn't change anything. Still the same output, with GPU #2 name being all garbled, then crashing.
