Example for Litecoin Mining on coinotron pool with GTX 660 Ti
cudaminer -d gtx660ti -l K28x32 -C 2 -i 0 -o stratum+tcp://coinotron.com:3334 -O workername:password
Anyone else getting infinite "result does not validate on CPU" errors with this settings?
I have an Asus GTX 660Ti OC
I think you need to use k instead of K for 28x32, as far as I understood from christian's post. K = Y in new release. I am using K7x32 for my 660Ti non-OC.
Here is how launch configs from the cudaminer 2013-12-18 release translate to cudaminer 2014-02-02 release
to get equivalent performance. This can be handy if you find some older launch configs posted by others
L b x w -> sorry, legacy kernel was replaced by Fermi kernel. Autotune the F kernel.
F b x w -> F b x w ( no change to this one )
K b x w -> k 4*b x w (the previous K kernel is now named k and no. of blocks has to be quadrupled)
T b x w -> t 4*b x w (the previous T kernel is now named t and no. of blocks has to be quadrupled)
S b x w -> Spinlock kernel is GONE.
These following kernels are new in the cudaminer 2014-02-02 release: T (nVidia), K (nVidia), f (ported over from David Andersen's code).
