It's a GTX 670. has 1344 cuda cores. 1344x32 works at -L 512. No matter what I specify for -L, doubling doesn't work. Out of memory every time.
but can't you just ignore the out of memory? it's for scrypt related buffers mostly, which keccak doesn't need.
maybe -L 1024 -m 1 does the trick?
Nope, it actually crashes. It starts putting out crazy hashrates, but if you check the GPU load you can see it actually gave up and isn't doing anything.

For the kernel launch configuration: Take the total number of CUDA cores on your card, multiply by 2, and append x32 for the K kernel and x16 for the F kernel. Don't bother with the T kernel for the moment.
This should give somewhat higher performance than the original 1000x32 or 1024x32 configurations suggested in the README, especially on the biger cards like GTX 660Ti, GTX 780, etc...
Use -L 512 with these huge launch configurations or out of memory is guaranteed. But on the other hand, these out of memory errors don't prevent keccak hashing (the program just continues...). Cleaning up these unnecessary memory allocations would be the next item on my "finish the keccak feature" TODO list.

I tried this. but got out of memory errors when doubling. However, not doubling worked for about a 5mh increase. (-l 1344x32 -L 512)
GTX 670 if anyone else wants to use it.

Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
christian something has gone wrong i am hashing all over the place now, as low as 1Mhash/s
at 45/64
every failure is a duplicate
EDIT: i just saw as low as 500khash/s being done and that gets me the share accepted! lol
99% gpu load the entire time and now down to 54/85
EDIT 2
so bad i have had to close the miner
Restart your PC and see if it gives you the same problem. I had this issue with the 12-18 version, seems my drivers had somehow stopped giving a damn. Rebooting reset it.

I have 3x GTX 780 going at it solo and still found 2 blocks today, even with the big difficulty spikes. Solo mining still seems way more profitable with the odd block a day giving 96 coins vs what you'd get at a pool.
I have to restart my cudaminer once every minute because of massive amounts of boo's, but so far I've gotten 4MaxCoins from poolmining in like an hour... that's with 1x 780Ti. Wish this damn stratum crap would go away so I don't have to monitor my miner...
You downloaded the 2-7 version right? There was an issue with the stratum. As long as you've done that, there's no need to restart your miner. the boooos will clear themselves when the stratum picks back up, restarting probably won't save you that much.

Guys, so no pool currently works well? Any recomends at all? I'm currently using rocketpool and submited over 1000 shares, but they don't seem to register at all in the system.
Mine were registering until the last hour. The pool is under heavy load, maybe DDoS as well, and it keeps dropping out. PPLNS may be lagging behind.
