@cbuchner1 I have compiled a few versions of CudaMiner (along with instructions) for Mac OS X users: http://www.johnchapman.net/cudaminer/

I plan to compile an OS X version for each future release (as long as they compile ;-)).  Thanks for the great work!

I get 230-250 khash/s on my standard 2GB GTX670. Does this sound about average  for a 670?

I have gpu core clocked +100MHz and memory at 1550MHz.

My settings are -i 1 -l K7x32  -C 1 -H 1

K14x16 works well but K7x32 seems to be more consistently high.

I use -i 1 because 0 makes my PC stutter too much. I need that extra power for general usage.

Using -auto always results in a statement saying the results would yield something like 300khash+ but when I run the settings it suggests, I just get 100khash or so.

Also, does memory amount on gpu matter? Cudaminer is only using half of the 2GB available. How do I adjust the memory usage? I thought more memory helps mining.

Is Scrypt jane heavily dependent on memory available? If so how are 6GB Titans performing?

I used the dlls from the x64 folder of the 18-12 release.
Also, autotune crashed for me: -b 2048 -L 3 -i 1 --algo=scrypt-jane
Edit: It doesn't crash with -L 4, getting me ~4.25 khash/s

Can you explain what you did, I have the same problem and which ddl's were responsible ?
Thanks

That makes sense, silly me :p works now

You might want to check if you're using x64 dll's in the executable folder

I read it makes a big difference, so I want to try...

X64 versions neither work for me, but I'm happy with the x32 one.

How can I compile a x64 version?
When I select Release x64 and try to run it, I get an application error: 0xc000007b...

I'll have to test this on my 4GB GTX 660 Fermi card. But I do not think I will see a great benefit from -L 2 or -L 3 because the card has plenty of memory.  Some of the more powerful Fermi cards with memory between 1 and 2MB will benefit greatly I think (GTX 560Ti and up...)

@cbuchner
Big thanks, new version works.
Even better, hash rate went from Thursdays build to current build from 0.63 kh/s to a whopping 0.93 kh/s! (with -L 2 and -l X54x2 and -i 1)
Will test some more -L variants

Isn't K59x2 is for -L 2?

Am I missing something obvious here ? If I let it autotune, it's best is around K59x2 (GTX 660).

 If I try to specify that manually :

cudaminer.exe  --algo=scrypt-jane -d 1 -l K59x2  -H 0 -o stratum+tcp://yac.coinmine.pl:9088 -O user:pwd

 I've used the latest code , building in Release x64.

I can confirm this now. I probably screwed up when adding the lookup gap support.

EDIT: it is fixed now.

Yac takes a while to fully confirm on http://yac.coinmine.pl/ It will slowly change over. So dont worry, you'll get paid.

I'm finding YAC to be falling at the moment, it might be better to look at other coins.

I think Christian meant that the performance / price/ power consumption ratio is better for gtx 660 ti. He is getting more than 5kh/s on his 780 but seeing how a much cheaper 660 ti gets close to that... I am getting ~5.5kh/s on my GTX 660 SLI as well.

 Talking about YAC, any idea what's up with that ? http://yac.coinmine.pl/ - does everyone else get such a high number of unconfirmed ?

Hmm it seems that in the latest build is the X-Kernel not anymore working on my Fermi.

It works when using the Fermi kernel, but sadly that means lower hash rate (from 0.64 to 0.41). Back to using older build.

Should be able to mine microcoin with the github version now, although given that its N factor is still low, performance won't be very good (It will be cpu bound by keccak). I believe cbuchner has plans to eventually push keccak to the GPU, but until then you might be better off with a scrypt-jane patched cgminer, although I haven't seen any binaries floating around so you might be stuck compiling that yourself as well.

I've just managed to get a personal stratum pool up and running. After several hours of fiddling with node.js implementations that weren't really cutting it I finally just set up MPOS. So now I'm thinking about doing some stratum modifications to include scrypt-jane parameters in the job transmissions, which would require modifying cudaminer to change configs on the fly. It would be nice to have config file where I can specify something like "GTX 780: 13, T12x32, L2 : 14, T12x28, L5" Right now I'm having to write scripts to handle different coins, configs, pools, and gpus. Eventually I'd like to set up a scrypt-jane multipool.

Cbuchner why is your 780 doing so poorly? I thought you were getting 3.6 kHs before lookup gaps. It looks like several of us are getting 5+ on Yacoin now.

I would try using autotune to get another config and see what happens.
