at the moment, profitable coins (or soon to become) are rather using X11 (or still scrypt... cinni, wc etc..)
I am mining Borgcoin   (I don't think it will become profitable...) and Juggalocoin (it should be profitable)
and BCC should do something (was not able to get a block at the launch)

I will gladly donate my rig for a few days if you get the groestl out

even with quark + groestl speeds to the max there's not much profits to be made.

my rigs are power hungry.

Hehe, I hope Christian is mining it out in the meantime. He deserves it.

Yep. Thats why it would be great to get it released soon

With those hashrates, it would make groestl the highest paying coin of the coins I track as of currently. 

There is a command in sgminer which displays the mapping of the opencl devices and you have to enter to the number given by that command.
This command is --ndevs.
You need to run first cgminer --ndevs (put a pause at the end of the bat file, as cgminer exits right after displaying the info).
It will displays the number associated to each opencl devices (gpu, cpu and even integrated gpu... you need to select the one corresponding to your card)

Don't trust my word for it, but that looks a lot like my antminer U2's when they were on the standard wall supply, switched it to a heavier duty 5V source and now they're all more or less alike.
It could be that your power supply isn't delivering enough current? Are you using power from the motherboard? Maybe that's the bottleneck?

So do you mean --gpu-platform #0 based on this device manager pic or how do I figure this out? and what do you mean run it with a flag? I'm sorry I am apparently a complete noob with all this stuff and I thought I at least knew some things lol.

Great now I'm getting this error again on 2 cards instead of on just 1.

And now 10 minutes later it's happening on 3 cards! Is my computer killing these cards off slowly?

--gpu-platform #number  (you need to run sg/cg with a flag which will dump the mapping of the card... don't remember which param though

Alright we're in business! Unfortunately they aren't as high as I was hoping for these cards and GPU 2 is still being a party pooper and crashing on me and then only mining at 33Kh/s and here's my bat file. D:\Software\Miners\cudaminer-2014-04-12\x86\cudaminer -H 2 -i 0 -l T5x24 --url stratum+tcp://stratum.rapidhash.net:3333 -u User.Worker -p Password

Would you say that one card is bad or something else wrong? I guess I could figure it out when I get home and I can play with the riser and the card and maybe switch it around to see if I can get it to perform correctly. Thanks so much for your help btw. I've poored too many hours trying different clock speeds and different profiles (is that what the T5x24 is? It's called a profile?).

And lastly, I'd like to get my 7970 back to mining now but it says something about there being a bunch of cards on the computer and I think it would mine if in the bat file I pointed it directly at the card to mine with but I don't know how to do that in my SGMiner. Any ideas? Here's what I have in my bat file for the 7970.

That is some pretty good information! I appreciate that. Thanks.

The other thing is system RAM - I have 8 gig. I believe the high n-factor coins use a fair bit of actual system RAM or virtual memory.

To be honest I think that config was posted on overclock.net - I'm really not sure how to fine tune batch size, and if I remember when I tried without or smaller size there wasn't a huge difference.

Are you running on risers? I am straight in to the board on two full size slots. Funnily enough I am actually running two Palit 750 Storm X OC (single fan) as well... I am on Linux though. Using 28/2 version of cudaminer. Usability is not an issue as it's a server that sits in a cupboard and I occasionally log in via VPN

I have been using the card reviews at TechPowerUp.com for getting a good baseline on what the card can be OC'd up to.

http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_750_Ti/28.html (just find the card you have)

I am not exactly sure how they come to their settings, but they have put me right in the ballpark for both of the cards I have right now.

Their reviews are extensive, and the overclock info page has the GPU-Z screenshot of their overclock settings.

I have found that everyone using the +100/+500 terms varies so much based on the card you are using and if it comes out of the box with any OC settings is kind of useless unless you have that exact same model of card.

My MSI 750ti OC 2GB running at their recommended 1145 MHz GPU/1675 MHz Mem and for 3 of my 4 cards that works flawlessly (~295 khash/s). Card 3 seems to not be able to handle that, but I scaled it back a bit until it was stable and figure it is just not a perfect card, but haven't had time to delve any further into that.

I also have two MSI 750ti TF 2GB running at 1210 MHz GPU/1675 MHz Mem. These are hashing out faster than the OC model, and run a good 14 c cooler even at the higher speeds (~325 khash/s).

Unless you have the exact same model the other people's settings will drive you nuts not being able to match... it took me a good two weeks to understand why I couldn't match the settings others were using, but it was because my card was pre-oc'd and only needed another +31MHz on the GPU to get the same settings.

Hope that helps.

put core +106 mem +366
On the bottom of the utility you should see the core clock and mem clock.

wow that worked and they were all mining around 270 base clock and then within a couple minutes it started failing so I think I'd maybe need to change the clock speeds like you recommended. How much do I add on top of the card's clock speeds do you know? I'm using EVGA so it's either plus or minus clock speeds and not set clock speed to x amount.

The current ccminer development version does around 25 MHash/s for groestlcoin on 3 750 Ti cards. EVGA FTW edition, no overclock beyond factory clocks due to running Linux. With a bit of OC, that would be 9 MHash/s per card.

yeh i cant get cudaminer working on my 750Ti or my 780 even using the only launch config from 14-2
