I'm fairly new to this litecoin mining stuff. But I can't seem to make this work. Once I start it it instantly crashes Nvidia drivers. I read readme file and here's my config:
cudaminer.exe -d 0 -l 290x2 -o http://coinotron.com:8322 -O myuser:mypassword

My gfx of choice is a 660ti by gigabyte

Coinotron is stratum based pool. You need to use a proxy miner to use it

Also when mining freicoins? I thought it was only BTC, LTC and TRC.

Oh yes you're right, but is freicoin SHA256 or scrypt based?
you need to change the algo to SHA256

Try it with just: cudaminer.exe -o http://coinotron.com:8322 -O myuser:mypassword

It will run an auto-tune routine for 3-5 minutes than should settle in and start mining. I have a 660TI as well, and my card doesn't seem to like to start with hard-coded launch configs either.

Odd. This was using the GTX 480. I haven't gotten a 32-bit compile to work on 64-bit Ubuntu 12.04 LTS because of the curl library:

checking for libcurl >= version 7.10.1... yes
checking whether libcurl is usable... no
configure: error: Missing required libcurl >= 7.10.1

sudo apt-get install libcurl4-openssl:i386 gives
E: Unable to locate package libcurl4-openssl:i386

Installing libcurl4-openssl-dev:i386 wants to replace everything with 32-bit equivalents. Ummm... no. Apparently the problem with curl is that curl.h is different in the 32-bit and 64-bit versions, so you can't have both in a standard dev install.

OK...I was able to install a 32-bit curl in my home directory and force the compile to use it. The 32-bit binary works on the GTX 480. The 64-bit compile is broken.

The GTX 480 has gone from 137 khash/s to 173 khash/s, and now prefers a 30x7 configuration.

Unfortunately it's still broken on the K20. I get all 0 khash/s even with the binary that works on the GTX 480.

Workaround for constant crash on exit.

Every time I went to exit the program (Ctrl-C) it would crash. Sometimes the driver would auto-recover, the screen would go black for a few seconds, then return, so I could answer the prompt and exit the program. Other times my driver would not auto-recover and I would get a black screen that lasted until I eventually hard rebooted my PC.

Anyway, I discovered that if you unplug or disable you network connection and wait for the timeout messages to appear, usually within 15 seconds, you can cleanly exit. While not an ideal solution, it sure beats taking a chance on getting the black screen and having to hard-reset your box, risking data loss, etc.

I agree with others that further CUDA optimizations would be the best use of the developer's time, so thought I would share this work-around for others who may also experience the "crash on-exits" problem.

It's amazing what you've been doing. With the update my 460 1GB is now getting a max of 97.4Kh/s when it was around 77Kh/s with the previous update. A huge step up from the 63Kh/s I was getting with cgminer. I also seem to be getting less stales.

The linux compile seems broken. Autotune gives all 0 khash/sec.

Tuned just fine on Ubuntu 12.4, 32 bit, nVidia 9600M GT.

What GPU hardware did you try to run this on, this time? Note that I copied the optimization into the Titan/K20 kernels but couldn't test due to lack of such hardware.

Try the April 10th update. I hope I did not screw anything up apart from making it FASTER.

Looks like a solid 20 kH/sec, or ~ 14% increase, in my case! Nice going!!!!

Stales seem cut down. I'm at 19/19 successful right now

I cut nearly all of my stales by switching to mining through a stratum proxy. My current pool is wemineltc.com - this appears to be a solid operation.

I'll have to join that once.. Once I mine I finish off this 1 coin.

200 with 30x7

Guys, it's best if you post before and after numbers

FYI your previous reported speed was: GTX 570 GPU 822 MHZ receiving 165 KH

GTX 570 GPU 822 MHZ receiving 165 KH Now 203KH
GT 650M receiving 30. KH now 32KH

Stales seem cut down. I'm at 19/19 successful right now

Anyone know if there wallet that does auto transactions? Like for every coin I bring in...it send a few to someone else?

It's called a leaky wallet. That will be my next project.

Great!

because if you can get that increase I'll be doing near 300 I think

maybe I'll be buying another 570... or maybe looking on ebay for 590 to test Cheesy

By popular vote, I will be further optimizing the CUDA code.

And boy, do I have some aces up my sleeves: Huge memory transactions (ulong4 vectors where each thread pushes 16 bytes around the block)

The test laptop I am testing on just jumped from 4kHash to 6kHash. So that's a 50% increase.

Yes, there are ways to jump the memory barrier.

Donations please! Wink

EDIT: My GTX 460 just jumped from 72 kHash to 93 kHash. Wow.

I'd like to do this for Christian.
