Small bug here? When I set -I 20 this happens: (with 1x HD 5770)
That's not a bug. That's just being stupid. Switch to -I 7.

According to NIST and ECRYPT II, the cryptographic algorithms used in
Bitcoin are expected to be strong until at least 2030. (After that, it
will not be too difficult to transition to different algorithms.)

I'm on windows 8 with the latest cgminer. I find that I have to reset cgminer atleast 1-2 times a day because it hangs on my 7970 running only at 1000/1000.
The last message is usually "Pool 0 stratum share submission failure" but it fails to connect to my alternate pools. My windows 7 rig with 4 GPUs never has this issue and has been going for weeks on end. Is there any incompatibility with windows 8? I have made sure that all firewalls on my computer have full permission for cgminer as well.

Taken right from the FAQ in the very first post of this thread: Q: I'm getting much lower hashrates than I should be for my GPU? A: Look at your driver/SDK combination and disable power saving options for your GPU. Specifically look to disable ULPS. Make sure not to set intensity above 11 for BTC mining.

Yeah I read that and it has nothing to do with my error since I'm getting way to HIGH (read, not LOW) hashrates. I normally get 170Mh with -I 4 and when I tune things I get around 200Mh, but NOT 3000Mh.

BTCGuild web interface reports ~50MH/s
Your hashrate is lower than it should be.

Find out what version that number is - it may (or may not) be a problem. As for Platform - when reading the README, search for the word "platform" (F3 or Ctrl-F or whatever the search key is) You have an unusual setup - so you will need to read and understand more of the README ...

Hi all
I've been trying to mine litecoins using cgminer. I managed to connect to my pool ok but after running it for about 5 minutes I had q=20 a=1
I only had 5 minutes but I don't think those results look good. If I was mining for Bitcoin I would have had a lot more shares accepted in 5 minutes mining
Is there something going wrong?
Thanks
EDIT Here is the command line and output:

I can't seem to monitor cgminer (2.11.4) with a web front end (Anubis) when I'm scrypt mining. If I do normal BTC mining it works fine. I've tried to explicitly set the api port to 4028 using the --api-port switch but it still doesn't work.

Why? 4x7950 exactly like your card mines with 4GB system ram with: --scrypt -pool:port -O user:pass --lookup-gap 2 --thread-concurrency 21712 -g 1 -w 256 -I 19 Win 7 64 12.8

Hi guys, I'm trying to mining LTC using 2x5870 with this line: cgminer -o stratum+tcp://coinotron.com:3334 -u xxxx -p x --script
The command "--scrypt" aren't accepted by cgminer!
the output is: [2013-04-07 12:51:40] cgminer: --scrypt: unrecognized option
Then i tried with cgminer --enable-scrypt, but the output is:
cgminer: --enable-scrypt: unrecognized option
Even if the command "--enable-scrypt" is on the README file!
If you want to use scrypt you should write scrypt and not script...

I now have another system to test. It has a AMD Radeon HD 7970M and a intel 3000. Its strange but cgminer.exe -n only shows the 7970M as a gpu, not the 3000. It was another way with an nvidia platform. There were 2 platforms and both gpus could mine.
The thing is... when i start mining, regardless if for bitcoins or litecoins, it starts, then the screen turns black and thats all. The fan is working hard. When i check the hashrate at the pool i see a hashrate going down and more down. Im not sure what happens because i cant see anything. When i try the debug-flag the whole thing is crashing.

Hi there,
i hope its ok to write such problems here.
Its my first try to add some performance using the cgminer. The setup is Windows7 64 and 2x7950.
Thats the error i get right after starting:

Any ideas??

I now dont know further. I installed the driver for intel 3000 gpu, chipsetdriver and newest beta of catalyst for the 7970M. Then installed AMD OpenCL SDK 2.7 because i have read 2.8 is faulty.
But -n shows still only one GPU. At least its the 7970M. It shows Error -1: Getting Device IDs (num).
Starting cgminer brings this error again and then a black screen while the card is running. When i see at the pool (bitparking) the hashrate starts with a crazy high value and constantly drops then even though the gpu seems to run because of high temperature and high clockrates (gpu-z). I believe nothing is sent then anymore.
So what could i try now?
