try with -w 256 --lookup-gap 2 and --thread-concurrency 6144, 5120 or 4096

then try cranking up the intensity. 16-20 tend to give the highest rates, but lag the machine considerably more than 14-15

well some more toying with it i used the settings below and the hashrate tripled now its going at 310Kh/s but it get incredibly hot im talking 82c so i have to shut it down using a radeon 5830

setx GPU_MAX_ALLOC_PERCENT 100
cgminer.exe --scrypt -o stratum+tcp://stratum.wemineltc.com:3333 -u xxxxx -p 12345 -I 17 -w 256 -g 1 --gpu-engine 950 --gpu-memclock 1250 --thread-concurrency 5600

I always found setting the fan with a program outside of cgminer worked best for me

Try EVGA precision or MSI afterburner. Doesnt matter what make your card is.

i will give it a shot i changed the thermal paste on the gpu and i set the fan speeds to raise with the tempature with msi afterburner thanks for everyones help

I've never been able to get mine working either, even tried other currencies. Sad

With more ASICs entering the network I can see this becoming much more common among GPU miners. I'm planning to switch mine over in the next 48 hours so I'll post back with some results and help when it's all done.

what amd sdk are you guys using when you mine ltc? when i try 13.1 and sdk 2.1 i cant bitcoin mine or ltc mine ive tried 12.8 also didnt work the only sdk i can mine btc on is 2.1 and catalyst 11.6 so far so maybe i should try updating the sdk to get ltc working? im running out of ideas

I'm running a 6950 and 5850 with Catalyst 13.1 - no need to install SDK with that version.

I tried like 10 different versions, and reinstalled Win7 before getting to this point though. Now I am having no issues except for my 5850 going SICK and DEAD, but I have cgwatcher to help me combat that.

Are you overclocked? I had a lot more difficulty mining LTC when overclocked than BTC just due to the much higher RAM usage on the video card.

i did a fresh install of windows 7 earlier and yes it mines btc with cgminer but ltc cgminer just crashes

What pool are you using? Post up your command line.

Is it just opening the command prompt window and immediately exiting or is it crashing after a specific point?

I was getting nonce errors with mine in cgminer, but that was cleared up when I did a fresh install and used 13.1 instead of 13.3

Can you mine BTC with it?

When I first set up my 5850, I could use GUIMiner on BTC, but couldn't mine any scrypt coins. I did a fresh install of Win7, put 13.1 on there, and then everything worked fine.

It takes a little bit of work. I am using a 5850... had a few problems when I first started. Reinstalled windows, and am using Catalyst 13.1 now with no problems.

Can you get it to work with GUIminer? If so, then it might just be a problem with your cgminer command.
