I've updated the OP with what I've found to be an efficient config file. I'm running twin 5830's with 4gb of ram on this machine. I've got CCC 11.12, 2.6 SDK I think ( ) and cgminer 2.11.3. The config file can be further modified for increased speeds. This gets about 260kh/s per card. The reason it's not balls to the walls fast is because of cooling. With summer coming up I may stop it entirely but for now this is staying in the manageable range. tinkering with the clocks for gpu/memory would be best to increase speeds. I hope it helps! This is the config file I'm using: { "pools" : [ { "url" : " http://newlc.ozco.in:9332", "user" : "xxxx", "pass" : "xxxx" }, { "url" : " http://newlc.ozco.in:80", "user" : "xxxx", "pass" : "xxxx" }, { "url" : "backuppool", "user" : "username.workername", "pass" : "pass" } ], "kernel" : "scrypt", "scrypt" : true, "gpu-threads" : "1", "thread-concurrency" : "8000", "lookup-gap" : "2", "intensity" : "18", "gpu-engine" : "0-500,0-500", "gpu-memclock" : "1000,1000", "temp-cutoff" : "95,95", "temp-overheat" : "85,85", "temp-target" : "77,77", "gpu-fan" : "0-100,0-100", "auto-fan" : true, "auto-gpu" : true, "vectors" : "1", "worksize" : "256" }

1. change :gpu - 890mhz , mem 890mhz, intensity 19 ,
2. stay out of 12.10 driver. 13.1 is cool
3 delete *.bin files in cgminer folder
4. install cgminer 2.11.3
290+ kh guaranteed

While running cgminer 2.11.3, when I run this cgminer just opens for a blink of an eye and then closes again. (o.O)

just wanted to bump this up. The only thing I can think of is that I'm running CCC 11.9 or something I think.

Try:
gpu-threads: 1 thread-concurrency: 1024 and ramp up in sums of 64 until cgminer crashes (thats ur limit) eg 2048, 3072, 4096....
Make sure you got at least 2GB ram.

ignore in-file config, its great but has different commands and no support on forums. use command line instead. cgminer.exe --scrypt -o http://newlc.ozco.in:9332 -u xxxx -p xxxxx --thread-concurrency 8000 -I 19 -g 1 -w 256 concurency 6144 and 7200 are acceptable for low ram systems. if 2gb+ use 8000 for best results. intensity below 17 is nonsense. try other software for clocking and cooler controll. in windows trixx for single card, afterburner for multiple.

cgminer.exe --scrypt -o http://newlc.ozco.in:9332 -u xxxx -p xxxxx --thread-concurrency 8000 -I 19 -g 1 -w 256 that seems to work way better. Best so far. GPU0 and 1 are at about 90-98kh/s found a clue for the config file issue: JSON decode of file 'cgminerLTC.conf' failed ']' expected near ':' I can find nothing in the code that looks out of place. may just start a new config file, things are getting pretty whack.

Been working on it for a while, I may have just hit paydirt: { "pools" : [ { "url" : " http://newlc.ozco.in:9332", "user" : "xxxx", "pass" : "xxxx" }, { "url" : " http://newlc.ozco.in:80", "user" : "xxxx", "pass" : "xxxx" }, { "url" : "backuppool", "user" : "username.workername", "pass" : "pass" } ], "kernel" : "scrypt", "scrypt" : true, "gpu-threads" : "1", "thread-concurrency" : "8000", "lookup-gap" : "2", "gpu-threads" : "1", "intensity" : "19", "gpu-engine" : "0-800,0-800", "gpu-memclock" : "800,800", "temp-cutoff" : "95,95", "temp-overheat" : "85,85", "temp-target" : "78,78", "gpu-fan" : "0-100,0-100", "auto-fan" : true, "auto-gpu" : true, "vectors" : "1", "worksize" : "256" } I'm getting about 265kh/s from that with no real tweaking yet.

I'm consistently getting about 265kh/s. I could try to get faster but the heat is going to be too much for my cards, I fear. I did hit about 330kh/s at times with tinkering but with those settings I'd be running the fans at 100% the entire time. I am getting a lot of rejected shares after found blocks.

I'm actually getting about 1 rejected share for every 3 accepted... is this normal? (o.O)
