Haha! I'm blind thanks. OK got it compiled but no dice, anything over 2048 thread-concurrency throws gpu errors and fails, with 2048 it runs but has all rejects. This is with ubuntu 11.04 with 11.12 drivers and 2.4 sdk probably needs the latest driver/sdk or I just effed it up but it compiled with no errors, I already had reaper compiled and running on here, it seemed to run ok so I just thought I'd give it a shot. I had concurrency problems but 12.6 and sdk 2.6 fixed them.

Yes this definitely needs sdk2.6+
EDIT: and make sure you delete any .bins already generated with older SDKs if you upgrade.

So i did some tweaking on my 3 7970's in cgminer, and i came up with these config settings.. --lookup-gap 2,2,2 --thread-concurrency 8192 , "intensity" : "13,13,13", "vectors" : "1,1,1", "worksize" : "0,0,0", "kernel" : "scrypt,scrypt,scrypt", "gpu-engine" : "0-0,0-0,0-0", "gpu-fan" : "100-100,100-100,100-100", "gpu-memclock" : "0,0,0", "gpu-memdiff" : "0,0,0", "gpu-powertune" : "0,0,0", "gpu-vddc" : "0.000,0.000,0.000", "temp-cutoff" : "95,95,95", "temp-overheat" : "85,85,85", "temp-target" : "85,85,85", "api-port" : "4028", "expiry" : "120", "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "4", "log" : "1", "queue" : "1", "retry-pause" : "5", "scan-time" : "60", "scrypt" : true, "temp-hysteresis" : "3", "shares" : "0", "kernel-path" : "/usr/local/bin" } On cgminer i'm getting 630kh/s per 7970 @1275/1600! Very good job guys! Just another 30kh/s and you be on-par with reaper! EDIT: ok, thanks for the tip ckolivas! I now have 4 threads, but still a no go at 10240 concurrency.

I don't get an increase in rejects with 4 threads, and I let it choose the default worksize for 7970 which is 64, not 256.

Yeah I'm not really sure why I can use 10240 on raper and not on this since they're structurally virtually the same kernels.

I've noticed in reaper, if you tell it to run 5 threads it says it starting 10! Don't know if that has anything to do with it??

There's definitely not enough resources at 10240 gap 2 to run 5 actual threads on a 7970, and since the values don't line up with raper, who knows what it's doing, so long as we get good performance... I've lost interest at looking at the raper code itself since I got the kernel working well.

Can anyone help me get this to mine? I'm trying with an AMD Radeon HD 6570.. When I save the cgminer.conf it says my cgminer.conf is invalid when I open cgminer.exe.. It asks me to type in the url , username and password.. so I put in url: http://litecoincash.com:8332username: [MyUsername] password: [MyPassword] It starts mining but when I check on litecoincash.com under my workers page after a good 10-15 minutes It's still showing as worker offline

You've running an unbelievably high overclock compared to my 7970 getting 500k/hash with reaper. 925 mhz core is default, you're at 1275 mhz. that's a 38% overclock. 500 k/hash * 1.38 = 690 k/hash. I'm thinking that reaper might still be a bit faster, clock for clock. I don't want to OC my new 7970's. Otherwise i'd test it myself.

Open a CMD in the folder that you have the cgminer.exe and execute: cgminer --scrypt --lookup-gap 2 --thread-concurrency 8192 -g 2 -I 13 Edit the options: --thread-concurrency -> There are various users that use various types of values, so try different values to see what is best for you -g -> The number of threads per GPU, i think you can use 2 but you may test 4 -I -> Intensity test the best value for your hardware, try 10 to start hope i could help, i don't understand much of this put that in run line and it's working but incredibly slow... even with 13 intensity..
Whit my Nvidia 310M i get ~5kh/s xD What is the kh/s that you get?
