cgminer is the best, and can give more then reaper, its have been proven 
Just need to configure right

Topic: LTC mining with Reaper on a 7970 - page 4. (Read 33008 times)
using -shaders i get 550kh/s and 99% hardware errors
well i dont have to configure for BTC & LTC and i get the best hashrate and best results without lag on my system cos i use my computer
but when i try to use a configured bat file for LTC with all the correct settings i get lower hashrate and lag
but when i try to use a configured bat file for LTC with all the correct settings i get lower hashrate and lag
I use it for BTC and PPC but i cannot get LTC to work it keeps saying rejected
what is you're cgminer conf?

I find reaper to be the best doin 760Kh/s on my 5970

Reaper reports higher hashrate compared with cgminer but keep this in mind:

Best bet would be to squeeze (properly) as much performance as you can from both apps, mine with both for few hours and compare share rates as they are reported by the pool.

Now finally, and you can believe me or not on this, but raper sends work to the GPU WITHOUT CHECKING if it was accepted, and gets the return buffer WITHOUT CHECKING if it actually did any work, and then adds the number of hashes it would have expected the GPU to do with that work sent to it. This means that when you start with lots of threads, some of them may not even be doing anything. Or if you've set some borderline invalid values, it will appear to be working fine, report back a big hashrate, but generate less valid shares. So I implore you to check the share rate generation and pretty much ignore the reported hashrate when comparing notes. Remember that cgminer AND raper use virtually identical kernels so should hash at virtually identical rates.

Use cgminer peeps?
set --shader and go after that instead, that was what i started with on DiCE1904 7970, and he is now getting +700 kh/s on his

Any other suggestions on settings other then that? CG miner always tends to perform (for me) about 10-15% lower then reaper can get. I have tried both the --shader and --thread-concurrency routes.

these settings get 600kh/s+, which is the estimated kh/s rate for one of these cards by their memory bandwidth:

you need the latest sdk and 12.6+ ati drivers (tried with 12.6 and it works well, not sure about 12.7 but those are probably okay too)
Any time I go above 8192 I get an error saying the buffer is too large or some shit. How are you guys getting gpu_thread_concurrency above that? worksize 256

I put 18, the kh went up to around 400, but I had Q:38 A:8
if you go above 12, its will just be stalen
you have to tweak it pretty much, i got ~700 kh/s out of my bro's 7970
with -I 12, but with som good tweaksShare the tweaks, for the good of the cryptocurrency of course.

Should be able to get 700+ kh/s. I have a 7950 running this right now and I'm getting 550 kh/s.

i have allways 100% usage on cpu. how i can fix that?
Use latest cgminer 2.6.1 and run with --scrypt option

What intensity were you using?
Try intensity 18.
a 7970 can't go above 12
Ahh, thought that was only with reaper
