i have allways 100% usage on cpu. how i can fix that? 
Use latest cgminer 2.6.1 and run with --scrypt optionDid you set your shader count?
What intensity were you using?
Try intensity 18.
a 7970 can't go above 12

Use latest cgminer 2.6.1 and run with --scrypt optioni fixed the cpu problem in reaper. i have 2x 6950 and im thinking which miner i should use? cgminer or reaper?
what is that "--scrypt option" in cgminer?
thanks for helping a noob
Try using cgminer, it's more stable. The --scrypt option in cgminer is to tell it you want to mine litecoins instead of bitcoins. You also have to specify the shader count of your card. If you have trouble getting cgminer working, post your config and we can help you, or you can use cgEasy.

Has anyone made a LTC vs BTC profitability calculator? I'll start a bounty for one.
It already exists.

Oh goody, thanks!!!

So I read through this thread, then looked at btc-e's LTC/BTC and LTC/$ pages. But the coffee isn't working.
My head gets all spinny when I try to figure out whether to mine LTC on my 7970, or keep mining BTC and exchange them for LTC.
Can somebody please math this for me?

these settings get 600kh/s+, which is the estimated kh/s rate for one of these cards by their memory bandwidth:
worksize 256
aggression 13
threads_per_gpu 5
sharethreads 18
lookup_gap 2
gpu_thread_concurrency 10240
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)

I have 2 7970 on order I'll tell you next week.
All I have right now are 5970 and 6990
for those
worksize 256
aggression 16
threads_per_gpu 1
sharethreads 18
lookup_gap 2
gpu_thread_concurrency 8192
works best
and again FAST memory, unlike bitcoin.

right. play with it and see what happens. The highest you can get the memory the better. the core helps too, but memory speed is more important.
on a 6990 having the ram at 800mhz vs 1250mhz is the difference between 200khash and 800khash
on a 6990 having the ram at 800mhz vs 1250mhz is the difference between 200khash and 800khash
Duh play with it. There are just a lot of options to mess with compared to btc mining and very little info I can find. Thanks
ok delete the bin files between runs.
worksize try 128 or 256 mine for a couple of minutes and see what gets the best rate.
aggression 12-19
Lower if you want to use the box for anything and background mine or if stales are too high. Higher for dedicated. beyond 19 isnt good.
threads per gpu, try them all 1, 2 and 4. mine for a couple of minutes and see what gets the best rate.
sharethreads, lookupgap leave alone.
concurrency, start at 8192 and go up. try multiples of 1024 and again mine for a couple of minutes and see what gets the best rate
in half an hour you'll answer your own question.

Drop threads per gpu to one overclocking the memory. Litecoin is dependent on high memory speed unlike bitcoin.
All 68xx series cards are still vliw5 to my knowledge, which I think means they have a queue of 5 threads per shader. So a 6870 would be 5 * 1120 = 5600
just saw your post thx!
(stopped mining LTC for a day or so)
