7870 help, Lite coin

[basscent]

I have two 7870's, and I can't get them past 300 kHash mining litecoin.
using a guiminer script, with  -Thread concurrency 8192  -worksize 256  -Vect 1 -intensity 12  -gputhread 1  , I get around 290khs.

Using cgminer With settings of
"
setx GPU_MAX_ALLOC_PERCENT 100
SET GPU_USE_SYNC_OBJECTS 1

cgminer --scrypt -o pool:port-u user -p password
--shaders 1280 --intensity 13 --worksize 256 -g 1 --lg 2 -thread-concurrency 8192"

 I get about 40. I have tried changing the various values, but nothing seems works..

Just from looking at a quick glance, it looks like it's your intensity. Try cranking it up to 17 or more if its stable

it falls apart above 12

Try these settings:  shaders 1280, intensity 17, worksize 256, g 1, lookup-gap 2, thread-concurrency 14208, gpu-engine 970, gpu-memclock 1450

I do not have much direct experience with cgminer but my buddy was saying he was getting bad hashes per sec if he 'drove it to hard'. Try a lower intensity some more, that does not work take a look at your cooling that sometime can cause issues.

Just a side note, those numbers are about what he is getting from his 7850 (i know you said 7870), 300ish.

I can't even get cgminer going anymore. It just says starting cgminer for a while, flashes some text and instantly closes.

I swear this mining litecoins thing is a myth! I've only gotten one program really working (guiminer scypt) and it does it rather slow for my particular card.
