After lots of testing with many different settings.. i would suggest this for the OP
avoid the 7870 if you are considering buying one for LTC mining
No matter how many attempts I have made with all types of different settings: I have NEVER been able to get above 330 khash on it, even at 1220/1425 clock speeds. I am easily getting 610-640 on a 7950, and considering the 7950 is only about $60 or so more than a 7870, it's not the best bang/buck by a long shot.
(that said.. 50ltc bounty for the first guy that can get me 400+ khash out of a 7870)

Vircurex is a good exchange.

use the windows binary in the command console? (start menu --> type in 'cmd')
http://ck.kolivas.org/apps/cgminer/cgminer-2.8.1-win32.zip
other than that it's the same as for unix

Any advice for windows set-up for cgminer and litecoin mining?
October 10, 2012, 11:16:39 AM
im not too sure of this , but maybe try adding -d 0 or -d 1 . coz maybe ure mining with ur cpu ?
i know its a longshot but..
cheers

Just to note that mem and core clocks (possibly their ratio) are also relevant. For example, I got significantly better results with E:850 M:1000 (350Khs) than E:900 M:1000 (310Khs) with a HD5850.

updated thread with common thread concurrency ranges, I didn't realize it but 5xxx and 6xxx cards perform the same as 7xxx cards in that memory padding size and therefore thread_concurrency have typical ranges in which the card mines the most quickly.

I got 5 Kh/s in my 6770 and PC almost hanged, for mine the best setup is :
-I 15 for Desktop
Regards
Code:
cgminer --scrypt --shaders 800 --intensity 15 -I 18 -g 1 -w256
Regards
Thread concurrency was too high, --thread-concurrency 3200 -g 1 -I 17 -w 128 should give 210kh/s

bro get some more ram its cheap as chips 
any suggested minimum RAM to get decent rates on a 5850 series ?
Usage or PC requirements?
You need about 512MB per card on the motherboard, so if you have 4x 5850s you need 3-4gb.
I mean total RAM PC requirements, it's for only 1 x 5850.
So I can assume 2 GB is OK, right ?
yup, should be totally fine.

btc-e.com
for btc/ltc exchanges it takes very little time (you'll be trading within 1-2 hours tops, no personal identification required)
I have not tried them yet for selling ltc for cash though.. I dont believe they have very 'american friendly' cash out options though, so selling for BTC and using the BTC > $$ option may be best (which I've used fastcash4bitcoins.com for that before, works great and is relatively fast with low fees).

Anyone have better CGminer setting then this for 2 6950's? I'm pulling 454 Kh/s on each card. I think I should be able to get 500 out of them.
./cgminer --scrypt -w 256 -g 1 --thread-concurrency 7104 --intensity 19 --auto-fan --auto-gpu --gpu-engine 700-935,700-935, --gpu-memclock 1300,1300 --gpu-vddc 1.10,1.10 -o litecoinpool.org:9332 -u username -p password
Thanks for the help

Have you tried --shaders 1408,1408 instead of --thread-concurrency 7104?
Regards
Or --thread-concurrency 7040 even a 5x multiple of 1408.
I have tried --shaders 1408. I loss about 20 khs. I can overclock the cpu and memory more but hashing doesnt increase much. I know people are pushing these cards over 520khs.

yeah, you probably need more ram. properly configured 5970s get ~700-800kh/s (but it also heats the VRMs/memory hotter than BTC and will probably be harder on the cards).
