I am trying to mine LTC using cgminer, however the latest version doesn't work for me. I am currently using v2.6.4 because that one works and I already had it on my computer. My question is that are ~280kh/s rates typical for an 7870?

Thanks in advanced.

Not shure about 7870, but on my 7850 i getting ~387 kHash/s and i think i can get more (experimenting now). I'm using 2.11.3 cgminer.

UPD. Try to use configs like here (find your GPU in list) https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison . You must get about 400 kHash without any problems.

I'm having an issue mining LTC as well. BTC is working well for me. I'm just using nvidia gtx460m so want to mine LTC with it.
My bat file I've tried dozens of different ways, here's one example:
"setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer -o stratum+tcp://notroll.in:3333 -u buysolar.3 -p 12345 --scrypt --gpu-platform 0 -I 0"

when i run it this is the error i get:

 [2013-04-09 03:14:08] Started cgminer 2.11.4
 [2013-04-09 03:14:09] :678: error: no matching overload found for arguments of

I'm not shure, but it's some kinda problem with GPU, nVidia - is worst choise for mining. Try to change -I param (set it 1 then 2 then 3), and delete "--gpu-platform"

I tried all of that, none of it worked.
