Powercolor 7870 LE (Tahiti) - NEED HELP!

[6strings]

The highest I've been able to get LE EZ is 380 khash. I was hoping to atleast get 420 khash or there abouts. Any less and I'm better off just mining BTC. I thought if I put my 6870 back in along with it I could use that for ltc while mining btc with the EZ, now I cant get either to mine consistantly, but I guess thats a whole 'nother kettle of fish. Might try switching to Ubuntu and see if I have better luck.

This was extremely useful for me. Other than M=1555 which was too high (1375 worked great for my Powercolor), everything else was used in cgminer 3.7.2 to increase hash by over 15%. Thanks!

BTW, my GPU  is not even Tahiti, but Pitcairn, yet the parameters hold well.

In afterburner, set core to 950 MHz and memory to 1555 MHz

use reaper and this litecoin.conf

Code:

host yourpool.com ### Do not add http://!!
port 8344
user username
pass password

protocol litecoin

worksize 256
vectors 1
aggression 20
threads_per_gpu 1
sharethreads 32
lookup_gap 2
gpu_thread_concurrency 18610

Tell me what you get
