Hello all,
First off thanks for having this forum and for all the wonderful support.

I have a XFX7950 that I'm running and I keep coming across people who keep saying that can easily get passed 500Kh/s with these cards while mining LTC. I can't seem to do this without having the pool and also cgminer tell me that I have lots of stales. If I keep my current settings, which are:

cgminer --scrypt --shaders 1000 --intensity 12 --worksize 256 -g 1
Temp: 80.0 C
Fan Speed: 76% (3370 RPM)
Engine Clock: 1150 MHz
Memory Clock: 1450 Mhz
Vddc: 1.250 V
Activity: 97%
Powertune: -10%
Fan autotune is disabled (0-85)
GPU engine clock autotune is disabled (900-900)

I get this below

(5s):298.5K (avg):305.8Kh/s | Q:13  A:48  R:0  HW:0  E:315%  U:7.7/m
 ST: 2  SS: 0  DW: 24  NB: 7  LW: 46  GF: 0  RF: 0  WU: 223.5
 GPU 0:  80.0C 3389RPM | 298.5K/305.8Kh/s | A:48 R:0 HW:0 U: 7.89/m I:12

It seems like anything I adjust I either use more power or my stales go up and my Kh/s on my pool goes down from what my miner says I'm doing, I understand that the pools calculate Kh/s by accepted shares so that is really my concern. Is there anything I can change to increase my Kh/s output while having my stales stay down?

Thanks in advance for any help
