Hi and thanks for taking the time to view my post  

I'm having some difficulty getting both my gfx cards fine tuned with cgminer, And after 2 days searching the internet for an answer Im at my wits end....... I have a dedicated 24/7 mining rig with a 7970, and my pc has a 7950. In cgminer im getting 585khs with the 7970 and 540khs with the 7950. I have tried using thread concurrency in my bat files 22400, 24000.etc (cgminer bin file uses 22400 TC) , but it always results in a lower hash rate than using the shaders command.

7950
setx GPU_MAX_ALLOC_PERCENT 100
cgminer --scrypt  -o*********************** -I 13 -w 256 --shaders 1792 -g 2 --gpu-engine 1100 --gpu-fan 65 --gpu-memclock 1250 --gpu-powertune 20 --temp-cutoff 92 --temp-overheat 86 --temp-target 80

7970
setx GPU_MAX_ALLOC_PERCENT 100
cgminer --scrypt  -o *********************** -I 13 -w 256 --shaders 2048 --gpu-engine 1125 --gpu-fan 65 --gpu-memclock 1375 --gpu-powertune 20 --temp-cutoff 92 --temp-overheat 86 --temp-target 80

using cgminer 3.7.2 version


If i increase the intensity it just results in HW errors. Ive tried lowing the mem clock 150mhz below the engine clock, gives a slightly lower hash rate.

Many thanks in advance for help!!


EDIT: 7950 found a TC that doesnt lower my hash rate (around 10~20+kh/s) of 8960
