I love atitweak, simple and helps me custom set everything on my cards. Also lets me check what clocks actually stick. Great tool! The shortened syntax rocks(took me a sec to figure out though), saves time when I am testing out new cards or trying higher or lower clocks. Here is what I run right before I begin mining.
atitweak -m 725 -P 2 -A 0
atitweak -m 725 -P 1 -A 0
atitweak -e 850 -P 2 -A 0
atitweak -m 855 -P 2 -A 1
atitweak -m 855 -P 1 -A 1
atitweak -e 955 -P 2 -A 1
atitweak -f 83 -A 0
atitweak -f 70 -A 1
You know you can shorten this more (I'm lazy - less typing = more beer drinking)
atitweak -m 775 -e 850 -f 83 -A 0
atitweak -m 855 -e 995 -f 70 -A 1
Unless you have some need of running different settings for performance levels???
Thanks for the shortened syntax, will save me a couple lines now. I wrote how to use atitweak in to the
overclocking wiki for linuxcoin a couple weeks back, gives a general overview of other overclocking utilities as well, I still must say, atitweak is the best. Only problem I still have is I can't underclock memory on my 6850 more than 100mhz from core, and 125mhz on my 6950. Anybody have a good workaround for this yet? My 5770 is working great at memclock 275 though.
