Mining on a HD 6850

[afuls2013]

I've been mining for about 2 weeks with my 6850. I get around 185-200 kh/s on stock settings, with an added -I 18 into my .bat config. I've read it's possible to get 245-250 running stock, with some extra added commands in the config. I've looked for about an hour, and I can't find what config they were using.

Can anyone help a bro out?

100 Doges to whomever can assist me.

Bumping it up to 18 is quite a risk without decent cooling
