what is your card setup to get 1422k/hs? Two 5970s?

Yes mine is running stable too. One 5970 and one 5850 yielding ~1,125 khs. My 5970 seems to like a little OC'ing (gpu 835/mem 1100), likes 8192 TC, and also i'm not sure whether it likes 17 or 18 intensity better. 17 = more stable but 18 may get a little more hash? more volatile tho.

My only concern will be when i get a 6xxx plugged in i'm sure things will go haywire. Will have to do a -d X command to work on the 6xxx card solo, then do a gpu-fan command when running them all in tandem to identify who is who, then hopefully my batch file will make it work. Because I have no idea how to run a successful .conf file like ivan mentioned.
