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.
yes im running two of 5970. actually i can get about 1520khs but it is risky. and crashing too often.
1422khs running stable and no crash anymore about a day. hope it wont.
actually i got headaches to make this rig stable. got many errors, many crashes, cards was closer to be burned.
im noob and running this shits made me stress. but with researching threads, getting help from experienced users. it s now okey.
i also started to use cgwatcher it has some options about restarting cgminer if a gpu crashes. dead or sick gpu it also restart cgminer. so when u r sleeping or at outside it can help.
also it has some features about temp. protect. if your card gets 85+ temp. its auto lowering -I
etc etc etc.
i got many crashes with high oc'ing so i lowered core clock and memory clock. I also advice u to not make much OC.
