Hello,
I fixed the PSU crash by changeing the PSU with a 1200W model.
But now i have other issues, AMD driver chases o stock settings when i start the 3 video cards in guiminer-scrypt. , if i try to undervolt it crahes.
At one try i got all of them working and stable at 81 degeres, but at the next tryout huge temps and driver crash.
Any ideeas?
I don't understand.
I have nearly the same set up - I get 600 mhash btc each card and 560 khash (still tweaking here) on ltc. high 70s temps, all in case, no extra fans.
What settings are you using?
