Hello
I tried to lower at 300mhz and the selected card turned itself off
(holy crap!, I almost shit myself thinking that i had fried the card) the other card was still runing, powercycle and everything go back to normal.
If I lower to 500 mhz, it still works, same performance, but i start to se some crap on the screen from time to time (artifacts).
runing memory at 600mhz is stable.
I have two HD 7850 Sapphire 1GDDR5, with the GPU at 700Mhz (default is 860Mhz) I get 205Mh/s per card, it's kinda slow but I'm concern on frying the card if I push it at max speed for long periods of time, what do you think?
Default voltage is 1138, I lowered to 1130 but not sure what is convenient, I am more concerned to keep the board safe than to get more performance out of it.
Temperature is 59 C (with 27 C ambient) in both cards. (fans are in automatic at 50% PWM)
