Hi i have build a mining rig with 3 radeon 5870 (1 5850 is planned to come in as soon as i have it).
I use a msi 890 fxa gd70 motherboard and a 1000W psu from corsair.
I used Nattys Narwhale guide for mining. With the phoenix miner, but i also tried the diablo miner and it didn t work with that one either.
when i have 1 Grafic card on the board its all working fine and i can mine with no problems, but a soon as i put the others on the board the whole thing gets unstable and isn t working anymore.
I already tried a completely new installation of the system but it isn t working. I also tried Installing it without sdk but no success.
If anyone has an idea, what i can do to get this thing running please help me
I will give you all information i can to get this problem solved.
( i can t write in the mining forum, thats why i write it here. If someon could relocate this thread i would be very pleased
