update - i half got three cards working with an install of xubuntu - but again it all went pear shaped from there.
the only other thing i can think of is to try windows, which many seem to have had success with.
the only thing left i can think of.
again any help is appreciated, and if any one can get this running im happy to reward you
Topic: Help needed - 4 cards Ubuntu - problems (Read 537 times)
HI guys,
my problem has been going on for 4 days now and i am pulling my hair out.
my set-up
sempron 145
4gb ram (i have tried 8 also)
4 asus r280x
2 750w psu connected using an adapter
gigabyte ga-990fxa-ud3 MB
currently on Ubuntu 12.04 i have also tried 13.10
all 4 cards where connected using 2x 1x16 risers and 2x 1x16 powered risers, with a lot of trial and error, swapping and replacing etc i got 2 cards to be visable. i actually bought 6 cards as i want to add 2 to an existing rig, so have tried using different cards also.
all 4 cards are getting power as the lights come on and the fans spin.
i have tried aticonfig, i have tried installing the drivers many times, i have tried everything i can find on google....
when i connect an extra card and power up the system i get a purple screen hanging. if i disconnect the card and run with two again it boots fine.
i cannot think of anything else, i have followed numerous guides, (cryptobadger, highoncoins - on yt). i have read through hundreds of posts on here and other forums.... and i am officially stuck.
any ideas or any more info needed let me know....
my wife would also be very appreciative, i think she is about to explode if i hide away for much longer trying to fix this!
thanks
Paul
