i've received my 2 5850 extreme, installed them, no crossfire bridge and crossifre is not activated, windows recognize both cards but poclmb miner doesn't. i have both card connected to my screen (multi input screen) but the 2nd one doesn't work even if i switch from dvi to vga. poclbm just recognize 1 card..any help?

-i've tried the register thing without result
-plugging the 2nd card into my monitor should be the same thing of using a dummy

should i install the crossfire bridge between the 2 cards?

please help

I was having issues like this with two 5830's on Windows xp sp3. What solved this problem was extending the display to the second monitor (right click desktop -> properties -> setting tab). My crossfire bridge is/was off when I did this.

Hello!

It wouldn't work for me either, I had to connect me second 5850 card via HDMI to my TV in order to connect, putting an RGB and a DVI in the same monitor didn't work

Hi! well, fascistmuffin got it! thx a lot buddy, here's my configuration:

1 monitor with multi input:
-1dvi
-1vga
-1hdmi

I've plugged the miner rig using the dvi and vga inputs, then i did what FM said (just extend the desktop) and voilà, poclbm recognize the 2nd graphic card, i use TriXX to OC the first card and CCC (since trixx doesn't recognize the second...MF do you have a solution for that too? Tongue) to oc the 2nd one, i'm doing about 700+ Mhs

Thanks FM, post the adress, will send you a little tip
