windows not noticing the other gpus?

[clonedone]

i tried the 5 second dummy resistor thing, it dosent seem to work. all it did was turn the screen black and sometimes it would shut down all together. anyone know how to address this problem?
also does ubuntu require you to hook up a moniter to every gpu?

[luffy]

As far as i know, Linux doesn't need the dummy plug.
Are you using win7? do you have less than 5 GPUs and sufficient power?
Then try official catalyst 11.3 with APP (ocl).
I have problems with 11.4

ahh i was using 11.4, but either way ill still needa dummy right?
what if i use crossfire? then will i still need a dummy?
