third gpu cuda wont work

i got a gtx295 and a 8600gt. the 8600gt is a cuda card but cuda wont work. boinc wont use the card.
any ideas?

To be able to use any GPU you:
a) use the <use_all_gpus> flag in cc_config.xml; see this FAQ for details.
b) may need to add a monitor or VGA dummy plug to all videocards.
c) may need to stretch the desktop over all the videocards.
