problem with xfire

[philip j fry]

Right this is the deal have just brought another 4870 1gb to run in xfire put them both in using both xfire bridges and does'nt seem to matter what games or bench tests i do only 1 card seems to be being used , both cards work ok have tried them 1 at a time in diff pci-e slots aswell , ccc sees them running in xfire as does the latest gpu-z.
Have never ran cards in xfire mode before so if someone has any idea would be much appreciated.
thanks
