I know this maynot be the place to ask but I am unable to get my 2 HD3850's to crossfire. Its enabled in CCC (7.11) and GPUZ shows 2 cards enabled but my 3DMark06 score is the same (about 9000) with Cf enabled, CF off and with one card disabled in device manager.

PSU is 600W OCZ and rated for 2 graphics cards.
Asus maximus Formula - OK for CF
XP
All drivers are the most recent except my BOIs which is the orginal version.
My CPU (E6750) is OCed to 3.4GHz. Has been for a while and working without any problems. I have also set the PCIE bus to 100MHz manually rather than leaving on auot in BIOs.
I can't think of anything else to make CF work ans am supper p***ed off. Any suggestions would be very welcome as I have already trawled through forums and posted on several including AMDs without any success.
Cheers BF
