Hi Scan,

Please help.

I recently purchased the following from yourselves (E1053481):

Antec 900 - Nine Hundred Ultimate G
850W Akasa AK-P085FG-BKUK PowerMax
Scythe Ninja Plus Rev B Fanless Hea
Akasa AK-TC5022 Ultimate non pressu
Gigabyte GA-X48-DQ6, S775, PCI-E 2.
Microsoft Windows Vista Home Premium 64bit
2 X 320 GB Hitachi HDT725032VLA360 Desk
2 X 512MB HiS HD3870 Iceq3 Turbo FullHD

I added Intel Core 2 Quad Q9450 and 4 x 2gb mushkin pc8000 ram.

I am trying to enable cross fire (I can't) but only ever see one video card in device manager, when I should see 2.

I've updated the MB bios, vista 64 and am using catalyst 8.4.

I've tried cleaning up the drivers then installing one card with drivers. Then power down install second card and boot. The trouble is that Vista only ever has one card present in device manager not 2.
I've tired each card on its own in slot one, the cards and slot work fine.
I've also tried each card on its own in slot two and they work fine.
Install both cards (with or without crossfire bridge) and vista only sees one card so does Catalyst Control Centre. Ahh....

Please help with this problem, apart from this I'm very happy with the kit.
