I can't seem to get apps to run at 1920x1440 with crossfire enabled in CCC, from 3DMark03-06 and other apps.

The cards are known to be good. I'm using an MSI K9A2 Platinum MB and 2GB DDR2 Kingston RAM. I've already updated the BIOS to latest, and have updated vid card drivers. The proc is a Phenom Quad core@2.3GHz.

Is there a chipset driver update for the mobo that I should be using? That's my only option now. I'm also using a PCP&C 1KW PSU fwiw.

OS is Vista 32 Ultimate.

edit: has nothing to do with rig in sig.
 
The 3870x2 is not supported in a dual-card (quad GPU) configuration yet. The next version of the drivers, Catalyst 8.3 due next month should support two 3870x2's in a quad-GPU CrossfireX configuration.

I've got two of these cards here waiting as well. :D
 
I'm actually in development for AMD (just started last week), and I'm using a higher driver than the publicly available one. A coworker has had the cards working no problem on his system though...I'm pretty sure he's using the same mobo.
 
If you want to pass along those drivers I'll tell you if it's your mobo or your drivers. ;)
 
ehh...NDA...sorry man. Besides they'e still being worked on/new build almost every day. :)
 
The NDA I signed prevents me from leaking drivers, new cards being worked on (yes they're out there), etc. Our current beta driver does allow true 4 GPU, but its performance is being worked out to scale nicely at the moment. Thanks for the "would help" though, xp3ndrbl3. : )
