Hello, a few days ago, I bought a BBA X1900 CROSSFIRE, to mount a CROSSFIRE next to a SAPPHIRE X1900XT. The problems that I have are I cannot to make work any game. They give me same fps activating or deactivating the CROSSFIRE.

The problem is that when activating CATALYST A.I. (default), option standard or advanced any game is executed, Windows leave errors to protection, but 3DMARK06 gives 8800 points. If I deactivate option CATALYST AI, I can execute the games without problems, but with the same speed that a single X1900. 3DMARK06 gives 5000 points :banghead:

I have tried Catalyst 6.7/6.9 and 6.10 BETA and the same thing happens.

My PC is Opteron 165@2.8GHz and DFI CFX3200 (RD580 chipset) and a Seasonic 600W

Someone has some idea?

Regards and sorry for my english, I am from Spain :eek:

yes, of course. And the crossfire activated on the CCC options...

besides, the 3DM06 isn´t does 8800 points without cable installed?. The problem, I think is the CATALYST AI option or drivers in general.

Also I tried many mainboard BIOS and anything...

regards and thank you
