I honestly haven't a clue...

I'm not sure whether or not the 4870x2 is going to expose the option to disable Crossfire support since it's supposed to default to a Crossfire mode.
A possible problem could be the default to a Crossfire Operating mode. Television mentioned some time ago that multi-gpu acceleration was somewhere in his list of things to get done. It's possible that one of the recent patches to the Live Server is trying to activate Crossfire support, but instead is generating a memory leak or other driver level problem.
I'd make sure you file a bug report of this event here: http://www.amd.com/us/CatalystCrewSurvey
I would also post it on the AMD forums: http://forums.amd.com/game/categories.cfm?catid=279
Also: I don't know if he reads his PM's right now (probably because he's busy), but I'd PM Ghost Falcon as well with the problem.
Disabling Catalyst AI on the 4870x2 is supposed to disable SLI for X2 cards. I haven't tried it for the last few driver releases, but it used to work in the past.
About three weeks ago, I started having a problem where my card was hitting 100 degrees and kicking the fan on every 15-20 seconds for 10-15 seconds. The temperature would hover between 95 and 100 for the duration of play with the activity frequently pinned at 99%. Now, even with the Ultra settings turned completely off, the card's temperature is still going up to 100 and kicking the fan on. It does not happen as frequently as with Ultra Mode enabled, but it is still happening. At this point, I have tried the following with the existing card:
-Rolled the Drivers back from 10.6 to 10.5
-Rolled the Drivers back from 10.5 to 10.4 (I absolutely know these were working without the problem as of the launch of I17)
-Disabled Catalyst AI
None of these changes did anything.
This weekend, I pulled the card and put in a 4870 (non x2). Though this card had a lower amount of memory (512MB) compared with the one I'm having problems with (1GB x2), it performed on CoX without problem. The drivers had been brought back up to current (10.6) and Ultra Mode was enabled and the card's temperature hovered in the mid 80's. If I am having a problem with Crossfire (which it seems to be), shouldn't disabling the Catalyst AI resolve that?
I do not have any problems with other games. For instance, I benchmarked Batman Arkham Asylum at an average of 59 FPS. The card never went above 82 degrees, and activity did not go above 25%. I play Call of Duty: Modern Warfare 2 and Battlefield 2: Bad Company multiplayer games without the card complaining or showing the temperature/activity that CoX does. All three of these games are considerably more graphically advanced that CoX.
I should also mention that my machine is in a 10x10 room with a window A/C unit that normally keeps the room at 70-72 degrees.
Any ideas as to what's going on or how I could resolve it?
