when i run all games below in windowed mode there is absolute no crash @ all
only thing i notice then is that the card's second gpu is using 2-4% resources
and first 100% and the card's clock speed stays 507/500 while it is 750/900
i am about 2 give the card back and step over 2 Nvidia but i wanne give it another shot
and posting this around in forums hoping i find a sollution for my problem somewhere
KooolaNL any question or tips plz let me know email@example.com

Test drive unlimited --> doesnt even start @ all
Left 4 dead --> freezes when joining a server
Counter strike source --> freezes when spawning
Half life deathmatch --> when connected 2 server
Grand theft auto 4 --> after i load a save game
Farcry 2 --> when game starts
Need for speed undercover --> @ ea logo
i hope this problem is gonna be fixed soon
or ati is doing it wrong or i am doing it wrong
i see alot of problems on internet about this HD4870x2 Fullscreen problem freeze restart thingy
its e8500 3.16ghz not oc
4gb OCZ 1066mhz
Asus p5q motherboard
600watt psu (olso had a 850watt while ago with same problem)
Right now I can only comment on GTA 4 as that is the only game I have installed. The game crashes at different times. Sometimes right when it loads into the game it freezes and i get a bsod. Sometimes the while playing the game just crashes to desktop while other times the game just freezes and the pc stops responding and if I leave it along i will eventually get a bsod.
I honestly think its the ATI drivers that are the cause.
If you are using the latest 8.12 have you tried using older drivers?
Have tried multiple systems/motherboards (ASUS P6T Deluxe, ASUS Maximus Formula), 2GB, 4GB, 6GB of RAM, Vista 32 bit & 64 bit, Windows 7 Beta, updating bios, drivers, patches, everything. 1000 W Silverstone power supply. 2 disk SATA Raid 0 multiboot.
This includes trying the latest 9.1 drivers from ATI, and older drivers from ATI and Diamond. Also includes "Crossfire Crash" patch fix for HD4850X2 ...
Still no dice ... any 3D Game or Benchmark, when entering Full Screen mode, Crashes to BSOD. Things run fine in windowed mode, but that turns off Crossfire .... so the problem seems to be that the HD4870X2 won't run in Crossfire mode on Vista.

Does anyone out there have their HD4870X2 working on ASUS P6T Deluxe and Vista 32 or 64 bit?
I HAVE A FIX SO FAR ON MY RIG...I TURNED UP THE FAN SPEED IN THE ATI CATALYST CONTROLL PANEL.....RAN CALL OF DUTY WORLD AT WAR 2HRS YESTERDAY AND 7HRS TODAY NO PROBLEMS OR FREEZES/REBOOT/BLUESCREEN.....MY CARDS ARE FACTORY OC...I JUST UNLOCKED IT AND CHANGED THE FAN SPEED TO 65 %.....MY GPU IS SET AT 800MHZ......MEMORY CLOCK IS 950 MHZ...FAN SPEED IS 65%..........HOPE THIS WORKS FOR YOU
