Only one Graphics Card starts after S3 sleep mode

This is weird. When I power on from a shutdown or restart, both graphics cards are working fine. But when the computer goes into sleep mode, only the primary graphics card is working after I resume. Both fans are spinning, but when I go to ATI Overdrive and look at the temperatures, only the primary is showing.

Both temperatures show when the computer is turned on after shutdown or reboot.

I changed enableulps from 1 to 0 in system reg to get the second temp to show in Crossfire.

Also, I know it's not working because when I go to play a game, any game, it always crashes and says display driver recovered from error or something to that nature.

More about only graphics card starts sleep mode
  1. Don't know how or why that happens, hopefully someone do...but I do know, that the sleep mode of vista destroyed my psu long time ago ^^.

    When put to sleep and attempt to wake, the graphic card didn't respond, also it's fan started at 100% until hard power off. After the sleep thing happened 2 more times, the PC didn't cold boot anymore:S(just saying, weird things happen with sleep modes)
  2. I meant to say I'm running Win 7 x64

    Weird things do happen with sleep mode for me as well. Before I got the second 5770. Sometimes it wouldn't turn on after it was in sleep, when I went to wake it, the computer would do power cycles(fans come on, then go off) It would do that until I flip the switch on the PSU. I'm thinking of not using S3 anymore.
  3. If you can, live without sleep mode, as I hardly believe someone with the knowledge will come and enlighten us...
  4. Yea, it sucks no one knows the answer to this.
