Hey guys,
My build is less than a year old and I recently found a second Asus Hd7850 on ebay for a steal so I ventured into crossfire... and now the problem.
The rig is an Asus Z87-Plus Mobo, Asus HD7850-DC2-2GD5-V2, OZ 750w PSU, I5-4670k (not OC), along with 1TB HD and 8G of 1866 RAM... all stashed inside my gorgeous OD green Vengeance case. The second GPU I just purchased is an Asus HD7850-DC2T-2GD5-V2...just a slight difference in the card specs. Oh, 64 bit Windows 7 as well.
I plugged in the second card, started the rig and windows did not recognize it, without the bridge in place. Seated the card again and on start up it recognized and installed a driver. Shut it down, installed the bridge and CCC prompted Crossfire. Everything was fine for a couple hours until I got my first BSOD (playing WoW, Pandora, Weather channel, and Skype).
Left both cards installed and cleared the drivers with AMDs driver cleaner. Installed the BETA drivers from AMDs website (v14.3) but received a BSOD several minutes later. Cleared the drivers again and swapped card positions so the new card is now in slot 1. Installed the regular Catalyst Suite with driver v13.251 but stilled received a BSOD about an hour later playing a Youtube video. Both times CCC was crossfire enabled and verified both cards were reading v13.251 through device manager on the second go.
I now only have the newer card in slot 1 and removed the second card. Uninstalled drivers again and reinstalled v13.251 drivers. Im at a dead end here and don't know where to head from here...possibly removing the newer card and putting my older 7850 in slot 1 to ensure thats being read correctly with v13.251 drivers and reattempting crossfire.
Any advice or direction would be greatly appreciated, if you need to know anything further about the rig let me know. Mobo BIOS has been updated through Asus' website about a month ago using EZflash.
