hello all,

Today i wanted to switch from 3-way Crossfire to 2-way by means of turning off the #2 PCI switch on the motherboard. I currently have 3 GPU's (Sapphire Radeon R9 290). The middle card has a dif BIOS and elpidia mem, the other 2 cards have the same BIOS and Hynix RAM.... (Totally not related, but FYI) Sometimes the middle card gives me trouble and i shutdown to switch it off so I can run 2x CFX in 16x/16x in the 1st and 3rd slot like its supposed to be.
Well, today i did just that. I went into GPU-z and noticed the second card was running at 8x. So i went to BIOS and checked to see if i could force gen 3 PCI.. Well one of the issues is gen 3 isnt even listed anymore on the PCI options????

Also, the MAIN issue im having is the 3rd card down is POSTing to the 2nd slot when 2 switches are on (1st and 3rd).... When I turn all but the 3rd switch off it posts to the 1st PCI express slot in PCI express post in BIOS. When I have all three switches on they post fine (16x/8x/8x) in the 1st, 2nd and 3rd slot. IDK what to do. When I have JUST the 3rd on it posts to the 1st slot....

Also I just flashed the newest BIOS in like a week ago. This issue wasnt happening before. When i would switch off the second switch the cards would run in 16x/16x and post to the proper slots..... PLEASE HELP.... I have also tried clearing CMOS. I havent rolled back BIOS yet, I wanted to see if i could get a fix first....
