i have 2 7970's from sapphire and i am trying to put them in crossfire. i have a Z68BC motherboard which provides for two 8x lanes for crossfire. the problem is that when i plug in both cards, my WIFI card in the PCIe x1 lane is gone. its as if it gets disabled or something like that. my question: can i even do crossfire and have a WIFI card?
Thank you for the information. We would recommend verifying if any grounding issue is faced. In that case it will be necessary to test the system out of the chassis on a non conductive surface.
Also, it is important to confirm if the power supply fills the power requirements for this configuration.
