The Asrock Z77 Pro3 board has PCIe 2.0 slot and also a PCIe 3.0 slot. No when I am trying to install the HD 7850 graphics card in the PCIe 3.0 slot then it will not give any output or signal to the monitor. The same card works in PCIe 2.0 slot without any problems. So, it definitely seems like there is an issue with the motherboards PCI-E 3.0 slot because I have heard that pcie 3 are backward compatible, so the card should work but it isnt. Or do I need to change some settings to get this card to work? Please help me out. Thanks.
