    Default z77 extreme4 doesnt detect r9 270x


    I am not sure what to do at this point except maybe buy a different graphic card. I ordered Sapphire Radeon R9 270X 4GB GDDR5 DVI-I/DVI-D/HDMI/DP Dual-X with Boost and OC version PCI-Express Graphics Card 11217-04-20G: Computers & Accessories and I got a replacement. Both cards when plugged in gave me no signal on my monitor. I tried using clear cmos, which didn't work. I also tried upgrading my bios from P2.90 to the latest version which didn't work either and windows still wouldn't detect my r9 270x.

    Is this problem occurring to every owner of z77 mb and those that bought the r9 270x graphic card?

    Specs for my computer are:
    Operating System
    Microsoft Windows 7 Ultimate 64-bit SP1
    Intel Core i5 3570K @ 3.40GHz
    8.00 GB Single-Channel DDR3 @ 325MHz (9-9-9-24)
    ASRock Z77 Extreme4 (CPUSocket)
    LC-32G90V ([email protected])
    Intel HD Graphics 4000
    Hard Drives
    466GB Seagate ST500DM002-1BD142 ATA Device (SATA)
    PSU = Antec High Current Gamer Series HCG-900 ATX12V v2.3 / EPS12V v2.91 SLI 80 PLUS BRONZE Power Supply -

    I take it you set the primary graphics in bios to pci?
    can't be that simple, but worth a shot ...

    Primary Graphic Adaptor is PCI Express
    I disabled the IGPU multimonitor and my display gets no signal at boot.
