    I've seen some problems with the newer R series cards posted here and it's usually corrected with a BIOS update.

    Did you try forcing "PCIe Link Speed" in the BIOS from its default of Auto. BIOS > Advanced > Chipset Configuration - PCIe Link Speed
    #1 - Please, when seeking help, enter the make and model of ALL parts that your system is comprised of in your Signature, or at least the model #'s in your System Specs, then "Save' it.
    ____If you are overclocking, underclocking, or undervolting any parts, informing us of this and their values would prove beneficial in helping you.

    #2 - G.Skill RAM Configurator for your boardSamsung Memory for your boardLatest AMD Chipset Drivers/WindowsLatest AMD Graphics Drivers/WindowsLatest Intel Drivers

    #3 - Please use the eXtreme Outer Vision Power Supply Calculator found HERE to determine if it might be your PSU at issue.
    ____Consider your PSU to be the foundation from which all else is built upon. Anything built upon a weak foundation is poorly built.
