    Exclamation Asus ROG x570 Crosshair VIII Hero (Wifi) RAM Speed Issue

    Hello,

    I have been having issues with my RAM speed. The current speed is running at 3466 MHz, where as my hardware speed is 3600MHz. When I set the RAM speed to anything over 3466 MHZ I cannot get post and the Motherboard displays Q Code 22. I have been testing back and forth and the maximmum number I can set without any issues is 3466MHz. I am using G.Skill TridentZ RGB Series 16GB DDR4 3600MHz. I just updated my BIOS version to V1302 but there is no change. During my tests the FCLK is set to auto which is 50% of the RAM speed. I also tested 3600MHz with 1800MHz FCLK or lower and still cannot get post and I get Q code 22.

    Here the current outcome for cmd "wmic MEMORYCHIP get BankLabel, DeviceLocator, MemoryType, TypeDetail, Capacity, Speed"
    BankLabel Capacity DeviceLocator MemoryType Speed TypeDetail
    BANK 1 8589934592 DIMM_A2 0 3466 16512

    In regard flck you reading it wrong, Flck 1800mghz = bus speed of 1800mghz (= DDR speed @ 3600) ie. 1:1 ratio
    Click image for larger version.

    Thank you for your help. I am using DIMM_B2* and DIMM_A2* slots and i changed the settings on bios as you suggested it. Everything seems to be working properly now. I highly appreciate the help.
