    Hello. As you can see on the screen above my ram timings are
    16-17-17-35 although I set the XMP profile in BIOS with the
    15-17-17-35 timings.
    I also noticed that if I change CAS latency in BIOS to 15, it jumps to 16, if I set 17, jumps to 18 etc. but if I set 16 or 18, the value doesn't change.
    My ram is Corsair Vengeance LPX 2X8GB 3000 MHz CL15 and it is compatible with my ROG B450-F GAMING.
    My BIOS version is 2301.
    What should I do? Is it a BIOS problem?
    Thanks for your help

    Not a problem just a AMD memory timing setting...
    GDM - Gear Down Mode Only Runs at even CAS Settings 15=16 17=18 19=20 ........
    Your memory may not run high bus speeds with it off... Have to test... Very Little Performance loss with it Enabled...
