    AMD 3700X on Crosshair VII, board fails to post if 3200 MHz Ram set over 2400 MHz

    Good Afternoon All,

    I have put an AMD Ryzen 3700X on my ASUS Crosshair VII Hero motherboard, I have overclocked the AMD Ryzen 3700X processor to 42.25 GHz on all cores with 1.36 volts on the processor. I have the latest bios, 2406 -AMD AGESA Combo-AM4

    My motherboard fails to boot if use 3200 Mhz for my G Skill Flare X 3200 DDR4 Ram (2 X 8 GB sticks), I have increase ram voltage to 1.4 volts on the ram and still it fails to boot. The motherboard stops on code "C5". Any ideas to run my 3200 ram at 3200 MHz?

    The 3700X has improved performance over the AMD Ryzen 2700X.
