Changed my memory clock to 2400hz on Ryzen Master and now my computer won't boot up anymore. The power is working just a black screen on the monitor, I have yellow light on my B450-F motherboard. When I clicked on "save and test" the screen just went black.
I tried turn off the power and turning it back on but nothing.
I also had this question before. I unplugged my bios battery and plugged back on a few minutes later, and reboot again. After that, everything is OK. That memory clock speed is not your RAM speed but your CPU cache speed, 2400MHz is too high for it.
