My ram is supposed to be able to reach 3000MHz clock speeds, and my motherboard also supports this clock speed. I've had my ram overclocked for a few months, but after I reset my cmos because I underclocked my cpu too much, I now can't overclock my ram, my pc won't start up (stuck at windows logo) until I go back to the bios and change the clock speed to the default one. How can I fix this?
