The laptop does not turn on after changing the frequency of RAM

Hello, can someone help?
I have a chuwi corebook x, I changed the RAM frequency on it to 3200 and now it does not turn on. What and how to do?

Hello,
I would recommend to revert RAM frequency to original value. It’s not even going to BIOS?

I have same issues tho. Laptop is just black screen. If it will boot, I could reset to default values. I was thinking maybe there is a bios reset jumper or a cmos reset jumper on board?

The Bios need to be done with a special machine.
I can send you the BIOS if you give me your serial number, and you can try to reinstall but i am not sure that will solve it.
