I want to update my BIOS or UEFI but I've heard it can brake the CPU.

Solution


Occasionally, check and see what's new regarding BIOS updates. When there are updates, reasons will be stated. If it does not affect you, leave it alone.

If it makes OC simpler, then update the UEFI (BIOS).

However, study the update (flashing the BIOS) process as outlined by the motherboard manufacturer. Then proceed. OC is a lot of fun and you need to study the topic before doing it in gradual increments (different topic).
