Unlocking AMD Athlon x3 440

[n0one]

I just unlocked my amd athlon x3 440 to 4 cores, with my MSI 870a-G54 motherboard.
But when i started the computer after, it was just black. It resopnded but the screen was just black.

Do you know anything i can do to fix this?

You need to reset your BIOS / CMOS using the jumper on your MB. Look in your manual for isntructions on how to do this.

This means that your MB is unable to unlock the CPU. Unlocking CPU cores is a spotty technology, that only works sometimes. Even if the CPU is listed as a unit that can be unlocked, there is a good chance it won't actually function.
