i9

Hello! I just did OC of my cpu i5 9600k. I set 4,9ghz and 1,22V. Prime 95 small fft is going ok, with temps ~70C Is this voltage ok?

So I’ve had this PC for about one year now, I've had a friend help me build most of it, so I don't know much about this PC, I no longer have contact with him as well unfortunately. Ever since I first built it, my CPU has been running at 0.78GHz. I am not a computer wizard, so I don't know much...
