Your BCK to 100

Volt should be in the 1,2 range. Try auto volt. Check after restarting, reenter BIOS, it tells you in the Voltage Monitor section. If too high (above 1,35v) , lower it. Maybe you can even use the stock voltage as 4000 is just slightly above stock.

Asus tells you with colors if the numbers are too high in the BIOS. Stay with yellow or blue numbers, never red ones.

Using an old computer (with ANOTHER processor family) to learn this, I think is overkill, unless you want to graduate in Overclocking

Pretty much this. Definitely auto voltage should be fine for even higher than 4 GHz. I would add to check if the heatsink is mounted properly.
